Introduction

About the SmartSwitch 6000 and Matrix E7 families; how to use this guide; related guides; getting
help.

Welcome to the Element Manager for the SmartSwitch 6000 and Matrix E7 Modules
User’s Guide. This guide is a reference for using NetSight Element Manager for the
SmartSwitch 6000 and Matrix E7 products. The SmartSwitch 6000 and Matrix E7
products encompass the 6C105 chassis (for the 6000) and 6C107 chassis (for the Matrix
E7), as well as the SmartSwitch 6000 and Matrix E7 series modules.

The 6C105 SmartSwitch chassis is a stand-alone chassis. It offers five slots for interface
modules; it also has two slots for dual redundant power supplies (installed vertically to the
right of the module slots), and a removable fan tray (installed horizontally across the
bottom the chassis).

NOTE

The 6C107 Matrix E7 chassis is also a stand-alone chassis. It offers seven slots for
interface modules; it has a removable fan tray (installed underneath the module slots); it
also has two slots for dual redundant power supplies (installed across the bottom of the
chassis).

For Matrix E7 users: Modules for the Matr ix E7 (6C107) chassis are third generation

(6x3xx) boards. Third generation boards are fully supported in any of the 6C107 chassis’
seven slots. Second generation boards (6x2xx SmartSwitch modules) are fully supported
in slots 1-5 in the 6C107 chassis. A second generation board in slot 6 or 7 of the 6C107
will act as a standalone module.

The SmartSwitch 6000 Frame Transfer Matrix (FTM) backplane and Matrix E7 nTERA

backplane provide distributed processing po wer. The backplane’s passive design provides
a separate independent backplane connection from each module in the chassis to every
other module installed in the chassis; each module contains its own active switching
components (so switching horsepower increases with module density), and each module
can be managed independently (via its Module Manager management component) or —
for devices which support distributed management — as part of the chassis unit.

1-1

Introduction

The SmartSwitch 6000 and Matrix E7 modules include:

•The 6E122-26 and 6E123-26 SmartSwitch modules each provide 24 fixed 10Base-T

switch ports (via RJ45 connect ors on the 6 E122; RJ21 T elco connectors on t he 6E123)
and two slots for optional FE-100xx Fast Ethernet Port Interface Modules (FEPIMs).
Several Fast Ethernet port modules are available:

- the FE-100FX, which provides one multi-mode fiber port via an SC connector;

- the FE-100TX, with one Category 5 UTP RJ45 connector;

- the FE-100F3, with one single-mode fiber port via an SC connector;

- and the FE-100S1, S3, and S5, which prov ide one mult i-mode fib er , singl e-mode

fiber, or long reach single-mode fiber SONET/SDH port, all via SC connectors.

•The 6E132-25 and 6E133-25 SmartSwitch modules each provide 24 fixed 10Base-T

switch ports (also via R J45 fo r the 6E 132 and RJ2 1 for t he 6E133 ) and one s lot for an
optional High Speed Interface Module (HSIM) that can link the chassis to an FDDI,
ATM, WAN, or Gigabit Ethernet backbone. Each HSIM provides frame translation
between ATM, FDDI, WAN, Gigabit Ethernet, and Ethernet through an on-board Intel
i960 processor:

- The HSIM-F6 is an FDDI/Ethernet Translator , which can act as a Single Attached

Station (SAS) or Dual Attached Station (DAS) on an external FDDI ring.
Enterasys’ FDDI Port Interface Modules ( FPIMs) pro vide a wide rang e of med ia
connectivity to the ring. The HSIM-F6 also has full-duplex capability, allowing
for a 200 Mbps connection to another HSIM-F6.

- The HSIM-A6DP is an Asynchronous Transfer Mode (ATM) HSIM, which

provides an ATM uplink via two media-configurable ATM Port Interface
Modules (APIMs). The dual APIM design allows for a redundant connection to
the uplink, so that if the primary interface fails, the secondary interface will
automatically take over. The HSIM-A6DP acts as an ATM Forum LAN
Emulation Client (LEC) so that it can transfer data between devices on an 802.x
LAN supported by the SmartSwitch 6000 and Matrix E7 and ATM-connected end
stations across a high speed ATM Link. The HSIM-A6DP adheres to the ATM
Forum-approved LAN Emulation (LANE) standard, which defines how end users
that rely on existing data communications technology and protocols can operate
over an ATM network without penalty.

- The HSIM-W6 and HSIM-W84 are Wide Area Networking (WAN) HSIMs,

which can provide uplinks to WAN backbones and allow you to perform seamless
LAN to WAN switching. The HSIM-W6 support s IP and IPX bridg ing or rout ing
services, including IP RIP. Multiple WAN connectivity options are supported,
including Sync, T1, E1, D&I, ISDN S/T , DDS, and HDSL interfaces, through the
use of two configurable WAN Physical Interface Modules (WPIMs).
Connectivity is available for Point to Point Protocol (PPP), as well as Frame Relay
and Leased Lines. Each WPIM can act independently, allowing simultaneous
communication, or configured to provide redundant channels if desired. The
HSIM-W84 provides a fixed configuration of four RJ45 ports for four active T1
interfaces.

1-2

NOTE

Introduction

The HSIM-W6 and HSIM-W84 are intelligent devices that are functionally identical to the
CSX400. These HSIMs require their own IP addresses, and are managed as individual
devices rather than as part of the device in which they ar e installed. R efer to the CSX200
and CSX400 User’s Guide for details on managing these devices using NetSight Element
Manager.

- The HSIM-W87 is a Wide Area Network (WAN) HSIM that provides LAN to

WAN connectivity for any SmartSwitch that supports high-speed interface

modules (HSIMs). The HSIM-W87 has a DS3 interface (T3), providing up to 28

separate DS1 connections (T1). Refer to Chapter 8, HSIM-W87 Configuration,

for information on configuring an HSIM-W87.

