Understanding the User Interfaces

The managed switch software includes a set of comprehensive management functions for

configuring and monitoring the system by using one of the following methods:

•Web user interface

•Simple Network Management Protocol (SNMP)

•Command-line interface (CLI)

Each of the standards-based management methods allows you to configure and monitor the

components of the managed switch software. The method you use to manage the system

depends on your network size and requirements, and on your preference.

The M4100 Series Managed Switch User Manual (this book) describes how to use the

web-based interface to manage and monitor the system.

Web Management Interface Overview

Your managed switch contains an embedded web server and management software for

managing and monitoring switch functions. The managed switch functions as a simple

switches without the management software. However, you can use the management

software to configure more advanced features that can improve switch efficiency and overall

network performance.

Web-based management lets you monitor, configure, and control your switch remotely using

a standard web browser instead of using expensive and complicated SNMP software

products. From your web browser, you can monitor the performance of your switch and

optimize its configuration for your network. You can configure all switch features, such as

VLANs, QoS, and ACLs, by using the web-based management interface.

Configure an IPv4 Management VLAN

For you to manage the device by using the web-based configuration utility, the device

management IP address must be defined and known. A management VLAN interface is

created by default and it is assigned an IP address if a DHCP server is present. If it fails to

get an IP address, a fallback address 169.254.100.100/255.255.0.0 is assigned to it.

Management VLAN is used as the default source interface for the syslog, message log, and

SNMP client, and so on The network interface is disabled by default.

The management VLAN is the logical interface used for in-band connectivity with the switch

through any of the switch’s front panel ports. The configuration parameters associated with

the switch’s management VLAN do not affect the configuration of the front panel ports

through which traffic is switched or routed.

To access the switch over a network, you must first configure it with IP information (IP

address, subnet mask). You can configure the IP information using any of the following:

•DHCP

•Terminal interface through the EIA-232 port.

View or Set the System Time

The managed switch software supports the Simple Network Time Protocol (SNTP). You can

also set the system time manually.

SNTP assures accurate network device clock time synchronization up to the millisecond.

T ime synchronization is performed by a network SNTP server. The managed switch software

operates only as an SNTP client and cannot provide time services to other systems.

Time sources are established by stratums. Stratums define the accuracy of the reference

clock. The higher the stratum (where zero is the highest), the more accurate the clock. The

device receives time from stratum 1 and above since it is itself a stratum 2 device.

The following is an example of stratums:

•Stratum 0. A real-time clock is used as the time source, for example, a GPS system.

•Stratum 1. A server that is directly linked to a stratum 0 time source is used. Stratum 1

time servers provide primary network time standards.

Configure System Information

M4100 Series Managed Switch

•Stratum 2. The time source is distanced from the stratum 1 server over a network path.

For example, a stratum 2 server receives the time over a network link, through NTP, from

a stratum 1 server.

Information received from SNTP servers is evaluated based on the time level and server

type.

SNTP time definitions are assessed and determined by the following time levels:

•T1. Time that the original request was sent by the client.

•T2. Time that the original request was received by the server.

•T3. Time that the server sent a reply.

•T4. Time that the client received the server's reply.

The device can poll unicast server types for the server time.

Polling for unicast information is used for polling a server for which the IP address is known.

SNTP servers that were configured on the device are the only ones that are polled for

synchronization information. T1 through T4 are used to determine server time. This is the

preferred method for synchronizing device time because it is the most secure method. If this

method is selected, SNTP information is accepted only from SNTP servers defined on the

device using the SNTP Server Configuration screen.

The device retrieves synchronization information, either by actively requesting information or

at every poll interval.

Configure SNTP Global Settings

You can view and adjust date and time settings. SNTP stands for Simple Network Time

Protocol. As its name suggests, it is a less complicated version of Network Time Protocol,

that is a system for synchronizing the clocks of networked computer systems, primarily when

data transfer is handled through the Internet.

To configure SNTP global settings:

1. Prepare your computer with a static IP address in the 169.254.100.0 subnet, for

example, 169.254.100.201.

2. Connect an Ethernet cable from an Ethernet port on your computer to an Ethernet port on

The System Information screen displays.

8. Select System  Management > Time  Time Configuration, and select SNTP as the

Clock Source.

9. Use Client Mode to specify the mode of operation of SNTP Client.

An SNTP client can operate in one of the following modes:

•Disable. SNTP is not operational. No SNTP requests are sent from the client nor are

any received SNTP messages processed.

