CHAPTER 1
Getting to Know Your Switch
This chapter introduces the main features and applications of the Switch.
1.1 Introduction
The GS1900 series is a new generation Gigabit Ethernet (GbE) Web-Managed Switch.
This User’s Guide covers the following models:
See the datasheet for a full list of firmware features av ailable on the Sw itch.
1.1.1 Bridging Example
In this example the Switch connects different company departments (RD and Sales) to the
corporate backbone. It can alleviate bandwidth contention and eliminate server and network
bottlenecks. All users that need high bandwidth can connect to high-speed department servers via
the Switch.

Figure 1 Bridging Application
1.1.2 Gigabit Ethernet to the Desktop
The Switch is an ideal solution for small networks which demand high bandwidth for a group of
heavy tr affic users. You can connect computers and servers directly to the Switch’s port or connect
other switches to the Switch.
In this example, all computers can share high-speed applications on the server and access the
Internet. To expand the network, simply add more networking devices such as switches, routers,
computers, print servers and so on.
Figure 2 Gigabit to the Desktop
1.1.3 IEEE 802.1Q VLAN Application Example
A VLAN (Virtual Local Area Network) allows a ph ysical network to be partitioned into multiple logical
networks. Stations on a logical network belong to one or more groups. With VLAN, a station cannot
Backbone
RD Sales
Internet
Chapter 1 Getting to Know Your Switch
GS1900 Series User’s Guide
17
directly talk to or hear from stations that are not in the same group(s) unless such traffic first goes
through a router.
For more information on VLANs, refer to Chapter 9 on page 62.
1.1.3.1 Tag-based VLAN Example
Ports in the same VLAN group share the same frame broadcast domain, thus increasing network
performance by reducing broadcast traffic. VLAN groups can be modified at any time by adding,
moving or changing ports without any re-cabling.
Shared resources such as a server can be used by all ports in the same VLAN as the server. In the
following figure only ports that need access to the server need to be part of VLAN 1. Ports can
belong to other VLAN groups too.
Figure 3 Shared Server Using VLAN Example
1.1.4 IPv6 Support
IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The
increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 1038 IP
addresses. At the time of writing, the Switch supports the following features.
• Static address assignment and stateless auto-configuration
• Neighbor Discovery Protocol (a protocol used to discover other IPv6 devices in a network)
• Remote Management using PING, SNMP, HTTP and TFTP services
• ICMPv6 to report errors encountered in packet processing and perform diagnostic functions, such
as "PING”
• IPv4/IPv6 dual stack; the Switch can run IPv4 and IPv6 at the same time
•DHCPv6 client
Chapter 1 Getting to Know Your Switch
GS1900 Series User’s Guide
18
1.2 Ways to Manage the Switch
Use any of the following methods to manage the Switch.
• Web Configurator. This is recommended for everyday management of the Switch using a
(supported) web browser. See Chapter 5 on page 33.
• TFTP. Use Trivial File Transfer Protocol for firmware upgrades and configuration backup/restore.
See Section 32.1 on page 213, Section 32. 3 on page 215, and Section 32.4 on page 217
• SNMP. The device can be configured by a SNMP manager. See Section 31.3 on page 199.
1.3 Good Habits for Managing the Switch
Do the following things regularly to make the Switch more secure and to manage the Switch more
effectively.
• Change the password . Use a pass w ord that’s not easy to guess and that consists of different
types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier
working configuration may be useful if the device becomes unstable or even crashes. If you
forget your password, you will have to reset the Switch to its factory default settings. If you
backed up an earlier configur ation file, you would not have to totally re-configure the S witch. You
could simply restore your last configuration.

