USB Port You can use the USB port with a flash drive for the following functions:
Provide a centralized network backup location for Autonomous
Management Framework.
Store backup copies of configuration files.
Transfer configuration files between switches that are to have
similar configurations.
Store or transfer log files.
Store or transfer debug files (for example, the output of the SHOW
TECH-SUPPORT command).
Boot the AlliedWare Plus operating system and master
configuration file from flash drive.
Using a flash drive with the switch is optional.
NET MGMT
Ethernet
Management
Port
The switch uses the NET MGMT port as a separate routed eth0 interface.
The interface is not part of the switching matrix, but the switch can route
traffic in or out of the port from the network ports and Ethernet line card.
Here are the guidelines:
The port should only be used for initial configuration and
maintenance access to the chassis.
The NET MGMT port has a standard 8-pin RJ-45 connector and
operates at 10, 100, or 1000 Mbps in either half- or full-duplex
mode.
The default setting for the port is Auto-Negotiation, which sets the
speed and duplex mode automatically. You may disable
Auto-Negotiation and configure the port manually.
The wiring configuration of the NET MGMT port is set automatically
with automatic MDIX detection. You can disable automatic MDIX
detection and set the wiring configuration manually.
The port is referred to as eth0 in the management software.
The minimum cable requirements for the port are listed here.
10 or 100Mbps - Standard TIA/EIA 568-B-compliant Category 3
unshielded cabling.
1000Mbps - Standard TIA/EIA 568-A-compliant Category 5 or
TIA/EIA 568-B-compliant Enhanced Category 5 (Cat 5e)
unshielded cabling.
For instructions on how to configure the NET MGMT port, refer to the
Software Reference for x950 Switch, AlliedWare Plus Operating System.
The Network Management (NET MGMT) port has one Status LED,
described in Table 9.
Chapter 1: Overview
36
Console (RS-232)
Port
You use the Console Port to conduct local management sessions with the
switch. Local management sessions require a terminal or PC with a
terminal emulation program, and the management cable that comes with
the switch. The switch does not need an Internet Protocol (IP) address for
local management sessions because they are not conducted over a
network. For instructions, refer to “Starting a Local Management Session”
on page 196.
Note
The first management session of the switch can be either a local
session or a remote session over your network through the NET
MGMT port. For remote management, the switch uses either its
default IP address 192.168.42.42 or an address assigned to it by a
DHCP server. For instructions on remote management sessions,
refer to the Software Reference for x950 Switches, AlliedWare Plus
Operating System.
Switch ID LED The Switch ID LED, shown in Figure 9 on page 34 or Figure 10 on page

eco-friendly
Button
You use the eco-friendly button on the management panel to turn the
LEDs on or off. You might turn off the LEDs when you are not using them
to monitor the control and Ethernet line cards, to conserve electricity.
When the LEDs are off, the overall power consumption of the chassis is
reduced by approximately 2 watts.
The button controls all the port LEDs, except for the L/A LED for the NET
MGMT port. Additionally, the button does not control the LEDs on the
power supplies.
Note
The x950-52XSQ switch does not have the eco-friendly button.

PWR600 AC and DC Power Supplies
The x950 series switch supports the PWR600 AC and PWR600 DC power
supply units.
Here are power supply guidelines:
You can install either one or two power supplies in the switch.
A single power supply can power a fully equipped switch.
Installing two power supplies adds power redundancy.
You can install two PWR600 AC modules, two PWR600 DC
modules, or a combination of the PWR600 AC and PWR600 DC
modules on one switch.
The power supplies are installed in the PSU A and PSU B slots in
the rear panel of the chassis. If you are installing only one power
supply, Allied Telesis recommends installing it in PSU A slot
because that slot does not come with a blank slot cover.
The switch does not come with power supplies. They are
purchased separately.
The power supplies are field-replaceable and hot-swappable. If the
switch has two power supplies and one fails, you do not have to
power off the operational power supply to replace the failed unit.