•Unicast. SNTP operates in a point-to-point fashion. A unicast client sends a request

to a designated server at its unicast address and expects a reply from which it can

determine the time and, optionally, the round-trip delay and local clock offset relative

to the server.

•Broadcast. SNTP operates in the same manner as multicast mode but uses a local

broadcast address instead of a multicast address. The broadcast address was a

single subnet scope while a multicast address has Internet wide scope.

The default value is Disable.

10. Use Port to specify the local UDP port to listen for responses or broadcasts.

The allowed range is 1 to 65535. The default value is 123.

11. Specify the Source Interface to be used for SNTP Client.

Possible values are as follows:

•Routing interface

•Routing VLAN

Configure System Information

M4100 Series Managed Switch

•Routing loopback interface

By default, VLAN 1 is used as the source interface.

12. Use Unicast Poll Interval to specify the number of seconds between unicast poll requests

expressed as a power of two when configured in unicast mode.

The allowed range is 6 to 10. The default value is 6.

13. Use Broadcast Poll Interval to specify the number of seconds between broadcast poll

requests expressed as a power of two when configured in broadcast mode.

Broadcasts received prior to the expiry of this interval are discarded. The allowed range is

6 to 10. The default value is 6.

14. Use Unicast Poll Timeout to specify the number of seconds to wait for an SNTP response

when configured in unicast mode.

The allowed range is 1 to 30. The default value is 5.

15. Use Unicast Poll Retry to specify the number of times to retry a request to an SNTP server

after the first time-out before attempting to use the next configured server when configured in

unicast mode.

The allowed range is 0 to 10. The default value is 1.

When using SNTP/NTP time servers to update the switch's clock, the time data received

from the server is based on Coordinated Universal Time (UTC), that is the same as

Greenwich Mean Time (GMT). This cannot be the time zone in which the switch is

located.

16. Use Time Zone Name to specify the time zone name.

The time zone can affect the display of the current system time. The default value is UTC.

17. Use Offset Hours to specify the number of hours difference from UTC. You can configure a

time zone specifying the number of offset hours and optionally the number of offset minutes

that the switch’s time zone is different from UTC.

The allowed range is -24 to 24. The default value is 0.

18. Use Offset Minutes to specify the number of minutes that the switch’s time zone is different

from UTC.

The allowed range is 0 to 59. The default value is 0.

LLDP Overview

The IEEE 802.1AB-defined standard, Link Layer Discovery Protocol (LLDP), allows stations

on an 802 LAN to advertise major capabilities and physical descriptions. This information is

viewed by a network manager to identify system topology and detect bad configurations on

the LAN.

LLDP is a one-way protocol; there are no request/response sequences. Information is

advertised by stations implementing the transmit function, and is received and processed by

stations implementing the receive function. The transmit and receive functions can be

enabled or disabled separately per port. By default, both transmit and receive are disabled on

all ports. The application is responsible for starting each transmit and receive state machine

appropriately, based on the configured status and operational state of the port.

The Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) is an

enhancement to LLDP with the following features:

•Auto-discovery of LAN policies such as VLAN, Layer 2 Priority, and DiffServ settings,

enabling plug and play networking.

•Device location discovery for creation of location databases.

•Extended and automated power management of Power over Ethernet endpoints.

•Inventory management, enabling network administrators to track their network devices

and determine their characteristics (manufacturer , software and hardware versions, serial

or asset number).

VLAN Overview

Adding Virtual LAN (VLAN) support to a Layer 2 switch offers some of the benefits of both

bridging and routing. Like a bridge, a VLAN switch forwards traffic based on the Layer 2

header, which is fast, and like a router, it partitions the network into logical segments, which

provides better administration, security, and management of multicast traffic.

By default, all ports on the switch are in the same broadcast domain. VLANs electronically

separate ports on the same switch into separate broadcast domains so that broadcast

packets are not sent to all the ports on a single switch. When you use a VLAN, users can be

grouped by logical function instead of physical location.

Each VLAN in a network has an associated VLAN ID, which appears in the IEEE 802.1Q tag

in the Layer 2 header of packets transmitted on a VLAN. An end station can omit the tag, or

the VLAN portion of the tag, in which case the first switch port to receive the packet can either

reject it or insert a tag using its default VLAN ID. A given port can handle traffic for more than

one VLAN, but it can support only one default VLAN ID.

Configure a Basic VLAN

You can define VLAN groups stored in the VLAN membership table. Each switch in the

managed switch family supports up to 1024 VLANs. Two VLANs are created by default,

VLAN 1 and VLAN 2:

•VLAN 1 is the default VLAN of which all ports are members.