- The HSIM-G01 and HSIM-G09 are Gigabit Ethernet HSIMs, each of which

provide a single Gigabit Ethernet connection that fully conforms to the IEEE

P802.3z (D3.1) Draft Standard. The HSIM-G01 provides a single 1000Base-SX

(short-wave) multimode fiber optic SC interface, allowing for link distances of up

to 500 meters. The HSIM-G09 provides a single 1000Base-LX (long-wave)

single mode/multimode fiber optic SC interface, allowing for link distances of up

to 3 kilometers.

- The HSIM-SSA710/20 are Wide Area Networking (WAN) HSIMs that support

up to two ISDN PRI interfaces with up to 24 V.90 56K modem connections.

The HSIM-SSA710/20 are intelligent devices that are managed as individual

devices rather than as part of the device in which they are installed. Before you

can access the device, you must add it to your central node database by inserting

it in an existing List, Tr ee, or Map View, or by doing a Discover p rocess (r efer to

your User’s Guide for more information). Once it has been added to your List,

Tree, or Map view, you can access and manage the HSIM according to the

information in Chapter 2, The Device View.

Introduction

•The 6M146-04 SmartSwitch carrier modul e provides t wo FEPIM slots an d two HSIM

slots.

Each of these SmartSwitch modules provide key mission-critical features such as
redundant links for load sharing, alarm thresholding, broadcast storm control, port
redirecting for traffic analysis, traffic priority configuration, and full error breakdown.
Per-port RMON support is also provided. By default, these modules perform traditional
switching (or bridging); each can also be configured to perform prestandard IEEE 8 02.1 Q
VLAN switching (a.k.a “port-based VL AN” switching) or Enterasys’ SecureFast
switching (activated via Local Management).

The 6C105 SmartSwitch 6000 and 6C107 Matrix E7 chassis themselves offer the
following features:

• Slots for up to 5 (for the 6C105) and 7 (for the 6C107) double-wide 2.4" interface
modules. Each interface module is individually driven and managed by on-board
processors, including an onboard SmartSwitch ASIC processor fo r switching, and Intel
i960 Host microprocessors for dedicated module management.

• A Frame Transfer Matrix (FTM) backplane design, that provides a separate
independent backplane connection from each module in the chassis to every other
module installed in the chassis. This allows a backplane bandwidth capacity of up to

3.2 Gbps.

• Support for redundant, load-sharing power supplies to provide fault tolerance.

• Enterasys’ LANVIEW Diagnostic LEDs for quick visual diagnosis of interface and
device performance; a single removable fan tray; a 19" footprint for ease of installation
in rack mounts; and front panel accessibility to all chassis components for easy
maintenance.

Using the SmartSwitch 6000 and Matrix E7 User’s Guide

Each chapter in this guide describes one major functio nality or a collection of several
smaller functionalities of the SmartSwitch 6000 and Matrix E7 modules and the chassis in
which they are installed. This guide contains information about software functions which
are accessed directly from the device icon; additional management information about
tools and features common to many devices can also be found in the Element Manager

User’s Guide, the Element Manager Tools Gu ide, the Remote Administration Tools
User’s Guide, the Alarm and Event Handling User’s Guide, and the RMON User’s
Guide.

Because the aforementioned modules share much of their functionality, they will be
collectively referred to as the SmartSwitch 6000 and Matrix E7 modules. Where there are
differences, however , each device will be named separately , as necessary. The information
displayed in many of the wi ndows will differ slightly depending upon which type of
device is being managed; however, only a single window will be shown unless significant
differences in functionality exist.

Introduction

Chapter 1, Introduction, provides a list of related documentation and shows you how to
contact the Enterasys Global Call Center. It also briefly describes the SmartSwitch 6000
and Matrix E7 modules and 6C105/6C107 chassis.

Chapter 2, The Device View, describes the visual display of the SmartSwitch 6000 and
Matrix E7 chassis as a whole and explains how to use the mouse within the Device View.
It also details all chassis-level management functions, including Find Source Address,
Port Redirect, Advanced Priority Configuration, and pre-standard 802.1Q port-based
VLAN configuration at the chassis level. It also documents chassis-specific information,
including MIB-II System Group information, chassis IP and MAC addresses, chassis
clock information and uptime, power supply configuration and status, fan operational
status, and backplane configuration.

The chapter also details how each module is displayed in the chassis, and explains how to
access management menus from the module display and ch ange port status information. It

also explains how to manage the individual module by monitoring the module’s system
resources, finding a source address on the module, establishing module-level port
priorities, setting up broadcast supp res sion on the device, and configuring the module’s
front panel COM port and any attached Uninterruptable Power Supply (UPS).

Chapter 3, Statistics, describes the two statistics views available at the interface level:
MIB-II Interface statistics and RMON Ethernet statistics.

Chapter 4, Alarm Configuration , provides instructions for using both the Basic and

Mode, or configure operational parameters for Fast Ethernet ports, depending on the
type of interface selected.

• Alarm Configuration launches the RMON-based Basic and Advanced Alarm
applications; see Chapter 4, Alarm Configuration, for details. Note that this selection
is available for all bridge port interfaces — even those (like ATM) that do not
specifically support RMON functionality — as lo ng as at least one Ethernet or Fast
Ethernet port is on the module.

•Statistics launches the highest level of statistics currently available for the selected
port. For standard Ethernet and Fast Ethernet ports, RMON statistics will be displayed
if the RMON Default MIB component is active; if it has been disabled, MIB-II
interface statistics will display. See Chapter 3, Statistics, for more information.

Enabling and Disabling Ports, on page 2-104, for more information.

Port Stat us Displays

When you open the Logical View of the chassis, each port will display its current bridging
state (defined below), with the exception of SmartSwitch 6000 or Matrix E7 Ethernet
MicroLAN ports, which will display their Admin/Link status (also defined below) by
default; to change this status display, select one of the options on the Port Status menu, as
described in the following sections.

Selecting a Port Status View

To change the status view of your ports:

1. Click on Port Status on the menu bar at the top of the Device View window; a
menu will appear.

2. Select the status information you want to display. The port text boxes will
display the appropriate status information.