Chapter 3: Virtual Chassis Stacking
72
Overview
The Virtual Chassis Stacking (VCStack) feature enables you link together
up to four x950 Switches into a virtual stack so that they function as a
single networking unit. The feature provides the following benefits:
Simplifies management - You can manage the devices as a single
unit, rather than individually. Your local and remote management
sessions automatically give you management access to all the
switches.
Reduces IP addresses - A stack requires only one IP address for
remote management access, reducing the number of IP addresses
you have to assign to network devices. The one address gives you
management access to all the stack units.
Adds feature flexibility and resiliency - Stacking gives you more
flexibility in how you can configure some features. For instance,
you can create port aggregations using ports from different
switches, rather than ports from only one switch. By distributing the
ports of an aggregation across multiple switches, you increase its
resiliency because the aggregation can continue to function,
though at a reduced bandwidth, even if a switch in a stack stops
functioning.
Reduces protocol requirements - Creating a stack might eliminate
the need to configure some protocols, such as the Virtual Router
Redundancy Protocol or Spanning Tree Protocol.
x950 Series Installation Guide for VCStack
73
Stacking Guidelines
Here are general stacking guidelines:
AlliedWare Plus v5.4.8-2 or later supports stacks of two switches.
AlliedWare Plus v5.4.9 or later supports stacks up to four switches.
AlliedWare Plus v5.4.9-2.3, v5.5.0 or later supports stacks up to
eight switches.
Note
Instructions later in this guide explain how to view the version
number of the operating software on the switches.
The VCStack feature comes standard with the AlliedWare Plus
operating software. No additional software or license is required.
The default setting for the VCStack feature on x950 Switches is
disabled. Enabling it requires rebooting the switch. Instructions
later in this guide explain how to enable the feature and reboot the
unit.
A stack can have x950-28XSQ, x950-28XTQm, and x950-52XSQ
switches.
The switches must have the same optional features licenses. If you
purchased optional features for the switches, you should install
them before assembling the stack.
The switches of a stack have to be connected together with a
network link called a stack trunk. As explained in “Stack Trunks” on
page 74, you can choose any ports on the switches to be the trunk.
Once ports are designated as members of the trunk, they cannot
be used as regular networking ports.
You should not pre-configure the features of the switches, such as
virtual LANs and spanning tree, before building the stack. The
configuration settings are likely to be discarded once the switches
begin operating as a stack.
Chapter 3: Virtual Chassis Stacking
74
Stack Trunks
The switches of a stack are connected with a physical network link called
the stack trunk. Here are general trunk guidelines:
The ports of a trunk can be 10Gbps, 40Gbps, or 100Gbps.
A stack can have only one trunk.
A trunk can have multiple physical links between switches, for
added bandwidth and resiliency.
All the ports in the trunk must be the same speed.
There are no default trunk ports.
You designate trunk ports with the STACKPORT command in the
AlliedWare Plus operating system.
Once ports are designated as trunk ports, you cannot view or
change their parameter settings.
The fiber optic transceivers or direct attach cables of a trunk must
be from Allied Telesis. Transceivers or cables from other network
equipment providers might not perform properly as trunks. For a
list of supported transceivers, refer to the Allied Telesis web site.
A stack of x950 Switches cannot include other stacking products,
such as x600 Switches.
In most cases, a trunk should have a minimum of two physical links
between switches.
If a trunk fails for any reason, the switches operate as stand-alone
devices.
You can choose the ports of a trunk from the following groups on the x950
Switches:
“Ports 1 to 24 and Ports 1 to 48,” next
“Ports 25 to 37 and Ports 49 to 61 with 40Gbps Transceivers” on
page 79
“Ports 25 to 37 and Ports 49 to 61 with 100Gbps Transceivers” on
page 80
“XEM2 Line Cards” on page 82
Ports 1 to 24 and
Ports 1 to 48
Ports 1 to 24 on the x950-28XSQ switch and ports 1 to 48 on the
x950-52XSQ switch support 1/2.5/5/10Gbps SFP/SFP+ transceivers,
while ports 1 to 24 on the x950-28XTQm switch are twisted pair ports that
support 1/2.5/5/10Gbps. Even though the ports are different on these
switches, the rules to using them as a stack trunk are mainly the same.
Here are the guidelines:
x950 Series Installation Guide for VCStack
75
The trunk can have up to eight ports per switch. The more ports in
the trunk, the greater its bandwidth and resiliency.
You can use any of the ports for the trunk.
There are no default trunk ports.
For the x950-28XTQm model, all the switches in the stack must be
the same x950-28XTQm model. To build stacks with the
x950-28XTQm model and the other two models, use ports 25, 29,
33, 37 or XEM2 Line Cards on the x950-28XSQ and
x950-28XTQm switches, or ports 49, 53, 57, 61 on the
x950-52XSQ switch.
For the x950-28XSQ and x950-52XSQ models, any combination of
two models can be in the stack.
Ports 1 to 24 in the x950-28XSQ switch and ports 1 to 48 on
x950-52XSQ switch support 1Gbps, 2.5Gbps, 5Gbps, and 10Gbps
transceivers. However, the transceivers for the trunk must be
10Gbps.
For a stack of x950-28XSQ and x950-52XSQ switches, the trunk
can consist of either 10Gbps fiber optic transceivers or, if the
switches are in the same or adjacent equipment racks, SP10TW
direct attach cables.
Ports 1 to 24 on the x950-28XTQm switch support 1/2.5/5/10Gbps.
Ports used in a trunk must operate at 10Gbps, in Auto-Negotiation.
In stacks of three of four switches, you have to connect the end
switches together to form a ring.
The following guidelines are not mandatory but they are recommended
because they can make managing or troubleshooting a trunk easier:
Use the same ports for the trunk on all the switches.
Choose consecutive ports (for example, ports 6 to 9).
When cabling the trunk links, connect together the same ports in
the switches, if possible.
Figure 27 on page 76 has examples of stacks of two, three, and four
x950-28XSQ Switches, with trunks of 10Gbps links. Here are the general
properties:
The trunks consist of four 10Gbps ports on each switch. (10Gbps
trunks can have up to eight ports per switch.)
The switches use the same consecutive ports, 1 to 4. As
mentioned earlier, the trunk ports do not have to be consecutive,
nor do they have to be the same ports on all switches. But following
the recommendations can make trunk management easier.
In stacks of three or four switches, the top and bottom switches are
connected together.so that the trunk forms a ring.
Chapter 3: Virtual Chassis Stacking
76
When possible, try cabling the same trunk ports together. For
example, if you select ports 6 to 9 as trunk ports, cable port 6 on
one switch to port 6 on the next, port 7 to port 7, and so on. Again,
this is not mandatory, but it can make managing or troubleshooting
the stack easier.

Figure 28 has examples of stacks with 10Gbps trunks for two, three, or
four x950-28XTQm Switches. The examples use ports 1 to 4 for the
trunks. As a reminder, a trunk of ports 1 to 24 can have up to eight ports
per switch and you can use any of the ports.

switch can have up to eight ports per switch and you can use any of the
ports.

Transceivers
You can also use ports 25 to 37 on the x950-28XSQ or x950-28XTQm
switch and ports 49 to 61 on the x950-52XSQ switch for stack trunks.
These ports support both 40Gbps and 100Gbps transceivers. You can use
either type of transceivers for the trunk, but the rules are slightly different.
Here are the guidelines to using 40Gbps transceivers for the trunk:
The trunk links can consist of fiber optic transceivers or QSFP1CU
or QSFP3CU direct attach cables.
Stacks can have any combination of x950-28XSQ, x950-28XTQm,
or/and x950-52XSQ switches.
For stacks of two switches, you can use two, three, or four ports
per switch for trunks. Examples are show in Figure 30.
Figure 30. Stack Trunk Examples of Two Switches with Trunk 40Gbps
Links
Chapter 3: Virtual Chassis Stacking
80
To build stacks of three or four switches, Allied Telesis
recommends using all four ports. Examples are shown in
Figure 31. Please note how the top and bottom switches are
connected to form a loop in the trunk.