•VLAN 2 is the default Auto VoIP VLAN.

To configure a basic VLAN:

1. Prepare your computer with a static IP address in the 169.254.100.0 subnet, for

example, 169.254.100.201.

2. Connect an Ethernet cable from an Ethernet port on your computer to an Ethernet port on

the switch.

3. Launch a web browser.

accepted and assigned the value of the Port VLAN ID for this port. With either option,

VLAN tagged frames are forwarded in accordance to the 802.1Q VLAN specification.

13. Specify the Ingress Filtering setting:

•When enabled, the frame is discarded if this port is not a member of the VLAN with

which this frame is associated. In a tagged frame, the VLAN is identified by the VLAN

ID in the tag. In an untagged frame, the VLAN is the port VLAN ID specified for the

port that received this frame.

•When disabled, all frames are forwarded in accordance with the 802.1Q VLAN bridge

specification. The factory default is disabled.

14. Use Port Priority to specify the default 802.1p priority assigned to untagged packets arriving

Configure a MAC-Based VLAN Group

The MAC-based VLAN feature allows incoming untagged packets to be assigned to a VLAN

and thus classifies traffic based on the source MAC address of the packet.

You define MAC to VLAN mapping by configuring an entry in the MAC to VLAN table. An

entry is specified through a source MAC address and the desired VLAN ID. The MAC to

VLAN configurations are shared across all ports of the device (for example, system-wide

table has MAC address to VLAN ID mappings).

When untagged or priority tagged packets arrive at the switch and entries exist in the MAC to

VLAN table, the source MAC address of the packet is looked up. If an entry is found, the

corresponding VLAN ID is assigned to the packet. If the packet is already priority tagged, it

maintains this value; otherwise the priority is set to zero. The assigned VLAN ID is verified

against the VLAN table. If the VLAN is valid ingress processing on the packet continues;

otherwise, the packet is dropped. This implies that the user is allowed to configure a MAC

address mapping to a VLAN that has not been created on the system.

Configure a MAC-based VLAN group:

1. Prepare your computer with a static IP address in the 169.254.100.0 subnet, for

example, 169.254.100.201.

2. Connect an Ethernet cable from an Ethernet port on your computer to an Ethernet port on

the switch.

Configure a Protocol-Based VLAN Group

You can use a protocol-based VLAN to define filtering criteria for untagged packets. By

default, if you do not configure any port- (IEEE 802.1Q) or protocol-based VLANs, untagged

packets are assigned to VLAN 1. You can override this behavior by defining either port-based

VLANs or protocol-based VLANs, or both. Tagged packets are always handled according to

the IEEE 802.1Q standard, and are not included in protocol-based VLANs.

If you assign a port to a protocol-based VLAN for a specific protocol, untagged frames

received on that port for that protocol are assigned the protocol-based VLAN ID. Untagged

frames received on the port for other protocols are assigned the Port VLAN ID, either the

default PVID (1) or a PVID that you specifically assigned to the port using the Port VLAN

Configuration screen.

You define a protocol-based VLAN by creating a group. Each group has a one-to-one

relationship with a VLAN ID, can include one to three protocol definitions, and can include

multiple ports. When you create a group, you choose a name and a Group ID is assigned

automatically.

To configure a protocol-based VLAN group:

1. Prepare your computer with a static IP address in the 169.254.100.0 subnet, for

maps network layer addresses to physical medium access control (MAC) addresses.

•IPX. The Internetwork Packet Exchange (IPX) is a connectionless datagram

network-layer protocol that forwards data over a network.

10. Use VLAN ID to select the VLAN ID.

It can be any number in the range of 1 to 4093. All the ports in the group assign this VLAN

Spanning Tree Protocol Overview

The Spanning Tree Protocol (STP) provides a tree topology for any arrangement of bridges.

STP also provides one path between end stations on a network, eliminating loops. Spanning

tree versions supported include Common STP, Multiple STP, and Rapid STP.

Classic STP provides a single path between end stations, avoiding and eliminating loops. For

information about configuring Common STP, see Configure CST Ports on page 152.