CHAPTER 2
Hardware Installation and Connection
This chapter shows you how to install and connect the Switch.
2.1 Freestanding Installation
1Make sure the Switch is clean and dry.
2Set the Switch on a smooth, level surface strong enough to support the weight of the Switch and
the connected cables. Make sure there is a power outlet nearby.
3Make sure there is enough clearance around the Switch to allow air circulation and the attachment
of cables and the power cord.
4Remo ve the adhesiv e backing from the rubber feet.
5Attach the rubber feet to each corner on the bottom of the Switch. These rubber feet help protect
the Switch from shock or vibration and ensure space between devices when stacking.
Figure 4 Attaching Rubber Feet
Note: Do NOT block the ventilation holes. Leave space between devices when stacking.
Note: For proper ventilation, allow at least 4 inches (10 cm) of clearance at the front and
3.4 inches (8 cm) at the back of the Switch. This is espec ial l y important for
enclosed rack installations.
Chapter 2 Hardware Installation and Connection
GS1900 Series User’s Guide
20
2.2 Hardware Installation
See Table 1 on page 15 for a comparison of the hardware installation methods of each model:
Note: Ask an authorized technician to attach the Switch to the r ack/wall.
Refer to Section 2.2.2 on page 21 for rack-mounting instructions. Take note of the following:
• The Switch should have a minimum 25 mm space around it for ventilation.
• The Switch should be placed on a desk that has a level surface and that is able to support the
weight of the Switch.
To start using it, simply connect the power cables and turn on the Switch.
2.2.1 Wall Mounting
Do the following to attach your Switch to a wall.
See the following table for how far apart to place the screws.
Screw the two screws provided with your S witch into the wall (see the figure in step 2). Use screws
with 6 mm ~ 8 mm (0.24" ~ 0.31") wide heads. Do not screw the screws all the wa y in to the wall;
leave a small gap between the head of the screw and the wall.
The gap must be big enough for the screw heads to slide into the screw slots and the connection
cables to run down the back of the Switch.
Note: Make sure the screws are securely fixed to the wall and strong enough to hold the
weight of the Switch with the connection cables.
Align the holes on the back of the Switch with the screws on the wall. Hang the Switch on the
screws.

The Switch should be wall-mounted horizontally. The Switch's side
panels with ventilation slots should not be facing up or down as this
position is less safe.
2.2.2 Rack Mounting
The Switch can be mounted on an EIA standard size, 19-inch rack or in a wiring closet with other
equipment. Follow the steps below to mount your Switch on a standard EIA rack using a ra ck-
mounting kit.
Rack-mounted Installation Requirements
• Two mounting brackets.
• Eight M3 flat head screws and a #2 Philips screwdriver.
• Four M5 flat head screws and a #2 Philips screwdriver.
Failure to use the proper screws may damage the unit.
Precautions
• Make sure the rack will safely support the combined weight of all the equipment it contains.
• Make sure the position of the Switch does not make the rack unstable or top-heavy. Take all
necessary precautions to anchor the rack securely before installing the unit.
Attaching the Mounting Brackets to the Switch
1Po sition a mounting bracket on one side of the Switch, lining up the four screw holes on the brack et
with the screw holes on the side of the Switch.

3.1.1 Ethernet Ports
The Switch has 1000Base-T auto-negotiating, auto-crossover Ethernet ports. In 10/100/1000 Mbps
Gigabit Ethernet, the speed can be 10Mbps, 100 Mbps or 1000 Mbps. The duplex mode can be both
half or full duplex at 100 Mbps and full duplex only at 1000 Mbps.
Chapter 3 Hardware Overview
GS1900 Series User’s Guide
26
An auto-negotiating port can detect and adjust to the optimum Ethernet speed (10/100/1000
Mbps) and duplex mode (full duplex or half duplex) of the connected device.
An auto-crossover (auto-MDI/MDI - X) port automatically works with a str aight-through or crossover
Ethernet cable.
3.1.1.1 Default Ethernet Settings
The factory default negotiation settings for the Ethernet ports on the Switch are:
• Speed: Auto
•Duplex: Auto
• Flow control: Off
3.1.2 SFP Slots
These are slots for Small Form-Factor Pluggable (SFP) transceivers. A transceiver is a single unit
that houses a transmitter and a receiver. Use a transceiver to connect a fiber-optic cable to the
Switch. The Switch does not come with transceivers. You must use transceivers that comply with
the Small Form-Factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA). See the SFF
committee’s INF-8074i specification Rev 1.0 for details.
You can change transceivers while the Switch is operating. You can use different transceivers to
connect to Ethernet switches with different types of fiber-optic connectors.
• Type: SFP connection interface
• Connection speed: 1 Gigabit per second (Gbps)
To avoid possible eye injury, do not look into an operating fiber-optic
module’s connectors.
3.1.2.1 Transceiver Installation
Use the following steps to install a transceiver.
1Insert the transceiver into the slot with the exposed section of PCB board facing down.
Figure 18 Transceiver Installation Example
2Press the transceiver firmly until it clicks into place.