100Gbps transceivers for trunks:
You can use either fiber optic transceivers or QSFP28-1CU or
QSFP28-3CU direct attach cables for the trunk links.
The trunk can have a maximum of two ports per switch.
You can use any two of the four 100Gbps ports for the trunk.
x950 Series Installation Guide for VCStack
81
Because the trunk cannot have more than two 100Gbps ports per
switch, stacks of three or four switches can have only one link
between switches.
Stacks can have any combination of x950-28XSQ, x950-28XTQm,
or/and x950-52XSQ switches.
Figure 32 illustrates stacks of two, three, and four switches, with
ports 33, 37, 57and 61 and 100Gbps links as the trunks.

XEM2 Line
Cards
Here are the guidelines for using ports on XEM2 Line Cards in the
expansion slots for trunks:
Note
The x950-52XSQ switch does not support XEM2 line cards.
Stacks can have up to four switches.
Stacks can have both x950-28XSQ and x950-28XTQm Switches.
The maximum number of links in the trunk varies by line card.
Refer to Table 27. For example, a trunk using XEM2-12XT or
XEM2-12XS Line Cards can have up to eight ports per card.
The guidelines are listed here:
1. Trunks of twisted pair ports on XEM2-8XSTm, XEM2-12XT, or
XEM2-12XTm Line Cards have to operate at 10Gbps. They cannot
be used as trunk ports at lower speeds.
2. Trunks of SFP+ ports on XEM2-8XSTm, XEM2-12XS, or XEM2-
12XS v2 Line Cards have to use 10Gbps SFP+ transceivers. They
cannot be used as trunk ports at lower speeds.
3. Allied Telesis does not recommend using the XEM2-1CQ Line Card
for a stack trunk.
Figure 33 on page 83 is an example of a stack of two switches with
a trunk of six 10Gbps links on XEM2-12XT Line Cards.

Unsupported
Trunks
The following are examples of unsupported trunks.
In stacks of three or four switches, the number of links in the trunk
has to be the same on all switches. The trunk in Figure 36 is
unsupported because the middle switch is connected to the top
and bottom switches with two links each, while the top and bottom
switches are connected with only one link.
Figure 36. Unsupported Trunk with Different Numbers of Links Between
Switches
The cables in a trunk must be all the same type: They can be all
fiber optic cables, direct attach cables, or twisted pair cables.
Trunks cannot contain different types of cables. The trunk in Figure
37 on page 85 is unsupported because it has both fiber optic and
direct attach cables.
x950 Series Installation Guide for VCStack
85
Figure 37. Unsupported Trunk with Mixed Cables
Trunks cannot have both base ports and XEM2 Line Card ports.
The unsupported trunk in Figure 38 consists of base 10Gbps ports
and ports on XEM2-12XS Line Cards.
Figure 38. Unsupported Trunk with Both Base and XEM2 Line Card Ports
Trunks cannot have links that interconnect base ports and XEM2
Line Card ports. The example trunk in Figure 39 is unsupported
because base 10Gbps ports 1 and 2 in the top switch are
connected to ports 1 and 2 on the XEM2-12XS Line Card in the
bottom switch.

In most cases, trunks should have a minimum of two links between
switches. The trunk in Figure 40 is not recommended because
there is only one link between switches. The exceptions to this are
stacks of three or four switches with trunks of base 100Gbps ports.
Refer to Figure 32 on page 81.
Figure 40. Unsupported Trunk with Only One Link Between Switches
Trunk links must be the same speed. The example in Figure 41 is
unsupported because the links are different speeds.
Figure 41. Unsupported Trunk with Different Port Speeds
Allied Telesis does not recommend using the XEM2-1CQ Line
Card for a stack trunk because it has only one transceiver port and
the switch has only one expansion port. Refer to Figure 42 on page
87. Instead, use two base 40/100Gbps transceiver ports, as shown
in Figure 32 on page 81, to build a 100Gbps trunk.

Master and Member Switches
One switch of a stack functions as a master switch. Its main functions are
listed here:
Coordinate and monitor stack operations.
Verify that the switches are using the same version of
management software. It automatically downloads its management
software over the stacking cables to switches with different
software versions.
Verify that the switches have different ID numbers. It automatically
assigns new ID numbers to resolve conflicts where two or more
switches have the same ID number.
The other switches are called member switches.
Selection of the
Master Switch
The switches of the stack designate the master switch during the
initialization process, when they are powered on or reset. They base the
selection of the master switch on the following parameters:
Stack priority numbers
MAC addresses
The stack priority number is an adjustable value of 0 to 255, where the
lower the number, the higher the priority. Typically, the switch with the
lowest priority number (highest priority) becomes the master switch of a
stack. The default priority value is 128.
If the switches have the same priority values, the selection of the master
switch is based on their MAC addresses. As with the priority value, the
lower the MAC address, the higher the priority. The switch with the lowest
MAC address becomes the master switch.
If you power on the stack without adjusting the priority values, the master
switch is selected based on the MAC addresses if the units are powered
on simultaneously. If you power on the switches one at a time, the master
switch is the first switch powered on.
Chapter 3: Virtual Chassis Stacking
90
Switch ID Numbers
Each switch must have an ID number. The range is 1 to 4. The default is 1.
The ID numbers are displayed on the ID LEDs on the front panels of the
units. You can assign the numbers yourself or let the master switch assign
the numbers automatically when you first power on the stack.
You use the ID numbers to identify the individual ports and switches when
configuring the devices with the commands in the management software.
For further information, refer to “Designating Ports in the Command Line
Interface” on page 46.
The ID numbers are also used to identify the parameter settings that are
stored in the configuration file. When the stack is reset or power cycled,
the switches uses the ID numbers in the commands in the configuration
file to determine which parameter settings belong to which switch.
Caution
You should not change the ID numbers of the switches after you
begin configuring the parameter settings. Otherwise, the stack might
apply parameter settings to the wrong devices when you reset or
power cycle it. E79
The switches do not use the ID numbers to select the master switch. The
selection of the master switch is based on the priority numbers and MAC
addresses, as previously explained.