Port status view options are:

2-14 Viewing Device Information

The Device View

Status

You can view four port status categories, as follows:

• Bridge — FWD, DIS, LRN, LIS, BLK, or BRK

• Bridge Mapping — the instance of the physical interface associated with a bridge port

• Admin — ON or OFF

• Operator — ON or OFF

If you have selected the Bridge status mode, a port is considered:

• FWD (Forwarding) if the port is on-line and ready to forward packets across the

SmartSwitch 6000 or Matrix E7 from one network segment to another. This is also the
default display for ports which are administratively enabled but not connected. In
pre-5.1.x firmware, the default state of a por t not in use is “forwarding,” whereas in the

5.1.x firmware, the default is “blocking” (BLK).

• DIS (Disabled) if bridging at the port has been disabled by management; no traf fic can

be received or forwarded on this port, including configuration information for the
bridged topology.

• LIS (Listening) if the port is not adding information to the filtering database. It is

monitoring Bridge Protocol Data Unit (BPDU) traffic while preparing to move to the
forwarding state.

• LRN (Learning) if the Forwarding database is being created, or the Spanning Tree

Algorithm is being executed because of a network topology change. The port is
monitoring network traffic, and learning network addresses.

• BLK (Blocking) if the port is on-line, but filtering traffic from going across the

SmartSwitch 6000 or Matrix E7 from one network segment to another. Bridge
topology information will be forwarded by t he port. In the 5.1.x firmware , t he default
state of a port not in use is “blocking,” whereas in previous firmware versions, the
default is “forwarding” (FWD).

• BRK (Broken) if the physical interface has malfunctioned.
If you have selected the Bridge Mapping status mode, the port display will alter to show

the dot1dBasePortIfIndex, which is the value of the instance of the interface index (the
MIB II ifIndex) that corresponds to each bridge/switch port on the device. For a
SmartSwitch 6000 or Matrix E7 module, the dot1dBasePortIfIndex of the bridge
interfaces will map directly to the ifIndex.

If you have selected the Admin status mode, a port is considered:

• ON if the port is enabled by management.

• OFF if it has not been enabled or if it has been disabled through management action.
The Admin state reflects the state requested by management; depending on the

circumstances, this may or may not match the current Operator status, described below.

Viewing Device Information 2-15

The Device View

If you have selected the Operator status mode, a port is considered:

• ON if the port is currently forwarding packets.

• OFF if the port is not currently forwarding packets.

Note that the Operator status provides the actual status of the port; depending on the
circumstances, this may or may not reflect the Admin state currently requested by
management. For example, ports which are administratively ON but not yet connected
would display an Operator status of OFF, since no packets are being forwarded.

Load

If you choose Load, the interface text boxes will display the percentage of network load
processed by each port during the last polling interval. This percentage reflects the
network load generated per polling interval by devices connected to the port compared to
the theoretical maximum load (10, 100, 155.5, 800, or 1000 Mbps) of the connected
network.

Errors

If you choose the Errors mode, the interface boxes will display the percentage of the total
number of valid packets processed by each port during the last polling interval that were
error packets. This percentage reflects the number of errors generated during the last
polling interval by devices connected to that port compared to the total number of valid
packets processed by the port.

NOTE

The polling interval is set using the Device Management page of the Options window,
accessed via the To ols—>O ptions selection fr om the main menu bar. Refer to the Element
Manager User’s Guide for full information on setting node pol ling intervals.

I/F Mapping

If you choose the I/F Mapping mode, the interface boxes will display the interface number
(ifIndex) associated with each port on the SmartSwitch 6000 or Matrix E7 module.

I/F Speed

If you choose the I/F Speed mode, the interface boxes will display the bandwidth of each
individual port on the SmartSwitch 6000 or Matrix E7 module: 10M (megabits) for
standard Ethernet; 100M for Fast Ethernet, 155.5 M for ATM, 800M for a backplane
interface, and 1.00 G for Gigabit Ethernet.

I/F Type

If you choose the I/F Type mode, the interface boxes will display the network type
supported by each interface on the SmartSwitch 6000 or Matrix E7 module, e.g., Eth
(ethernet-csmacd), ATM, or FDDI. Note that there is no type distinction between standard
Ethernet, Fast Ethernet, and Gigabit Ethernet.

Port status view options for a SmartSwitch 6000 or Matrix E7 Ethernet MicroLAN
module are:

Load

If you choose Load, the port text boxes will display the percentage of network load
processed by each port during the last polling interval. This percentage reflects the
network load generated by devices connected to the port compared to the theoretical
maximum load (10, 100, 155.5, 800, or 1000 Mbps).

Port Assignment

If you choose Port Assignment, each port’s status box will display a letter which
designates its current repeater channel assignment (A-H).

Status

You can view three status categories for your p orts which reflect six possible Adm in/Link,
Admin, or Link Status conditions:

• Admin/Link — ON, OFF, SEG (segmented), or NLK (not linked)

• Admin — ON or OFF

• Link — LNK (link), NLK (not linked), or N/A (not available)
If you have selected the Admin/Link status mode, a port is considered:

• ON if the port is enabled and has a valid link.

• OFF if it has not been enabled or if it has been disabled through management action.

• SEG (segmented) if the port has been enabled by management and has a valid

connection, but has been segmented by the repeater because 33 consecutive collisions
have occurred on the attached segment, or the collision detector was on for more than

2.4 µs.

• NLK (Not Linked) when the port is on, but there is no physical link to the port. This

field is a combination of two status conditions: No Link and Port Administrative Status
On.

If you have selected the Admin status mode, a port is considered:

• ON if the port is enabled.

• OFF if the port has been disabled by management.
These conditions do not reflect link status.

Viewing Device Information 2-17

The Device View

NOTE

If you have selected the Link status mode, a port is considered:

• LNK (Linked) when a valid link has bee n esta blished bet ween t he port and the devi ce
at the other end of the segment.

• NLK (Not Linked) when the port is on, but there is no physical link to the port or the
device at the other end of the port’s segment is down.

• N/A (not available) when NetSight Element Manager cannot determine the link status
for the port.