3.2.1 Power Connection
Make sure you are using the correct power source and that no objects obstruct the airflow of the
fans.
The Switch uses two power supply modules, one of which is redundant, so if one power module fails
the system can operate on the remaining module.
Rear Panel Power Connection
Connect one end of the supplied power cord or power adaptor to the power receptacle on the back
of the Switch and the other end to the appropriate power source.
For Switches with a power switch (see Table 1 on page 15), use the POWER ON/OFF switch to
have the Switch power on or off.
Connecting the Power
Use the following procedures to connect the Switch to a power source after you have installed it in
a rack.
Note: Use the included power cord for the AC power connection.
1Connect the female end of the power cord to the AC power socket.
2Connect the other end of the cord to a power outlet.

8.3 PoE
Note: The PoE function and the following screens are available for models ending in “HP”
only.
The Switch supports both the IEEE 802.3af P ower over Ethernet (PoE) and IEEE 802.3at High Power
over Ethernet (PoE) standards. The Switch is Power Sourcing Equipment (PSE) because it provides
a source of power via its Ethernet ports, and each device that receives power through an Ethernet
port is a Powered Device (PD).
In the figure below, the IP camer a and IP phone get their power directly from the Switch. Aside
from minimizing the need for cables and wires, PoE removes the hassle of trying to find a nearby
electric outlet to power up devices.
Figure 53 Powered Device Examples
You can also set priorities so that the Switch is able to reserve and allocate power to certain PDs.
Note: The PoE devices t h at su pp l y or receive power and their connected Ethernet cables
must all be completely indoors.
To view the current amount of power that PDs are receiving from the Switch, click Monitor > Port

This section shows you the storm control feature.
Storm control limits the number of broadcast, multicast and unicast packets the S witch receives per
second on the ports. When the maximum number of allowable broadcast, multicast and/or unicast
packets is reached per second, the subsequent packets are discarded. Enabling this feature reduces

CHAPTER 9
Monitor: VLAN
9.1 Overview
This section provides information for VLAN in Monitor.
A VLAN (Virtual Local Area Network) allows a ph ysical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same
group(s); the traffic must first go through a router.
In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security among the
subscribers. When properly configured, VLAN prevents one subscriber from accessing the network
resources of another on the same LAN, thus a user will not see the printers and hard disks of
another user on the same network.
VLAN also increases network performance by limiting broadcasts to a smaller and more
manageable logical broadcast domain. In traditional switched environments, all broadcast packets
go to each and every individual port. With VLAN, all broadcasts are confined to a specific broadcast
domain.
9.1.1 What You Can Do in this Chapter
•The VLAN screen (Section 9.2 on page 62) displays VLAN, port, and VLAN port settings.
•The Guest VLAN screen (Section 9.3 on page 65) displays the global and port settings of the

Chapter 9 Monitor: VLAN
GS1900 Series User’s Guide
64
9.2.3 VLAN Port
Port -based VLANs are VLANs where the packet forwarding decision is based on the destination MAC
address and its associated port. Po rt-based VLANs require allowed outgoing ports to be defined for
each port. Therefore, if you wish to allow two subscriber ports to talk to each other, for example,
between conference rooms in a hotel, you must define the egress (an egress port is an outgoing
port, that is, a port through which a data packet leaves) for both ports. Port-based VLANs are
specific only to the Switch on which they were created.

be dropped.
Ingress Filter If set, the Switch discards incoming frames for VLANs that do not have this port as a
member.
VLAN Trunks Enable VLAN Trunking on ports connected to other switches or routers (but not ports
directly connected to end users) to allow frames belonging to unknown VLAN groups to

9.3 Guest VLAN
When 802.1x port authentication is enabled on the Switch and its ports, clients that do not have the
correct credentials are blocked from using the port(s). You can configure your Switch to have one
VLAN that acts as a guest VLAN. If you enable the guest VLAN (102 in the example) on a port (2 in
the example), the user (A in the example) that is not IEEE 802.1x capable or fails to enter the
correct username and password can still access the port, but traffic from the user is forwarded to
the guest VLAN. That is, unauthenticated users can ha ve access to limited network resources in the
same guest VLAN, such as the Internet. The rights gr anted to the Gu est VLAN depends on how the
network administrator configures switches or routers with the guest network feature.