Optional Feature Licenses
The x950 Switch comes with the AlliedWare Plus management software
and a base set of features that are available as soon as you install the
device. Additional features and capabilities might be included with the
operating system, but can be access only after they are unlocked with
optional feature licenses from Allied Telesis. Contact your authorized
reseller or distributor for a list of optional features licenses for this product.
Here are the guidelines to feature licenses for a stack of x950 Series
switches:
The VCStack feature is part of the base features of the switch. It
does not require an optional feature license.
You can install feature licenses while the switches are operating as
stand-alone units or as a stack.
When ordering feature licenses for the switches of a stack, you
must order one license for each switch.
Switches can form a stack even if they have different feature
licenses. However, the additional features are only available on
those switches with the licenses. The stack generates a warning
message if it detects that the switches do not have the same
optional feature licenses.
Chapter 3: Virtual Chassis Stacking

Planning a Stack
Here are questions you need to answer before building or configuring a
stack:
How many switches will be in the stack? AlliedWare Plus v5.4.8-2
supports stacks of two switches. AlliedWare Plus v5.4.9 or later
supports stacks up to four switches.
Which switch will be the master switch? Refer to “Master and
Member Switches” on page 89. It can be any switch.
Which ports will be the trunk ports on the switches? Refer to “Stack
Trunks” on page 74.
What will be the ID numbers of the member switches? Refer to
“Switch ID Numbers” on page 90. The master switch should be
given ID 1, the default value. Member switches should be assigned
IDs in the range of 2 to 4.
If you are planning to use ports on XEM2 Line Cards for the stack
trunk, have you already installed the cards in the switches? Refer
to “Installing an Optional XEM2 Ethernet Line Card” on page 130.
What types of transceivers will be used in ports 25, 29, 33, and 37
on the x950-28XSQ or x950-28XTQm switch, or ports, 49, 53, 57,
and 61 on the x950-52XSQ switch in the master and member
switches? Refer to “Ports for 40Gbps QSFP+ or 100Gbps QSFP28
Transceiver, or Breakout Cables” on page 29. You may install the
transceivers (but not cable them) before configuring the switches
for stacking.
Have you already connected network cables to the trunk ports? If
so, you should disconnect them before configuring the switches for
stacking.
Note
Cabling the trunk ports before activating and configuring the
VCStack feature may result in loops in your network topology, which
can cause poor network performance.

The worksheet columns are described in Table 29.
Table 29. Stacking Worksheet Columns
Column Description
Location Use this column to record the model names and
physical locations of the switches, such as their
buildings or equipment rooms. The information
can be useful in identifying and locating the
switches if they are in different locations.
ID Each switch in a stack has to have a unique ID
number, in the range of 1 to 4. They display the
numbers on the ID LEDs on the front panels and
you use the numbers to configure the individual
ports. Allied Telesis recommends assigning the
ID 1, the default value, to the master switch. You
should decide on the ID assignments of the
switches before beginning the configuration
procedures.
Priority When the switches of a stack are reset or
powered on, they perform an initialization process
that involves, in part, choosing the master switch.
The selection is based on their priority numbers
and MAC addresses. The former is an adjustable
parameter with a range of 0 to 255 and a default
value of 128. The lower the value, the higher the
priority. Thus, the switch with the lowest value
becomes the stack master.
If switches have the same priority number, the
master is selected based on their MAC
addresses. Again, as with priority numbers, the
lower the MAC address, the higher the priority.
Allied Telesis recommends setting each switch’s
priority value to match its ID value. This is to
ensure that the switch you have chosen to be the
master unit will indeed function in that role. It will
also make it possible for you to know the order in
which the switches assume the master role if the
primary master should fail or be powered off.

Use four screws per rail. Refer to Figure 101 on page 175. Installing
the switch can be easier if you leave the screws slightly loosened now
and fully tightened them after the switch is installed.
Warning
Built-in stoppers prevent the outer rails from extending beyond their
maximum length of 960 mm (37.8 in). Do not force the rails beyond
the maximum length. Otherwise, the brackets will be weakened, and
the switch may fall from the rack and be damaged. E65
Warning
Verify that the front and rear of both outer rails are attached at the
same distance from the floor, otherwise the switch may fall from the
rack. E66

Installing the Extension Brackets on the Inner Rails
The kit comes with two extension brackets. Refer to Figure 102.
Figure 102. Extension Brackets
You use the brackets to recess the switch in the equipment rack. The
maximum distance will depend on the depth of the rack. The deeper the
equipment rack, the more the switch can be recessed. The range is
approximately 40mm (1.6 in.) to 453mm (17.8 in.). Figure 103 is an
example.

Measuring the
Extension
Bracket Lengths
The first step is to decide how much you want to recess the front panel of
the switch in the rack and then measure the distance. That will tell you the
approximate lengths of the extension brackets. Perform the following
procedure:
1. Slide one of the inner rails into an outer rail. Be sure that the UP arrow
on the inner rail is pointing up. Refer to Figure 104 on page 177.