Multiple Spanning Tree Protocol (MSTP) supports multiple instances of Spanning Tree to

efficiently channel VLAN traffic over different interfaces. Each instance of the Spanning Tree

behaves in the manner specified in IEEE 802.1w, Rapid Spanning Tree (RSTP), with slight

Configure Switching Information

146

M4100 Series Managed Switch

modifications in the working but not the end effect (chief among the effects is the rapid

transitioning of the port to Forwarding). The difference between the RSTP and the traditional

STP (IEEE 802.1D) is the ability to configure and recognize full-duplex connectivity and ports

that are connected to end stations, resulting in rapid transitioning of the port to Forwarding

state and the suppression of Topology Change Notification. These features are represented

by the parameters pointtopoint and edgeport. MSTP is compatible with both RSTP and STP.

It behaves appropriately to STP and RSTP bridges. A MSTP bridge can be configured to

behave entirely as a RSTP bridge or an STP bridge.

Note: For two bridges to be in the same region, the force version should be

802.1s and their configuration name, digest key, and revision level

should match. For additional information about regions and their effect

on network topology, refer to the IEEE 802.1Q standard.

IGMP Snooping Overview

Internet Group Management Protocol (IGMP) snooping is a feature that allows a switch to

forward multicast traffic intelligently on the switch. Multicast IP traffic is traffic that is destined

to a host group. Host groups are identified by class D IP addresses, which range from

224.0.0.0 to 239.255.255.255. Based on the IGMP query and report messages, the switch

forwards traffic only to the ports that request the multicast traffic. This prevents the switch

from broadcasting the traffic to all ports and possibly affecting network performance.

A traditional Ethernet network can be separated into different network segments to prevent

placing too many devices onto the same shared media. Bridges and switches connect these

segments. When a packet with a broadcast or multicast destination address is received, the

switch forwards a copy into each of the remaining network segments in accordance with the

IEEE MAC Bridge standard. Eventually, the packet is made accessible to all nodes

connected to the network.

This approach works well for broadcast packets that are intended to be seen or processed by

all connected nodes. In the case of multicast packets, however, this approach could lead to

less efficient use of network bandwidth, particularly when the packet is intended for only a

small number of nodes. Packets are flooded into network segments where no node has any

interest in receiving the packet. While nodes rarely incur any processing overhead to filter

packets addressed to unrequested group addresses, they are unable to transmit new

packets onto the shared media for the period of time that the multicast packet is flooded. The

problem of wasting bandwidth is even worse when the LAN segment is not shared, for

example, in full-duplex links.

Allowing switches to snoop IGMP packets is a creative effort to solve this problem. The

switch uses the information in the IGMP packets as they are being forwarded throughout the

network to determine which segments should receive packets directed to the group address.

on the network to announce their multicast memberships. This central device is the IGMP

querier. The IGMP query responses, known as IGMP reports, keep the switch updated with

the current multicast group membership on a port-by-port basis. If the switch does not

receive updated membership information in a timely fashion, it stops forwarding multicasts to

the port where the end device is located.

Link Aggregation Group Overview

Link aggregation groups (LAGs), which are also known as port channels, allow you to

combine multiple full-duplex Ethernet links into a single logical link. Network devices treat the

aggregation as if it were a single link, which increases fault tolerance and provides load

sharing. You assign the LAG VLAN membership after you create a LAG. The LAG by default

becomes a member of the management VLAN.

A LAG interface can be either static or dynamic, but not both. All members of a LAG must

participate in the same protocols. A static port channel interface does not require a partner

system to be able to aggregate its member ports.

Static LAGs are supported. When a port is added to a LAG as a static member, it neither

transmits nor receives LACPDUs.

Configure LAG Settings

You can use LAGs to group one or more full-duplex Ethernet links to be aggregated together

to form a link aggregation group, which is also known as a port channel. The switch treats the

LAG as if it were a single link.

To configure LAG settings:

1. Prepare your computer with a static IP address in the 169.254.100.0 subnet, for

example, 169.254.100.201.

2. Connect an Ethernet cable from an Ethernet port on your computer to an Ethernet port on

9. Use the list to enable or disable Admin Mode.

When the LAG is disabled, no traffic flows and LACPDUs is dropped, but the links that

form the LAG are not released. The default is enable.

10. Use Hash Mode to select the load-balancing mode used on a port channel (LAG).

Traffic is balanced on a port channel (LAG) by selecting one of the links in the channel

over which to transmit specific packets. The switch selects the link by creating a binary

pattern from selected fields in a packet, and associating that pattern with a particular link:

•Src MAC, VLAN, EType,i ncoming port — Source MAC, VLAN, EtherType, and

incoming port associated with the packet.