CHAPTER 10
Monitor: MAC Table
10.1 Overview
This section provides information for MAC Table in Monitor.
The MAC Table screen (a MAC table is also known as a filtering database) shows how frames are
forwarded or filtered across the Switch’ s ports. When a device (which may belong to a VLAN group)
sends a packet which is forw arded to a port on th e S witch, the MAC address of the device is shown
on the Switch’s MAC Table. It also shows whether the MAC address is dynamic (learned by the
Switch) or static (manually entered in the Static MAC Forwarding screen).
The Switch uses the MAC Table to determine how to forward frames. See the following figure.
1The Switch examines a received frame and learns the port from which this source MAC address
came.
2The Switch checks to see if the frame's destination MAC address matches a source MAC address
already learned in the MAC Table.
• If the Switch has already learned the port for this MAC address, then it forwards the frame to
that port.
• If the Switch has not already learned the port for this MAC address, then the frame is flooded to
all ports. Too much port flooding leads to network congestion.
• If the Switch has already learned the port for this MAC address, but the destination port is the
same as the port it came in on, then it filters the frame.

CHAPTER 11
Monitor: Link Aggregation
11.1 Overview
This section provides information for Link Aggreg ation in Monitor.
Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity link.
You may want to trunk ports if for example, it is cheaper to use multiple lower-speed links than to
under-utilize a high-speed, but more costly, single-port link. However, the more ports you
aggregate then the fewer available ports you have. A trunk group is one logical link containing
multiple ports.
The Switch supports both static and dynamic link aggregation.
Note: In a properly planned network, it is recommended to implement static link
aggregation only. This ensures increased network stability and control over the
trunk groups on your Switch.

CHAPTER 12
Monitor: Loop Guard
12.1 Overview
This section provides information for Loop Guard in Monitor.
Loop guard is designed to handle loop problems on the edge of your network. This can occur when
a port is connected to a Switch that is in a loop state. Loop state occurs as a result of human error.
It happens when two ports on a switch are connected with the same cable. When a switch in loop
state sends out broadcast messages the messages loop back to the switch and are re-broadcast
again and again causing a broadcast storm.
If a switch (not in loop state) connects to a switch in loop state, then it will be affected by the
switch in loop state in the following way:
• It will receive broadcast messages sent out from the switch in loop state.
• It will receive its own broadcast messages that it sends out as they loop back. It will then re-
broadcast those messages again.
The following figure shows port N on switch A connected to switch B. Switch B is in loop state.
When broadcast or multicast packets leave port N and reach switch B, they are sent back to port N
on A as they are rebroadcast from B.
Figure 66 Switch in Loop State
The loop guard feature checks to see if a loop guard enabled port is connected to a switch in loop
state. This is accomplished by periodically sending a probe packet and seeing if the packet returns
on the same port. If this is the case, the Switch will shut down the port connected to the switch in
loop state.
The following figure shows a loop guard enabled port N on switch A sending a probe packet P to
switch B. Since switch B is in loop state, the probe packet P returns to port N on A. The Switch
then shuts down port N to ensure that the rest of the network is not affected by the switch in loop
state.

The Switch also shuts down port N if the probe packet returns to switch A on any other port. In
other words loop guard also protects against standard network loops. The following figure
illustrates three switches forming a loop. A sample path of the loop guard probe packet is also
shown. In this example, the probe packet is sent from port N and returns on another port. As long
as loop guard is enabled on port N. The Switch will shut down port N if it detects that the probe
packet has returned to the Switch.

Traditionally , IP packets are tr ansmitted in one of either two ways - Unicast (1 sender to 1 recipient)
or Broadcast (1 sender to everybody on the network). Multicast delivers IP packets to just a group
of hosts on the network.
IGMP (Internet Group Management Protocol) is a network-layer protocol used to establish
membership in an IPv4 multicast group - it is not used to carry user data. Refer to RFC 1112, RFC
2236 and RFC 3376 for information on IGMP versions 1, 2 and 3 respectively.