Installing the Inner Rails on the Switch
The sides of the x950-28XSQ and x950-28XTQm switches have two sets
of bracket screw holes. The smaller M3 holes are for the standard
brackets that come with the switch and the larger M4 screw holes are for
the inner rails of the RKMT-SL01 sliding rack. The inner rails are attached
to the switch with four M4 screws on each side. Figure 113 identifies the
respective screw holes on the sides of the switch and inner rails.
Figure 113. Inner Rail Screw Holes for the x950-28XSQ and x950-
28XTQm Switches
The x950-52XSQ switch has only M4 holes on its two sides. The holes are
used for both the standard brackets included with the device and the rails
for the sliding equipment rack. Figure 114 identifies the screw holes for
attaching the inner rails to the switch.

Command Summary
The following sections briefly describe the commands for configuring the
master and member switches for stacking. For further instructions, refer to
the Software Reference for x950 Switch, AlliedWare Plus Operating
System. After reviewing the commands, go to “General Steps for the
Master Switch” on page 198 to begin the configuration procedures.
PLATFORM
PORTMODE
INTERFACE
This command is used to configure ports 25, 29, 33, 37 on the
x950-28XSQ and x950-28XTQm switches and port 49, 53, 57, 61 on the
x950-52XSQ switch for the following types of transceivers and cables:
40Gbps QSFP+ transceivers
100Gbps QSFP28 transceivers
40Gbps to 10Gbps breakout cables
Note
You must reset the switch after designating ports for 100Gbps
transceivers or after replacing 100Gbps transceivers with 40Gbps
transceivers or breakout cables.
Allied Telesis recommends configuring these ports during the initial
configuration procedure even if they will not be used for the stack trunk.
The command format is shown here:
platform portmode interface ports 40g|100g|10gx4
The variables are defined here:
The PORTS variable specifies the ports to be configured. The
values are PORTn.0.25, PORTn.0.29, PORTn.0.33, PORTn.0.37,
PORTn.0.49, PORTn.0.53, PORTn.0.57, and PORTn.0.61. The
“n” variable is the switch’s ID. You can configure more than one
port at a time.
The “40g” parameter configures ports for 40Gbps QSFP+
transceivers. This is the default setting.
The “100g” parameter configures ports for 100Gbps QSFP28
transceivers.
The “10gx4” parameter configures ports for 10Gbps breakout
cables.
This example configures ports 33 and 37 for 100Gbps QSFP28
transceivers:
x950 Series Installation Guide for VCStack
189
awplus(config)# platform portmode interface
port1.0.33,port1.0.37 100g
This example configures port 25 for a breakout cable:
awplus(config)# platform portmode interface port1.0.25
10gx4
This example restores the default settings for ports 49 and 53 to 40Gbps
QSFP+ transceivers:
awplus(config)# platform portmode interface
port1.0.49,port1.0.53 40g
For background information on port numbering, refer to “Designating Ports
in the Command Line Interface” on page 46.
STACKPORT You use this command to designate the ports of the stack trunk. The
command has to be performed after you have enabled the stacking feature
with the STACK ENABLE command. Additionally, it has to be performed
from the Interface mode of the selected ports. In this example, ports 1 to 4
on the switch are designated as ports of the stack trunk:
awplus(config)# interface port1.0.1-1.0.4
awplus(config-if)# stackport
The command for removing the stacking function from ports is the NO
STACKPORT command. You might perform the command if you assign
the stacking function to the wrong ports or decide to change the trunk
ports. Like the STACKPORT command, it has to be performed from the
Interface mode, This example removes the stacking function from ports 6
and 8:
awplus(config)# interface port1.0.6,port1.0.8
awplus(config-if)# no stackport
As explained in “Designating Ports in the Command Line Interface” on
page 46, you need to adjust the PORT parameter depending on the ID
number of the switch. This example designates ports 33 and 37 as the
trunk ports on a switch with the ID number 2:
awplus(config)# interface port2.0.33,port2.0.37
awplus(config-if)# stackport
STACK
ENABLE
This command, which is located in the Global Configuration mode, is used
to activate the VCStack feature. Activating the VCStack feature requires
resetting the switch. You must perform this command before designating
the ports of the stack trunk with the STACKPORT command. Here is the
command:
awplus(config)# stack enable
Chapter 10: Configuring the Master Switch
190
STACK
PRIORITY
This command is used to assign priority numbers to switches.Switches
use the numbers to select the master switch. The lower the number the
higher the priority. The unit with the lowest number becomes the master. If
they have the same priority value, they use their MAC addresses to
determine the master. As with priority numbers, the lower the MAC
address, the higher the priority. A switch can have only one priority
number.
Allied Telesis recommends making a switch’s priority and ID numbers the
same. This is not required, but it can make managing and troubleshooting
a stack easier.
The format of the command, which is in the Global Configuration mode, is
shown here:
stack switch_ID priority priority_number
The variables are defined here:
switch_ID - This is the ID number of the switch. The range is 1 to 8.
You can specify only one ID number.
priority_number - This is the new priority number for the switch.
You can specify only one number. The range is 0 to 255. The
default is 128.
This example assigns the priority 1 to the switch with ID 1:
awplus(config)# stack 1 priority 1
STACK
RENUMBER
Every switch in a stack has to have a unique ID number assigned with this
command. Here is the format.
stack current_switch_ID renumber new_switch_ID
The variables are defined here:
current_switch_ID - This is the current ID number of the switch.
You can specify only one ID number.
new_switch_ID - This is the new ID number for the switch. You can
specify only one number. The range is 1 to 8. The default is 1.
Changing the ID number requires resetting the switch.
This example changes the switch’s ID from the default 1 to 2:
awplus(config)# stack 1 renumber 2
SWITCH
PROVISION
To ensure that the first power-on of the stack is successful, Allied Telesis
recommends configuring the units such that each unit knows about the
others prior to forming the stack. This involves using the SWITCH
x950 Series Installation Guide for VCStack
191
PROVISION command to add the switches as provisioned units on all the
devices. Here is the format of the command:
switch switch_ID provision x950-28
This example adds a provisioned switch with the ID 2 to the current switch:
awplus(config)# switch 2 provision x950-28
This example adds a provisioned switch with the ID 3 to the current switch:
awplus(config)# switch 3 provision x950-28