Because BNC thin coax and AUI ports do not support the link feature, the displayed
Admin/Link, Admin, and Link status co nditions will not always follow the pattern
described above:

Under Admin/Link statu s mo de, BNC ports will display as ON if there is a valid
connection and the por t has b een enabled; OFF if the port has been di sa bled; and SEG if
the port has experienced 33 consecutive collisions or if there is no cable attached. An AUI
port will display as ON i f th e por t has been enabled (regardless of whether or not there is
a valid connection), OFF if the port has been disabled, and SEG if the port has detected
33 consecutive collisions. Note that the Admin/Link status displays for BNC and AUI
ports can be misleading in terms of troubleshooting; be sure to keep in mind that a BNC
port displaying as segmented may only have had its cable disconnected, and an AUI port
that appears to be on and linked may not have any cable attached.

Under Admin status mode, AUI and BNC ports will display as ON if the port has been
enabled, and OFF if it has been disabled; as with other port types, these ON and OFF
conditions indicate nothing about link status.

Under Link status mode, AUI and BNC port display boxes w ill display N/A, indicating
that NetSight Element Manager is u nable to determine their link status.

Errors or Frame Size

If you choose the Errors or Frame Size modes, additional menus offer the following
options for each mode:

Errors Total Errors, Collisions, Alignment, CRC, R unts, Giants, or OOW

Collisions

Frame Size Runts, 64-127, 128-255, 256-511, 512-1023, 1024-1518, or Giants

2-18 Viewing Device Information

The port status boxes will display the percentage for each active port that represents what

portion of that port’s total traffic is of the specific type (Errors or Frame Sizes) that you
selected. Select one of the Errors options to see what percentage of the total packets
received by each active port during the last polling interval was of the error type you
selected. This percentage reflects the number of errors generated by devices connected to
that port in relation to the total number of packets processed by the port (errors [errors +
packets]). Choose the Frame Size option to check on the sizes, in bytes, of frames passing
through your ports. The percentages are calculated just like the Errors selection described
above: the number given represents the number of packets of the selected size generated
by devices connected to that port in relation to the total number of packets processed.
Remember, these percentages are calculated based on the numbers of packets processed
during one polling cycle.

Port Status Color Codes

Three of the Port Status display options — Bridge, Admin, and Operator — incorporate
their own color coding schemes: for the Bridge option, green = FWD, blue = DIS,
magenta = LIS or LRN, orange = BLK, and red = BRK; for Admin and Operator, green =
ON, red = OFF, and blue = N/A (not available).

The Device View

For all other Port Status selections — Bridge Mapping, Load, Errors,
I/F Mapping, I/F Speed, and I/F Type — color codes will continue to reflect the most
recently selected mode which incorporates its own color coding scheme.

For a SmartSwitch 6000 or Matrix E7 Ethernet MicroLAN module, three of the port status
display options — Port Assignment, Port Type, and Status — incorporate their own color
coding schemes. For any of th e Status display options — Admin/Li nk, Adm in, o r Link —
green = ON/LNK, yellow = SEG/NLK, red = OFF, and blue = N/A (not available). For the
Port Assignment display option, Channel A = magenta, Channel B = olive, Channel C =
cyan, Channel D = yellow, Channel E = orange, Channel F = white, Channel G = green,
Channel H = hot pink. For the Port Type display option, station p orts will display as
yellow; trunk ports will display as green.

For all other MicroLAN Port Status selections — Load, Errors, and Frame Size — color
codes will continue to reflect the most recently selected mode which incorporates its own
color coding scheme.

The Chassis Manager Window

Like most networking devices, Cabletron and Enterasys devices draw their functionality
from a collection of proprietary MIBs and IETF RFCs. In addition, certain Enterasys

intelligent devices — like the SmartSwitch 6000 or Matrix E7 module — organize their
MIB data into a series of “components.” A MIB component is a logical grouping of MIB
data, and each group controls a defined set of objects. For example, SmartSwitch 6000 or
Matrix E7 module bridging information is organized into its own co mponent; Local
Management (LIM) and RMON are also contained in separate components. Note, too, that
there is no one-to-one correspondence be tween MIBs and MIB compon ents; a single MIB
component might contain objects from several different proprietary MIBs and RFCs.

The Chassis Manager window, Figure 2-5, is a read-only window that displays the MIBs
and the MIB component s — and, t herefore, t he function ality — s upported by the curren tly

Raw Counts

The total count of network traffic received or transmitted on the indicated interface since
device counters were last reset. Raw counts are provided for the following parameters:

In Octets Octets received on the interface, including framing characters.
In Packets Packets (both unicast and non-unicast) received by the device

interface and delivered to a higher-layer protocol.

In Discards Packets received by the device interface that were discarded

even though no errors prevented them from being delivered to
a higher layer protocol (e.g., to free up buffer space in the
device).

In Errors Packets received by the device interface that contained errors

that prevented them from being delivered to a higher-layer
protocol.

In Unknown Packets received by the device interface that were discarded

because of an unknown or unsupported protocol.

Out Octets Octets transmitted by the interface, including framing

characters.

Out Packets Packets transmitted, at the request of a higher level protocol,

by the device interface to a subnetwork address (both unicast
and non-unicast).

Out Discards Outbound packets that were discarded by the device interface

even though no errors were detected that would prevent them
from being transmitted. A possible reason for discard would be
to free up buffer space in the device.

Out Errors Outbound packets that could not be transmitted by the device

interface because they contained errors.

Load

The number of bytes processed by the indicated interface during the last poll interval in
comparison to the theoretical maximum load for that interface type (10 Mbps for standard
Ethernet; 100 Mbps for Fast Ethernet or FDDI; 155.5 Mbps for ATM; 800 Mbps for a
backplane port; 1000 Mbps for Gigabit Ether net). Load is further defin ed by the following

Three informational fields appear in the upper portion of the window:

Description

Displays the interface description for the currently selected interface (e.g., Enterasys Enet

Address

Displays the MAC (physical) address of the selected interface.

Type

The lower portion of the window provides the following transmit and receive statistics;
note that the first four statistics are also graphically displayed in the pie charts.

Unicast

Displays the number of packets transmitted to or received from this interface that had a
single, unique destination address. These statistics are displayed in the pie chart,
color-coded green.

Non-Unicast

Displays the number of packets transmitted to or received from this interface that had a
destination address that is recognized by more than one device on the network segment.