•Dest MAC, VLAN, EType, incoming port — Destination MAC, VLAN, EtherType, and

incoming port associated with the packet.

•Src/Dest MAC, VLAN, EType, incoming port — Source/Destination MAC, VLAN,

EtherType, and incoming port associated with the packet.

•Src IP and Src TCP/UDP Port — Source IP and Source TCP/UDP fields of the packet.

•Dest IP and Dest TCP/UDP Port — Destination IP and Destination TCP/UDP Port

fields of the packet.

•Src/Dest IP and TCP/UDP Port — Source/Destination IP and source/destination

TCP/UDP Port fields of the packet.

•Enhanced hashing mode — Features MODULO-N operation based on the number

of ports in the LAG, non-unicast traffic and unicast traffic hashing using a common

hash algorithm, excellent load balancing performance, and packet attributes selection

based on the packet type:

•For L2 packets, source and destination MAC address are used for hash

Configure Route Preferences

Use this panel to configure the default preference for each protocol, such as 60 for static

routes, 120 for RIP. These values are arbitrary values in the range of 1 to 255 and are

independent of route metrics. Most routing protocols use a route metric to determine the

shortest path known to the protocol, independent of any other protocol.

The best route to a destination is chosen by selecting the route with the lowest preference

value. When there are multiple routes to a destination, the preference values are used to

determine the preferred route. If there is still a tie, the route with the best route metric is

chosen. To avoid problems with mismatched metrics (for example, RIP and OSPF metrics

are not directly comparable), you must configure different preference values for each of the

protocols.

To configure route preferences:

1. Prepare your computer with a static IP address in the 169.254.100.0 subnet, for

example, 169.254.100.201.

IpInAddrErrors The number of input datagrams discarded because the IP address in

their IP header's destination field was not a valid address to be

received at this entity. This count includes invalid addresses (such as

0.0.0.0) and addresses of unsupported classes (such as Class E). For

entities that are not IP gateways and therefore do not forward

datagrams, this counter includes datagrams discarded because the

destination address was not a local address.

IpForwDatagrams The number of input datagrams for which this entity was not their final

IP destination, as a result of which an attempt was made to find a route

to forward them to that final destination. In entities that do not act as IP

gateways, this counter includes only those packets that were

source-routed through this entity, and the source-route option

processing was successful.

IpInUnknownProtos The number of locally addressed datagrams received successfully but

discarded because of an unknown or unsupported protocol.

IpInDiscards The number of input IP datagrams for which no problems were

encountered to prevent their continued processing, but that were

discarded (such as for lack of buffer space). Note that this counter does

not include any datagrams discarded while awaiting re-assembly.

IpInDelivers The total number of input datagrams successfully delivered to IP user

protocols (including ICMP).

ICMP) supplied to IP in requests for transmission. This counter does

not include any datagrams counted in ipForwDatagrams.

IpOutDiscards The number of output IP datagrams for which no problem was

encountered to prevent their transmission to their destination, but that

were discarded (such as, for lack of buffer space). This counter

includes datagrams counted in ipForwDatagrams if any such packets

met this (discretionary) discard criterion.

IpOutNoRoutes The number of IP datagrams discarded because no route could be

found to transmit them to their destination. Note that this counter

includes any packets counted in ipForwDatagrams that meet this

`no-route' criterion. This includes any datagrams that a host cannot

route because all of its default gateways are down.

IpReasmTimeout The maximum number of seconds that received fragments are held

while they are awaiting reassembly at this entity.

IpReasmReqds The number of IP fragments received that needed to be reassembled at

this entity.

IpReasmOKs The number of IP datagrams successfully re-assembled.

IpReasmFails The number of failures detected by the IP re-assembly algorithm (for

whatever reason: timed out, errors, and so on). This is not necessarily

a count of discarded IP fragments since some algorithms can lose track

of the number of fragments by combining them as they are received.

IpFragOKs The number of IP datagrams that were successfully fragmented at this

entity.

IpFragFails The number of IP datagrams that were discarded because they needed

to be fragmented at this entity but could not be, such as because their

Don't Fragment flag was set.

Note that this counter includes all those counted by icmpOutErrors.

IcmpOutErrors The number of ICMP messages that this entity did not send due to

problems discovered within ICMP, such as a lack of buffers. This value

does not include errors discovered outside the ICMP layer, such as the

inability of IP to route the resultant datagram. In some implementations

there can be no types of error that contribute to this counter's value.

IcmpOutDestUnreachs The number of ICMP Destination Unreachable messages sent.