Starting a Local Management Session
This procedure explains how to start a local management session on the
switch. It assumes that you powered on the device and waited two
minutes for it to initialize its operating software.
Note
The first management session of the switch can be either a local
session, as explained in this section, or a remote session over your
network through the NET MGMT port. For remote management, the
switch uses either its default IP address 192.168.42.42 or an
address assigned to it by a DHCP server. For instructions on how to
start a remote management session, refer to the Software
Reference for x950 Switches, AlliedWare Plus Operating System.

General Steps for the Master Switch
The procedure for configuring the master switch is divided into two parts.
Here are the general steps to “Configuring the Master Switch - Part I” on
page 200.
Note
The procedures require reseting the switch. Some network traffic will
be lost if the unit is already connected to an active network.
1. Start a local management session on the switch.
2. Verify the hardware with the SHOW SYSTEM ENVIRONMENT
command in the Privilege Exec mode.
3. Display the firmware version number with the SHOW VERSION
command.
4. Enable the VCStack feature with the STACK ENABLE command in the
Global Configuration mode.
5. Assign the master switch the priority 1 with the STACK PRIORITY
command in the Global Configuration mode. This is to ensure that it
acts as the master switch during the first power-on of the stack.
6. Add the member switches as provisioned units to the master switch,
with the SWITCH PROVISION command. This step is to ensure that
the master switch knows about the member switch during the first
power-on of the stack.
7. Save your changes with the WRITE command in the Privilege Exec
mode.
8. Reboot the switch with the REBOOT command.
Here are the general steps to “Configuring the Master Switch - Part II” on
page 203:
1. Start a new local management session.
2. Designate the types of transceivers to be used in ports 25 to 37 for the
x950-28XSQ and x950-28XTQm switch and in ports 49 to 61 for the
x950-52XSQ switch with the PLATFORM PORTMODE INTERFACE
command, on the master and provisioned member switches. Allied
Telesis recommends performing this task at this time even if you are
not using those ports as the stack trunk.
x950 Series Installation Guide for VCStack
199
3. Designate the ports of the stack trunk on the master and provisioned
member switches with the STACKPORT command in the port
Interface mode.
4. Save your changes with the WRITE command in the Privilege Exec
mode.
5. Reboot the switch with the REBOOT command.
6. Verify the changes with the SHOW STACK and SHOW RUNNING-
CONFIG commands.

Steps 4 designates the types of transceivers to be used in ports 25, 29, 33, and 37 for the
x950-28XSQ and x950-28XTQm switches or in ports 49, 53, 57, and 61 for the x950-52XSQ
switch on the master switch. The ports support 40Gbps QSFP+ transceivers, 100Gbps
QSFP28 transceivers, and 40Gbps to 10Gbps breakout cables. The default is 40Gbps QSFP+
transceivers.
4 Designate the types of transceivers to be used in ports 25, 29, 33, and 37 for the
x950-28XSQ and x950-28XTQm switches or in ports 49, 53, 57, and 61 for the
x950-52XSQ switch on the master switch with the PLATFORM PORTMODE
INTERFACE command in the Global Configuration mode. You can skip this step for
ports that will be using 40Gbps QSFP+ transceivers because that is the default
setting. You can also skip this step and configure the ports later if you are not using
100Gbps transceivers for the stack trunk. For more information, refer to “Ports for
40Gbps QSFP+ or 100Gbps QSFP28 Transceiver, or Breakout Cables” on page 29
and “PLATFORM PORTMODE INTERFACE” on page 188.
This example configures ports 33 and 37 for 100Gbps transceivers on the master
switch:
awplus(config)# platform portmode interface port1.0.33-1.0.37 100g
Steps 5 to 7 designate the stack ports on the master switch with the STACKPORT command.
Chapter 10: Configuring the Master Switch

7Return to the Global Configuration mode.
awplus(config-if)# exit
Steps 8 designates the types of transceivers to be used in ports 25, 29, 33, and 37 for the
x950-28XSQ and x950-28XTQm switches or in ports 49, 53, 57, and 61 for the x950-52XSQ
switch on the provisioned member switches. The ports support 40Gbps QSFP+ transceivers,
100Gbps QSFP28 transceivers, and 40Gbps to 10Gbps breakout cables. The default is
40Gbps QSFP+ transceivers.
8Configure ports 25, 29, 33, and 37 for the x950-28XSQ and x950-28XTQm switches
or in ports 49, 53, 57, and 61 for the x950-52XSQ switch on the provisioned member
switches for the appropriate transceivers, with the PLATFORM PORTMODE
INTERFACE command. For more information, refer to “Ports for 40Gbps QSFP+ or
100Gbps QSFP28 Transceiver, or Breakout Cables” on page 29 and “PLATFORM
PORTMODE INTERFACE” on page 188.
This example assumes a stack with three member switches (port2 to port4) that will
use 100Gbps transceivers in ports 33 and 37:
awplus(config)# platform portmode interface port2.0.33-2.0.37 100g
awplus(config)# platform portmode interface port3.0.33-3.0.37 100g
awplus(config)# platform portmode interface port4.0.33-4.0.37 100g
Steps 9 and 10 designate the stack ports on the provisioned switches with the STACKPORT
command.
9Enter the port Interface modes of the ports that will be the stack trunk on the
provisioned member switches. This example assumes the stack will have three
member switches and the stack ports are 33 and 37. Be sure to modify the command
to specify the ports for your stack trunk.
awplus(config)# interface port2.0.33-2.0.37,port3.0.33-3.0.37,