The multicast field includes a count of broadcast packets — those that are recognized by
all devices on a segment. These statistics are displayed in the pie chart, color-coded dark
blue.

Discarded

Displays the number of packets which were discarded even though they contained no
errors that would prevent transmission. Good packets are typically discarded to free up
buffer space when the network becomes very busy; if this is occurring routinely, it usually
means that network traffic is overwhelming the device. To solve this problem, you may
need to re-configure your bridging parameters, or perhaps re-configure your network to
add additional bridges or switch e s. Consult the Enterasys Network Troubleshooting
Guide for more information.

These statistics are displayed in the pie chart, color-coded magenta.

Error

Displays the number of packets received or transmitted that contained errors. These
statistics are displayed in the pie chart, color-coded red.

Unknown Protocol

Displays the number of packets received which were discarded because they were created
under an unknown or unsupported protocol.

Packets Received

Displays the number of packets received by the selected interface.

Transmit Queue Size

Displays the number of packets currently queued for transmission from this interface. The
amount of device memory devoted to buffer space, and the traffic level on the target
network, determine how large the output packet queue can grow before the SmartSwitch
6000 or Matrix E7 module will begin to discard packets.

Packets Transmitted

Displays the number of packets transmitted by this interface.

Making Sense of Detail Statistics

The statistics available in this window can give you an idea of how an interface is

Managing the Module

In addition to the performance and configuration information described in the preceding
sections, the Device View also provides you with the tools you need to configure your
SmartSwitch 6000 or Matrix E7 module and keep it operating properly. Hub management
functions include setting operatin g parameters for Ethernet, FDDI, Fast Ethernet, Gigabit
Ethernet and COM ports; managing an attached UPS; redirecting traffic from one module
interface to another; setting port priority parameters; configuring transmission thresholds
for broadcast packets; viewing and configuring system resources; setting device date and
time; and enabling and disabling bridging at specific port interfaces.

Configuring Ports

The Configuration options available for FDDI, Ethernet, Fast Ethernet, Gigabit Ethernet
and COM ports allow you to configure operating parameters specific to each port type: for
FDDI and standard Ethernet ports, you can set the Duplex Mode; for Fast Ethernet ports
on first generation modules, you can set a variety of duplex mode and negotiation
parameters; for Fast Ethernet and Gigabit Ethernet ports on second generation modules
you can set speed, duplex mode , and flow contro l parameters ; and for COM por ts, you can
select the operation you wish the port to perf orm, and set any associated speed p arameters.
FDDI, Ethernet, Fast Ethernet and Gigabit Ethernet Port Configuration windows are

2-36 Managing the Module

available from the Device View Port menus (except on Ethernet MicroLAN modules
where they are available from the Bridge Port menu); the COM Port option is available
from the Device menu. Note that no configuration option currently exists for ATM ports.

Configuring Standard Ethernet and FDDI Ports

The Port Configuration window available for both standard Ethernet and FDDI ports
allows you to set an interface to either Standard or Full Duplex Mode. Full Duplex mode
effectively doubles the available wire speed by allowing the interface to both receive and
transmit simultaneously. This window will also display the mode currently in effect on the
selected interface.

TIP

WARNING

If you select the Configuration option availab le for a Fast Ethernet interface, an entirely
different window will appear; see Configuring Fast Ethernet Ports on First Generation

Modules, on page 2-39, or Configuring Ethernet Ports on Second Generation Modules,

page 2-44, for information on configuring these ports.

For standard Ethernet interfaces, Full Duplex should only be enabled on an interface that
has a connection to a single destination address at the other end of the connection (i.e., it
is not a segment with an attached repeater cascadin g the connection to multiple
destination addresses).

Full Duplex mode disables the collision detection circuitry at the interface, so that bo th
Transmit and Receive wir es can be used simultaneously. W ith a single destination addr ess
at the other end of the connection (for example, if the connection was to a full duplex
interface on another switching module, or if a single file server was connected to the full
duplex switch port), this essentially doubles the available bandwidth from 10 Mbit/sec to
20 Mbit/sec. Note that the interface at the other end of the connection must also have Full
Duplex enabled at the attached interface.

Full Duplex mode must be disabled if the interface is communicating with multiple
destinations simultaneously (i.e., if a repeater is cascaded from the interface), since
Ethernet relies on Collision Sense for proper operation.

Similarly, an FDDI Full Duplex connection must also only be run point-to-point between
two supporting FDDI interfaces (e.g., another HSIM-F6), since the dual bandwidth is
attained by running data on both pr imary and s econdar y paths simul tane ously. Since Full
Duplex overrides standard FDDI protocol (and eliminates ring redundancy), it will not

operate in a “ring” configuration, but only as a point-to-point high speed data trunk
between hubs. Note that you must use Local Management to configure your HSIM-F6 for
Full Duplex operation prior to making physical connections. Refer to your Local
Management Guide for more information.

Use the options in this window to select the desired mode:

Standard Mode

In Standard Mode, an interface can only either transmit or receive at any given time, and
must wait for one activity to be completed before switching to the next activity (receive or
transmit). In this mode, st andar d wire s peed s (10 Mbp s f or Ethern et, 10 0 Mbp s for F DDI)
are available.

Full Duplex

In Full Duplex Mode, an interface can bo th r eceive and transmit packets at the same time,
effectively doubling the available wire speed to 20 Mbps (for Ethernet) or 200 Mbps (for
FDDI).

Be sure to click on the Apply button to set your changes; note that the interface’s current

mode can be determined by the field selected in the window.

Configuring Fast Ethernet Ports on First Generation Modules

The Fast Ethernet Configuration window available for Fast Ethernet ports on first
generation modules (e.g., 6H1 22-xx an d 6H128-0 8) allows you to both view and set t hose

ports’ available modes. All 100Base-TX Fast Ethernet ports can be configured to operate
in either standard Ethernet (10 Mbps) or Fast Ethernet (100 Mbps) mode, and in each
mode can be configured to operate in Full Duplex, effectively dou bling the available wire
speed (from 10 to 20 Mbps in standard Ethernet mode, or from 100 to 200 Mbps in Fast
Ethernet mode); 100Base-FX (fiber) ports can be configured to operate in their standard
100 Mbps mode, or in Full Dupl ex mode. Th is window al so display s the mod e currently in

Link State

Displays the current connection status of the selected port: Link or No Link.