14.2.5 STP Statistics
(R)STP detects and breaks netw ork loops and provides backup links between switches, bridges or
routers. It allows a Switch to interact with other (R)STP-compliant switches in your network to
ensure that only one path exists between any two stations on the network.
The Switch uses IEEE 802.1w RSTP (Rapid Spanning Tree Protocol) that allows faster convergence
of the spanning tree than STP (while also being backwards compatible with STP-only aware
bridges). In RSTP, topology change information is directly propagated throughout the network from
the device that generates the topology ch ange. In STP, a longer delay is required as the device that
causes a topology change first notifies the root bridge and then the root bridge notifies the
network. Both RSTP and STP flush unwanted learned addresses from the filtering database. In
RSTP, the port states are Discarding, Learning, and Forwarding.
Note: In this user’s guide, “STP” refers to both STP and RSTP.

Port security allows only packets with dynamically learned MAC addresses and/or configured static
MAC addresses to pass through a port on the Switch. The Switch can learn up to 8K MAC addresses
in total with no limit on individual ports; system total MAC address entry is 8K. Static MAC address
still can be configured when port security is enabled; the function of port security is concerned with
dynamic mac address learn action. When total MAC address entry is 8k, static MAC can't be
configured.

Power-Up This shows how the Switch provides power to the connected PD at power-up.
802.3af - the Switch follows the IEEE 802.3af Power over Ethernet standard to supply
power to the connected PDs during power-up.
Legacy - the Switch can provide power to the connected PDs that require high inrush
currents at power-up.
Pre-802.3at - the Switch initially offers power on the port according to the IEEE 802.3af
standard, and then switches to support the IEEE 802.3at standard within 75 milliseconds
after a PD is connected to the port. Select this option if the Switch is performing 2-event
Layer-1 classification (PoE+ hardware classification) or the connected PD is NOT performing
Layer 2 power classification using Link Layer Discover y Protocol (LLDP).
802.3at - the Switch supports the IEEE 802.3 at High Power over Ethernet standard and
can supply power of up to 30W per Ethernet port. IEEE 802.3at is also known as PoE + or
PoE Plus. An IEEE 802.3at compatible device is referred to as Type 2. Power Class 4 (High
Power) can only be used by Type 2 devices. If the connected PD requires a Class 4 current
when it is turned on, it will be powered up in this mode.
Wide Range
Detection This field is available on GS1900-8HP (Revision B1) and GS1900-10HP only.
This shows whether the Switch enables a wider detection range for the PD or not.
The Switch de tects whether a connected device is a powered device or not before supplying
power to the port. For the PD detection, the Switch applies a fixed voltage to the device and
then receives returned current. If the returned current is within the IEEE 802.3AF/AT
standard range, the device will be considered as a valid PD by the Switch.
However, in real cases, environmental interferences might easily cause the returned current
out of the standard r ange. This field displ ays Enable if the Switch applies a wider range for
PD detection. Otherwise, it displays Disable.
Consuming
Power (mW) Displays the current amount of power consumed by the PD from the Switch on this port.
Max Power
(mW) Displa ys the maximum amou nt of power the PD could use from the Swit ch on this port. The

standard range, the device will be considered as a valid PD by the Switch.
However, in real cases, environmental interferences might easily cause the returned current
out of the standard r ange. This field displ ays Enable if the Switch applies a wider range for
PD detection. Otherwise, it displays Disable.