General Steps for Member Switches
The procedure for configuring a member switch is divided into two parts.
Here are the general steps to “Configuring a Member Switch - Part I” on
page 212I:
Note
The procedures require resetting a member switch twice. Network
traffic will be lost if it is already connected to an active network.
1. Start a local management session on a member switch.
2. Verify the hardware with the SHOW SYSTEM ENVIRONMENT
command in the Privilege Exec mode.
3. Enable the VCStack feature with the STACK ENABLE command in the
Global Configuration mode.
4. Assign the member switch its unique ID number in the range 2 to 4,
with the STACK RENUMBER command in the Global Configuration
mode.
5. If the stack will have three or four switches, add the other member
switches as provisioned switches, with the SWITCH PROVISION
command.
6. Save your changes with the WRITE command in the Privilege Exec
mode.
7. Restart the switch with the REBOOT command.
Here are the general steps to “Configuring a Member Switch - Part II” on
page 215:
1. Start a new local management session.
2. Change the switch’s priority number to match its ID number, with the
STACK PRIORITY command in the Global Configuration mode.
3. Specify the types of transceivers to be used in slots 25, 29, 33, and 37
for the x950-28XSQ and x950-28XTQm switches, or in slots 49, 53,
57, 61 for the x950-52XSQ switch on the master and member switches
with the PLATFORM PORTMODE INTERFACE command.
4. Designate the ports of the stack trunk on the master and member
switches with the STACKPORT command in the port Interface mode.

% Please check that the new MAC 0000.cd37.0431 is unique within the
network.
% Save the config and restart the system for this change to take
effect.
8 Assign a unique ID number in the range of 2 to 4 to the member switch with the
STACK RENUMBER command. This example assigns the ID number 2 to the switch.
awplus(config)# stack 1 renumber 2
% Warning: Stacking is currently disabled.
% Warning: the new ID will not become effective until the stack-
member reboots.
% Warning: the boot configuration may now be invalid.
9Add the other member switches as provisioned switches to the member switch, with
the SWITCH PROVISION command, assigning them their unique IDs in the range of
2 to 4. This example adds two provisioned switches, with the IDs 3 and 4:
awplus(config)# switch 3 provision x950-28
awplus(config)# switch 4 provision x950-28
10 Return to the Privileged Exec mode.

Cabling Twisted Pair Ports
This section applies to the twisted pair ports on the following products:
x950-28XTQm Switch
XEM2-8XSTm Line Card
XEM2-12XT Line Card
XEM2-12XTm Line Card
Here are the cabling guidelines:
Here are the minimum cable requirements:
– 100Mbps - Standard TIA/EIA 568-B-compliant
Category 3 unshielded cabling.
– 1/2.5/5Gbps - Standard TIA/EIA 568-A-compliant
Category 5 or TIA/EIA 568-B-compliant Enhanced
Category 5 (Cat 5e) unshielded cabling.
– 10Gbps -Standard TIA/EIA 568-C-compliant
Category 6a unshielded cabling.
The connectors on the cables should fit snugly into the ports, and
the tabs should lock the connectors into place.
The default speed setting for the ports is Auto-Negotiation. This
setting is appropriate for ports connected to network devices that
also support Auto-Negotiation.
The ports must be set to Auto-Negotiation, the default setting, to
operate at 1Gbps or higher speeds.
The ports support full-duplex only.
Do not attach cables to ports of static or LACP port trunks until
after you have configured the ports on the switch. Otherwise, the
ports will form network loops that can adversely affect network
performance.
x950 Series Installation Guide for VCStack

Guidelines to Handling Twisted Pair or Fiber Optic Transceivers
Please review the following guidelines before installing twisted pair or fiber
optic transceivers:
Transceivers are hot-swappable. You can install them while the
chassis is powered on.
For a list of supported transceivers, refer to the product data sheet
on the Allied Telesis web site.
The operational specifications and fiber optic cable requirements
are provided in the documents included with the transceivers.
You should install transceivers in XEM2 line cards before
connecting their fiber optic cables.
Fiber optic transceivers are dust sensitive. Always keep the plug in
the optical bores when a fiber optic cable is not installed, or when
you store the transceiver. When you do remove the plug, keep it for
future use.
Repetitive removal or insertion of transceivers can lead to
premature failures.