Current Operational Mode

Indicates which of the available operational modes is currently in effect: 10Base-T,
10Base-T Full Duplex, 100Base-TX, 100Base-TX Full Duplex, 100Base-FX, or
100Base-FX Full Duplex. If the port is still initializin g, not linked, or if there is no port
module installed in the slot, this field will remain blank.

Desired Operational Mode

Displays the operational mode that you have selected for th is port, and allows you to
change that selection. The following operational modes are available for each port:

!

CAUTION

100Base-TX Auto-Negotiation, 10Base-T, 10BASE-T Full Duplex, 100Base-TX,

and 100Base-TX Full Duplex.

100Base-FX 100Base-FX and 100Base-FX Full Duplex

If you choose to select a specific mode of operation (rath e r than auto-negotiation), you
should be sure that the link partner supports the same mode. Otherwise, no link will be
achieved.

If you select a Full Duplex mode and the link partner supports the same wire speed but not
Full Duplex, a link will be achieved, but it will be unstable and will behave erra tically.

If you select Auto-Negotiation, the local node will try to match the mode of the link
partner, even if the link partner is not set to auto-negotiate, and even if the local node must
use a mode which it is not currently advertising.

Note that if Auto-Negotiation is the selected mode, the Current Operational Mode field
will indicate which mode was selected by the link partne r.

See Setting the Desired Operational Mode, on page 2-42, for more information.

Advertised Abilities

For 100Base-TX ports which have been configured to operate in Auto-Negotiation mode,
this field allows you to select which of the operational modes available to the port can be
selected by the negotiating link partners.

Managing the Module 2-41

The Device View

NOTE

During Auto-Negotiation, each of the link partners will advertise all selected modes in
descending bandwidth order: 100Base-TX Full Duplex, 100Base-TX, 10Base-T Full
Duplex, and 10Base-T. Of the selected abilities, the highest mode mutually available will
automatically be used. If there is no mode mutually advertised, no link will be achieved.

If you have selected a specific operational mode for your 100Base-TX port, the
Advertised Abilities do not apply; the selected Advertised Abilities also do not restrict the

local node’s ability to set up a link with a partner who is not currently Aut o-Negotiating.

Auto-Negotiation is not currently supported for 100Base-FX ports.

Remote Capabilities

When the local node is set to Auto-Negotiation, this field will display the advertised
abilities of the remote link — even if the remote link is not currently set to auto-negotiate.
Possible values for this field are:

NOTE

• 100Base-TX Full Duplex

• 100Base-TX

• 10Base-T Full Duplex

• 10Base-T

• Link Partner does not support Auto-Negotiation — Auto-Negotiation is either not
supported by or is not currently selected on the remote port.

• Unknown — the link partner ’s capabilities could not b e determ ined.

When the local node is not set to Auto-Negotiation, this field will be grayed out, even if
the link partner is set to Auto-Negotiation and is advertis ing abilities.

If both link partners are set to Auto-Negotiation, but there is no mutually-advertised
operational mode, no link will be achieved, and both nodes may display the message

“Link Partner does not support Auto-Negotiation.” T o resolve this situation, be sure both
link partners advertise all their abilities, or be sure they advertise at least one
mutually-available mode.

Setting the Desired Operational Mode

For any 100Base-TX port, you can specifically choose any one of the four available
operational modes, or you can select Auto-Negotiation mode, which allows the port to
negotiate with its link partner to find the highest m utually available bandwidth. If you
select Auto-Negotiation mode, you must also choose which of the port’s bandwidth
capabilities you wish to advertise to the link partner.

2-42 Managing the Module

TIP

The Device View

If you select Auto-Negotiation at both ends of a link, be sure at least one
mutually-advertised operational mode is available.

For a 100Base-FX port, the selection process is somewhat simpler; Auto-Negotiation for
these ports is not supported at this time, so you need only choose between 100Base-FX
standard mode and 100Base-FX Full Duplex. However, you must still be sure that both
link partners are set to the same operational mode, or the link will be unstable.

To set your desired operational mode:

1. Click on the Desired Operational Mode list box to display the menu of

available options; click to select the operational mode you wish to set.

For 100Base-TX ports, the available options are:

Auto Negotiation — the operational mode will be dynamically set based on
the modes selected in the Advertised Abilities field (where both link partners
are auto-negotiating) and the speeds and modes supported by the attached
device

TIP

10Base-T — 10 Mbps connection, Standard Mode
10Base-T Full Duplex — 10 Mbps connection, Duplex Mode
100Base-TX — 100 Mbps connection, Standard Mode
100Base-TX Full Duplex — 100 Mbps connection, Duplex Mode

For 100Base-FX ports, options are:

100Base-FX — 100 Mbps connection, Standard Mode
100Base-FX Full Duplex — 100 Mbps connection, Duplex Mode

2. If you have selected Auto-Negotiation (for 100Base-TX ports only), use the

Advertised Abilities field to select the operational capabilities you wish to
advertise to the port’s link partner. If both link partners will be auto-negotiating,
be sure there is at least one mutually-advertised operational mode, or no link
will be achieved.

The selected Advertised Abilities only come into play when both link partners are
auto-negotiating; if only one link partner is set to auto-negotiate, that node will establish
a link at whatever mode its partner is set to, even if that mode is not currently being
advertised.

Configuring Ethernet Ports on Second Generation Modules

The Ethernet Configuration wi ndow availab le for Fast Ethernet and Gig abit Ethernet ports
on second generation modules (e.g., 6E233-49 and 6H258-17) allows you to both view

and set those ports’ available speed, modes, and flow control. All second generation
modules support t he ctEthernetParameters MIB. All Ethernet ports that return at least one
instance for a query of the ctEtherSupportedDuplex OID will use the Ethernet
Configuration window as shown in Figure 2-16.