CHAPTER 20
Configuration: VLAN
20.1 Overview
This section provides information for VLAN in Configuration.
A VLAN (Virtual Local Area Network) allows a ph ysical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same
group(s); the traffic must first go through a router.
In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security among the
subscribers. When properly configured, VLAN prevents one subscriber from accessing the network
resources of another on the same LAN, thus a user will not see the printers and hard disks of
another user on the same network.
VLAN also increases network performance by limiting broadcasts to a smaller and more
manageable logical broadcast domain. In traditional switched environments, all broadcast packets
go to each and every individual port. With VLAN, all broadcasts are confined to a specific broadcast
domain.
20.1.1 What You Can Do in this Chapter
• The VLAN screen (Section 20.2 on page 113) displays VLAN, port, and VLAN port settings.
• The Guest VLAN screen (Section 20.3 on page 118) displa ys the global and port settings of the

20.2.5 The VLAN Port Screen
Port -based VLANs are VLANs where the packet forwarding decision is based on the destination MAC
address and its associated port. Port-based VLANs require allowed outgoing ports to be defined for
each port. Therefore, if you wish to allow two subscriber ports to talk to each other, for example,
between conference rooms in a hotel, you must define the egress (an egress port is an outgoing
port, that is, a port through which a data packet leaves) for both ports. Port-based VLANs are
specific only to the Switch on which they were created.
Use this screen to view VLAN port settings. Click Configuration > VLAN > VLAN > VLAN Port to

20.3 Guest VLAN
When 802.1x port authentication is enabled on the Switch and its ports, clients that do not have the
correct credentials are blocked from using the port(s). You can configure your Switch to have one
VLAN that acts as a guest VLAN. If you enable the guest VLAN (102 in the example) on a port (2 in
the example), the user (A in the example) that is not IEEE 802.1x capable or fails to enter the
correct username and password can still access the port, but traffic from the user is forwarded to
the guest VLAN. That is, unauthenticated users can ha ve access to limited network resources in the
same guest VLAN, such as the Internet. The rights gr anted to the Gu est VLAN depends on how the
network administrator configures switches or routers with the guest network feature.

Configuration: Link Aggregation
22.1 Overview
This section provides information for Link Aggreg ation in Configuration.
This chapter shows you how to logically aggregate physical links to form one logical, higher

22.1.1 What You Can Do in this Chapter
The Link Aggregation screen (Section 22.2 on page 129) displays global, LAG management, LAG
port, and LACP port settings.
22.2 Link Aggregation
Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity link.
You may want to trunk ports if for example, it is cheaper to use multiple lower-speed links than to
under-utilize a high-speed, but more costly, single-port link.
However, the more ports you aggregate then the fewer available ports you have. A trunk group is
one logical link containing multiple ports.
The Switch supports both static and dynamic link aggregation.
Note: In a properly planned network, it is recommended to implement static link
aggregation only. This ensures increased network stability and control over the
trunk groups on your Switch.

LACP System
Priority LACP system priority is a number between 1 and 65,535. The switch with the lowest system
priority (and lowest port number if system priority is the same) becomes the LACP “server”.
The LACP “server” controls the operation of LACP setup. Enter a number to set the priority
of an active port using Link Aggregation Control Protocol (LACP). The smaller the number,
the higher the priority level.
Load Balance
Algorithm Select the outgoing traffic distribution type. Packets from the same source and/or to the
same destinati on are sent over the same link within the trunk. B y default, the Switch uses
the IP/MAC Address distribution type. If the Switch is behind a router, the packet’s
destination or source MAC address will be changed. In this case, set the Switc h to distribute
traffic based on its IP address to make sure port trunking can work properly.
Select MAC Address to distribute traffic based on a combination of the packet’s source and
destination MAC addresses.

23.1 Overview
This section provides information for Loop Guard in Configuration.
This chapter shows you how to configure the Switch to guard against loops on the edge of your
network.
23.2 Loop Guard
Loop guard allows you to configure the Switch to shut down a port if it detects that packets sent out
on that port loop back to the Switch. While you can use Spanning Tree Protocol (STP) to prevent
loops in the core of your network. STP cannot prevent loops that occur on the edge of your
network.

26.1 Overview
This section provides information for Spanning Tree in Configuration.
The Switch supports Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP) and
Multiple Spanning Tree Protocol (MSTP) as defined in the following standards.
• IEEE 802.1D Spanning Tree Protocol
• IEEE 802.1w Rapid Spanning Tree Protocol
• IEEE 802.1s Multiple Spanning Tree Protocol
The Switch also allows you to set up multiple STP configurations (or trees). Ports can then be
assigned to the trees.
26.2 Spanning Tree
(R)STP detects and breaks netw ork loops and provides backup links between switches, bridges or
routers. It allows a Switch to interact with other (R)STP-compliant switches in your network to
ensure that only one path exists between any two stations on the network.