Problem 3: A 1Gbps or 10Gbps fiber optic transceiver in a base port
(ports 1 to 24) of the x950-28XSQ switch or a base port of the
x950-52XSQ switch (ports 1 to 48) is unable to establish a link to a
network device.
Solutions: Try the following:
Check that the transceiver is fully inserted in the port.
Verify that the fiber optic cable is securely connected to the port on
the transceiver and the remote network device.
Verify that the remote network device is operating properly.
Verify that the operating specifications of the fiber optic ports on
the transceiver and remote network device are compatible.
Verify that the correct type of fiber optic cabling is being used.
Verify that the port is connected to the correct fiber optic cable.
Try connecting another network device to the fiber optic port using
a different cable. If the port is able to establish a link, then the
problem is with the cable or with the other network device.
Use the switch’s management software to verify that the port is
enabled.
If the remote network device is a managed device, use its
management firmware to determine whether its port is enabled.
If the problem is with two BiDi (bi-directional) transceivers, refer to
their data sheets to verify that their transmission and reception
frequencies are opposite each other. For instance, a BiDi
transceiver that transmits and receives at 1310nm and 1550nm,
respectively, has to be connected to a transceiver that transmits
and receives at 1550nm and 1310nm, respectively. Two BiDi
transceivers will not establish a link if they transmit and receive at
the same frequencies.
Test the attenuation of both directions on the fiber optic cable with
a fiber optic tester to determine whether the optical signal is too
weak or strong.
Problem 4: A 40Gbps or 100Gbps fiber optic transceiver in port 25, 29,
33, or 37 on the x950-28XSQ or x950-28XTQm switch, or in port 49, 53,
57, or 61 on the x950-52XSQ switch cannot establish a link with a network
device.
Solutions: Try the following:
Review the solutions to Problem 3.
x950 Series Installation Guide for VCStack
259
Use the SHOW PLATFORM command to confirm that the port is
configured correctly for the transceiver. If necessary, use the
PLATFORM PORTMODE INTERFACE command to configure the
port. For more information, refer to “PLATFORM PORTMODE
INTERFACE” on page 188.
Changing a port from a 40Gbps transceiver or breakout cable to a
100Gbps transceiver requires resetting the switch. The same is
also true when replacing a 100Gbps transceiver with a 40Gbps
transceiver or breakout cable.
If the problem is with an 100Gbps transceiver, you might need to
adjust the Forward Error Correction (FEC) parameter on the port,
with the FEC command. Refer to the Software Reference for x950
Switch, AlliedWare Plus Operating System.
Problem 5: A 4x10Gbps breakout cable in port 25, 29, 33, or 37 on the
x950-28XSQ or x950-28XTQm switch, or in port 49, 53, 57, or 61 on the
x950-52XSQ switch cannot establish links with network devices.
Solutions: Try the following:
Check that the cable is fully inserted in the port.
Verify that the breakout cables are securely connected to the ports
on the network devices.
Use the SHOW PLATFORM command to confirm that the port is
configured for a breakout cable. If necessary, use the PLATFORM
PORTMODE INTERFACE command to configure the port. For
more information, refer to “PLATFORM PORTMODE INTERFACE”
on page 188.
If the port previously had a 100Gbps transceiver, you must reset
the switch after configuring it for a breakout cable.
Problem 6: An XEM2 line card in the expansion slot is not functioning.
Solutions: Try the following:
Visually inspect the card to verify that it is fully inserted into the
expansion slot.
If the problem is with an XEM2-12XTm Card, the switch might have
an earlier version of the AlliedWare Plus software that does not
support the card. The card requires v5.4.9-1 or later. Use the
SHOW VERSION command to display the version number.
Try installing the card in a different switch. If it still does not work,
the problem is probably with the card. Replace the card.
Try installing a different card in the switch. If the replacement card
fails to work, the problem is probably with the switch. Contact your
Allied Telesis sales representative for assistance.
Chapter 15: Troubleshooting
260
Problem 7: An SFP, SFP+, or QSFP+ transceiver in an XEM2 line card is
unable to establish a link to another network device.
Solutions: Try the solutions to Problem 3.
Problem 8: A twisted pair port on the x950-28XTQm switch or an XEM2
line card cannot establish a link with a network device.
Solutions: Try the following:
Verify that the network device connected to the twisted pair port is
powered on and is operating properly.
Verify that the network device operates at a speed supported by
the card. The ports on the XEM2-12XT Card support 100Mbps and
1/10Gbps. The ports on the x950-28XTQm switch and
XEM2-8XSTm and XEM2-12XTm Cards support 100Mbps and
1/2.5/5/10Gbps. The ports do not support 10Mbps devices.
If the XEM2-12XT Card cannot establish links with 100Mbps
devices, the switch might have an earlier version of the AlliedWare
Plus management software. Support for 100Mbps devices on the
XEM2-12XT Card was added in version 5.4.9-1. Use the SHOW
VERSION command to display the version number. If necessary,
update the management software.
Try connecting another network device to the twisted pair port with
a different cable. If the twisted pair port is able to establish a link,
then the problem is with the cable or the other network device.
Verify that the twisted pair cable does not exceed 100 meters (328
feet).
Verify that you are using the appropriate category of twisted pair
cable. Refer to “Cabling Twisted Pair Ports” on page 226.
Verify that the port is connected to the correct twisted pair cable.
Note
1GBase/10GBase connections may require five to ten seconds to
establish links.
Problem 9: The SHOW STACK command is not displaying all the
switches in the stack.
Solutions: The switches are unable to form the stack. Try the following:
The switches might have an earlier version of the management
software that does not support VCStack, or they might have
different versions. The version must be 5.4.8-2 or later. You can
view the version number with the SHOW VERSION command.
Review the information in “Stack Trunks” on page 74 to verify that
the trunk complies with all rules and restrictions.
x950 Series Installation Guide for VCStack
261
If the trunk is using fiber optic transceivers, verify that they are fully
inserted into the ports.
Verify that the transceivers are from Allied Telesis.
Verify that the fiber optic cables are securely connected to the
ports on the transceivers.
Display the running configurations and confirm the ports of the
stack trunk. They are identified by the STACKPORT command. In
this example from a running configuration, ports 1 to 4 are the
stack trunk:
interface port1.0.1-1.0.4
stackport
If necessary, repeat the STACKPORT command. For information,
refer to “STACKPORT” on page 189. Afterwards, save your
changes and reboot the switch.
Problem 10: You removed a port from a stack trunk with the NO
STACKPORT command, but the port is still not forwarding regular
Ethernet traffic.
Display the running configuration to verify that the port is no longer
part of the stack trunk.
You have to reboot the switch whenever you add or remove ports
from stack trunks with the STACKPORT and NO STACKPORT
commands. Be sure to save the change to the configuration file
with the WRITE command before rebooting the unit.
Problem 11: The switch overheats and shuts down.
Solutions: Try the following:
Verify that the location of the switch allows for adequate airflow.