All 100Base-TX Fast Ethernet ports can be configured to operate in either standard
Ethernet (10 Mbps) or Fast Ethernet (100 Mbps) mode, and each mode can be configured
to operate in Full Duplex effectively doubling the available wire speed (from 10 to 20
Mbps in standard Ethernet mode, or from 100 to 200 Mbps in Fast Ethernet mode).
100Base-FX (fiber) ports can be configured to operate in their standard 100 Mbps mode,
or in Full Duplex mode. 1000Base-SX/LX/CX Gigabit Ethernet ports are always
configured to operate in 1000 Mbps, Full Duplex mode.

This window displays the mode currently in effect on the selected interface, and provides
some information (where it is available) about the interface’s link partner.

values for this field are: configuring, complete, disabled, parallel detect failed, or other.

Auto Negotiate Mode

Use this field to enable or disable Auto Negotiate for the port. If Auto Negotiate is
disabled, the port will use the speed, duplex mode, and flow control settings specified in
the Operational Mode fields. Note that 100-BaseFX ports do not support Auto
Negotiation; they must use the control settings specified in the Operational Mode fields.

!

CAUTION

Operational Mode Fields

If the port is not set to Auto Negotiate then the settings in the Operational Mode fields are
used.

If you choose to select a specific mode of operation (rath e r than auto negotiation), you
should be sure that the link partner supports the same mode. Otherwise, no link will be
achieved.

For example, if you select Full Duplex mode and the link partner supports the same wire
speed but not Full Duplex, a link will be achieved, but it will be unstable and will behave
erratically.

If you select Auto-Negotiation, the local node will try to match the mode of the link
partner, even if the link partner is not set to auto-negotiate, a nd even if the local node must
use a mode which it is not currently advertising.

The Current Operational Mode settings indicate which of the available operational
modes is currently in effect. If Auto Negotiate is the selected mode, the Current
Operational Mode fields will indicate which mode was selected by the link partner.

The Desired Operational Mode settings display the operational mode that is currently
selected for this port, and allows you to change the selection.

The following operational modes can be specified:

Speed

This field specifies a port speed of 10MB, 100MB, or 1000MB.

2-46 Managing the Module

The Device View

Duplex

This field specifies Half Duplex or Full Duplex mode for the port.

Flow Control

Flow control allows Ethernet devices to notify attached devices that congestion is
occurring and that the sending device should stop transmitting until the congestion can be
cleared. There are two commonly used methods of flow control: Frame-based (operates on
Full Duplex links) and Backpressure (operates on Half Duplex links).

Ports set to Full Duplex mode have frame-based flow control, using pause control
frames. Frame-based flow control options are:

Symmetric The port is able to both receive and transmit pause control frames.
Asymmetric RX This option appears only for Gigabit Ethernet ports. The port will

receive pause control frames, but will not transmit its own.

Asymmetric TX This option appears only for Gigabit Ethernet ports. The port is

capable of sending pause control frames, but will not acknowledge
received pause control frames.

Disabled Disables flow c ontrol on the port.
Auto Negotiate Ports co nfigured to operate in auto negotiation mode will only use

pause control frames if the negotiation process determines that the link
partner supports them. Both ends of the link must support auto
negotiation and a common mode of operation.

Ports set to Half Duplex mode use Backpressure flow control. Backpressure flow control
simply asserts the carrier sense signal out the port causing the device transmitting to detect
a collision, stop transmitting data, and sen d the jam signal. Backpressure flow control
options are enabled or disabled.

Setting the Desired Operational Mode

For any 100Base-TX port, you can configure operational modes, or you can select Auto
Negotiate mode, which allows the port to negotiate with its link partner to find the highest
mutually available bandwidth and flow control. If you select Auto Negotiate mode, you

must also choose which of the port’s bandwidth and flow control capabilities you wish to
advertise to the link partner (refer to Auto Negotiation Technologies, page 2-48).

100Base-FX ports do not support auto negotiation for bandwidth or flow control
capability, so you must choose between 100Base-FX Half Duplex and 100Base-FX Full
Duplex mode, and set the flow control option. H owever, you must still be sure that both
link partners are set to the same operational mode, or the link will be unstable.

For 1000Base-SX/LX/CX ports the speed and duplex modes are always configured at
1000MB Full Duplex. However, you can select Auto Negotiate mode, which allows the
port to negotiate with its link partner to find the highest mutually available bandwidth and
flow control. If you select Auto Negoti ate mod e, you must also choose which of the port ’s
bandwidth and flow control capabilities you wish to advertise to the link partner (refer to

Auto Negotiation Technologies, page 2-48).

Redirecting Traffic

The Port Redirect window (Figure 2-19) allows you to redirect traffic from one or more

interfaces directly to another interface — essentially mirroring the traffic at the “redirect”
interface. This feature is useful in that it allows you to use an external analyzer on the
“redirect” port to analyze data, without disturbing the normal switching operations at the
original source ports. The Port Redirect window displays the interface remap table and
allows you to add new entries to and delete existing entries from this table. When you set
a source port to redirect to a destination port, the destination po rt wi ll transmit out all
packets received or transmitted on the source port.

To access the Port Redirect window:

1. In the Chassis View window, select Device>Port Redirect (if you are

Priority Configuration

The SmartSwitch 6000 and Matrix E7 modules support priority packet forwarding.
Priority packet forwarding lets you designate certain packets to be of higher importance
than others, thereby allowing for the forwarding of these packets before packets of lower

priority. This functionality is essential for time-critical applications — such as real-time
video — on shared networks.

The Priority Configuration menu option will only appear in the Device menu for modules

NOTE

that respond to any of NetSight Element Manager’s queries to the following OIDs:
ctPriorityExtPortStatus, ctPriorityExtMaxNumMACEntries, or
ctPriorityExtNumPktTypeEntries. If your module’s firmware does not respond to these

queries, contact the Enterasys Global Call Center for firmware upgrade information.