Priority is part of bridge ID, used for CIST root bridge selection.
Max Hops Enter a maximum number of hops value. The value can be between 1 and 40.
Forward Delay This is the maximum time (in seconds) a switch will wait before changing states. This delay
is required because every switch must receive information about topology changes before it
starts to forward frames. In addition, each port needs time to listen for conflicting
information that would make it return to a blocking state; otherwise, temporary data loops
might result. The allowed range is 4 to 30 seconds.
As a general rule:
Note: 2 * (Forward Delay - 1) >= Max Age >= 2 * (Hello Time + 1)
Max Age This is the maximum time (in seconds) a switch can wait without receiving a BPDU before
attempting to reconfigure. All switch ports (except for designated ports) should receive
BPDUs at regular intervals. Any port that ages out STP information (provided in the last
BPDU) becomes the designated port for the attached LAN. If it is a root port, a new root
port is selected from among the switch ports attached to the network. The allowed r ange is
6 to 40 seconds.
Tx Hold Count Enter a transmission hold count value. The value can be between 1 and 10.

frame is transmitted to the neighboring units, signalling that the LLDP information isn't
valid anymore. Tx Reinit con trols the amount of seconds between the shutdown frame and
a new LLDP initial ization. Valid values are restricted to 1 - 10 seconds.
Transmit Delay Enter the transmission del ay value.
If some configurat ion is changed (e.g. the IP address) a new LLDP frame is tr ansmitted, but
the time between the LLDP frames will always be at least the value of Tx Delay seconds. Tx
Delay cannot be larger than 1/4 of the Tx Interval value. Valid values are restricted to 1 -
8192 seconds.
LLDP-MED Fast
Start Repeat
Count
Enter the LLDP-MED fast start repeat count value.
Because there is a risk of an LLDP frame being lost during transmission between neighbors,
it is recommended to repeat the fast start transmission multiple times to increase the
possibility of the neighbors receiving the LLDP frame. With Fast start repeat count it is
possible to specify the number of times the fast start transmission would be repeated. The
recommended value is 4 times, given that 4 LLDP frames with a 1 second interval will be
transmitted, when an LLDP frame with new i nformation is received.

Configuration: QoS
28.1 Overview
This section provides information for QoS (Quality of Service) in Configuration.
28.2 General
Quality of Service (QoS) refers to both a network's ability to deliver data with minimum delay, and
the networking methods used to control the use of bandwidth. Without QoS, all traffic data is
equally likely to be dropped when the network is congested. This can cause a reduction in network
performance and make the network inadequate for time-critical application such as video-on-
demand.

the DoS feature on the Switch and the port(s).
Table 148 DoS Attack Types
TYPE PACKET TYPE DESCRIPTION
DA_EQUAL_SA Layer 2 These attacks result from sending a speci a lly crafted packet
to a machine where the source MAC address is the same as
the destination MAC address. The system attempts to reply
to itself, resulting in system lockup.
LAND Layer 3 IPv4/IPv6 These attacks result from sending a specially crafted packet
to a machine where the source host IPv4/IPv6 address is the
same as the destination host IPv4/IPv6 address. The system
attempts to reply to itself, resulting in syst em lockup.
UDP_BLAT / TCP_BLAT
(Blat Attack) Layer 3 IPv4/IPv6 These attacks result from sending a specially crafted packet
to a machine where the source host UDP/TCP port is the
same as the destination host UDP/TCP port. The system
attempts to reply to itself, resulting in syst em lockup.
PoD (Ping of Death) Layer 3 IPv4/IPv6 Ping of Death uses a "ping" utility to create and send an IP
packet that exceeds th e maximum 65,536 bytes of data
allowed by the IP specification. This may cause systems t o
crash, hang or reboot.
IPv6_FRAG_LEN_MIN Layer 3 IPv6 This attack uses IPv6 fragmented packets (excluding the last
one) whose payload length is less than 1240 bytes.
ICMP_FRAG_PKT Layer 3 IPv4/IPv6 This attack uses many small fragmented ICMP p a ckets.
ICMPv4_PING_MAX /
ICMPv6_PING_MAX Layer 3 IPv4/IPv6 This attack uses Ping packets whose length is larger than
512 bytes.
SMURF Layer 3 IPv4 This attack uses Internet Control Message Protocol (ICMP)
echo requests packets (pings) to cause network congestion
or outages.
SYNchronization (SYN), ACKnowledgment (ACK) and FINish (FIN) packets are used to initiate, acknowledge
and conclude TCP/IP communication sessi o ns. The following scans exploit weaknesses in the TCP/IP
specification and try to illicit a response from a host to identify ports for an attack:
TCP_HDR_LEN_MIN Layer 3 IPv4 TCP packets with header length less than 20 bytes.
SYN_SPORT_LESS_1024 Layer 3 IPv4/IPv6 TCP SYN packets with source port less than 1024.
NULL_SCAN (Scan
Attack) Layer 3 IPv4/IPv6 TCP sequence number is zero and all control bits are zeroes.
XMAS (Scan Attack) Layer 3 IPv4/IPv6 TCP sequence number is zero and the FIN, URG and PSH bits
are set.
SYN_FIN Layer 3 IPv4/IPv6 SYN and FIN bits are set in the TCP packet.

Chapter 33 Troubleshooting
GS1900 Series User’s Guide
225
One of the LEDs does not behave as expected.
1Make sure you understand the normal behavior of the LED. See Section 3.3 on page 30.
2Check the hardware connections. See Chapter 2 on page 19.
3Inspect your cables for damage. Contact the vendor to replace any damaged cables.
4Turn the Switch off and on (in DC models or if the DC power supply is connected in AC/DC models).
5Disconnect and re-connect the power adaptor or cord to the Switch (in AC models or if the AC
power supply is connected in AC/DC models).
6If the problem continues, contact the vendor.
33.2 Switch Access and Login
I forgot the IP address for the Switch.
1The default in-band IP address is 192.168.1.1.
2Use the console port to log in to the Switch.
3Use the MGMT port to log in to the Switch, the default IP addr ess of the MGMT port is 192.168.0.1.
4If this does not work, you have to reset th e device to its factory defaults. See Section 32.6 on page
219.
I forgot the username and/or password.
1The default username is admin and the default password is 1234.
2If this does not work, you have to reset th e device to its factory defaults. See Section 32.6 on page
219.
I cannot see or access th e Login screen in the web configurator.
1Make sure you are using the correct IP address.
• The default in-band IP address is 192.168.1.1.
Chapter 33 Troubleshooting
GS1900 Series User’s Guide
226
• If you changed the IP address, use the new IP address.
• If you changed the IP address and hav e forgotten it, see the troubleshooting su ggestions for I
forgot the IP address for the Switch.
2Check the hardware connections, and make sure the LEDs are behaving as expected. See Section
on page 19.
3Make sure your Internet browser does not block pop-up windows and has JavaScripts and Java
enabled.
4Make sure your computer is in the same subnet as the Switch. (If you know that there are routers
between your computer and the Switch, skip this step.)
5Reset the device to its factory defaults, and try to access the Switch with the default IP address.
See Section 32.6 on page 219.
6If the problem continues, contact the vendor, or try one of the advanced suggestions.
Advanced Suggestions
• Try to access the Switch using another service, such as Telnet. If you can access the Switch,
check the remote management settings to find out why the Switch does not respond to HTTP.
I can see the Login screen, but I cannot log in to the Switch.
1Make sure you have entered the user name and password correctly. The default user name is
admin, and the default password is 1234. These fields are case-sensitive, so make sure [Caps
Lock] is not on.
2You may have exceeded the maximum number of concurrent Telnet sessions. Close other Telnet
session(s) or try connecting again later.
Check that you have enabled logins for HTTP or Telnet. If you have configured a secured client IP
address, your computer’s IP address must match it. Refer to the chapter on access control for
details.
3Disconnect and re-connect the cord to the Switch.
4If this does not work, you have to reset th e device to its factory defaults. See Section 32.6 on page
219.
Pop-up Windows, JavaScripts and Java Permissions
In order to use the web configurator you need to allow:
• Web browser pop-up windows from your device.