Frame priority is enabled by the “tagging” of MAC frames so that they are given a priority
designation when they are forwarded by the SmartSwitch 6000 or Matrix E7 module —
which is a tag-aware switch (i.e., one that adheres to the IEEE P802.1p and IEEE P802.1q
Draft Standards). Tagging a frame is accomplished by adding a Tag Header to a frame
immediately following its original Destination and Source MAC address fields (and any

2-56 Managing the Module

The Device View

routing fields, if present), and then recomputing the Frame Check Sequence (FCS)
appropriately. On receiving such a frame, a tag-aware switch will read the priority from
the tagged portion of the frame, remove the Tag Header, recompute the FCS, and then
direct it to its appropriate transmission queue.

There are eight priority levels — indicated 0 through 7— available to designate user
priority . Frames tagged with a 0 represen t the lowest priority level (o r no rmal) traffic, and
frames tagged with a 7 indicate the highest priority level traffic.

The 6000 and Matrix E7 series modules themselves support two transmission queues: one
that is for 0 or normal priority traffic (or any non-tagged traffic), and a second queue that
is reserved for frames that have been tagged with a priority level of 1 or higher. On
receiving any priority-tagged frames, the SmartSwitch 6000 or Matrix E7 will forward
them out of the high priority queue before forwarding any frames in the normal priority
queue. However, the SmartSwitch 6000 or Matrix E7 will tag outgoing frames with the
full range of eight priority levels, so that upon reception, a device that supports the entire
range of priority queuing will forward the frame appropriately.

You can use NetSight Element Manager to configure the criteria that determine the
priority in which frames will be queued for transmissio n by your SmartSwitch 6000 or
Matrix E7 module. Several different criteria can be used to determine a frame’s
transmission queue order:

• The module and port at which the frame was received.

• The destination and/or source MAC address associated with the frame.

• A combination of destination and/or source MAC address and the frame’s protocol

type.

• The frame’s protocol type.
When you configure the transmission queue for a specific frame, an entry is made in one

of three priority tables maintained by the SmartSwitch 6000 or Matrix E7 module. These
tables are used to determine which transmit queue to use — normal priority or high
priority — when forwarding frames.

•The ctPriorityExtPortTable maintains priority entries based on a frame’s receive port.

•The ctPriorityExtMACTable maintains priority entries based on a frame’s MAC-layer

information.

•The ctPriorityExtPktTypeTable maint ai ns priority entries based on the frame’s

protocol type.

The following sections discuss how to use the Port Priority Configuration window, the
MAC Based Priority Configuration window, and the Frame Priority Configuration
window to make entries in these transmit priority tables.

Managing the Module 2-57

The Device View

Configuring Priority Queuing Based on Receive Port

You can use the Port Priority Configuration window, Figure 2-20, to determine packet
queuing based solely upon the port at which the packet was received. This allows you to
ensure that a connected user or LAN segment will have priority when frames that were
received on that port are queued for transmission.

Highlight a module/port, then
use the drop-down list box to

select a priority (Normal–7).

Click Apply to set the priority
at the device. Any priority of 1
or higher will allow packets
received at the chosen port to
be forwarded from the higher
priority transmission queue.

NOTES

Figure 2-20. The Port Priority Configuration Window

In the event that an incoming packet received on a designated port already has a priority
associated with it, you can use the ctPriorityExtPortFwdInboundPriority OID to
determine whether the incoming priority should remain intact, or be replaced with the
priority that you have set for the receiving port.

Use the MIB Tools utility suite to set the ctPriorityExtPortFwdInbound Prio rity OID to 1
(for the appropriate port instance) if you want the incoming packet to r etain its originally
set priority when received by the port; set the OID to 2 if you want the packet to take the
default priority set for the receiving port. Refer to the Element Manager Tools Guide for
information on usin g the MIB Tools suite.

To access the Port Priority Configuration window:

1. Click on Device to access the Device menu.

2. Drag down to Priority Configuration, and to the right to select Port Based
from the cascading menu. The Port Priority Configuration window
(Figure 2-20) will appear.

The Port Priority Configuration window displays the contents of the
ctPriorityExtPortTable. It has a list box that displays the front panel interfaces supported
by the SmartSwitch 6000 or Matrix E7 module, along with the slot number occupied by
the module, and any transmit priority that has been assigned to those interfaces.

2. Click on the Transmit Priority drop-down list box, and scroll to select the

desired priority level (Normal–7) for forwarding packets received on the
selected port.

Since the SmartSwitch 6000 a nd Matrix E7 modules have two transmit queues, a priori ty
of Normal will cause packets received on that port to be forwarded through the lower
priority queue, and any priority of 1 through 7 will cause the packets to be forwarded
through the higher priority queue. However, other tag-aware switches may use the full

range of eight pr i ority queu e s — s o the priority that you ass ig n ma y ha ve b e aring on how
the frame is forwarded when it is received by another device.

SmartSwitch 6000 or Matrix E7 for management are:

• None — the SmartSwitch 6000 or Matrix E7 will reserve all bandwidth for switching,

therefore management frames may be dropped under heavy loads.

• Limited — the management of the SmartSwitch 6000 or Matrix E7 may be slow while

the device is experiencing heavy switching loads.

• Full — management of the SmartSwitch 6000 or Matrix E7 is always possible and

management frames will take priority over switched data if full C PU ban dwidth is
required (switched frames may be dropped).

802.1Q VLANs

NOTES

What is a VLAN?

This section introduces and describes pre-standard IEEE 802 .1Q po rt-based Virtual Local
Area Network (VLAN) technology and the windows used to configure Enterasys 802.1Q
VLAN-capable devices.

SmartSwitch 6000 or Matrix E7 firmware version 4.00.08 and above support the
pre-standard IEEE 802.1Q draft specification for port-based VLANs.

In certain SmartSwitch 6000 firmware versions, 802.1Q operation is not fully
supported.Refer to your firmware release notes for more information.

A Virtual Local Area Network (VLAN) is a logical group of devices that function as a
single Local Area Network segment (broadcast domain). Devices comprising a VLAN
may be (physically) widely separated, allowing users located in separate areas or
connected to separate ports to belong to a single VLAN group. Users assigned to a VLAN
can send and receive broadcast and multicast traffic as though they were all physically
connected to a single network segment. VLAN-capable switches isolate broadcast and
multicast traffic received from VLAN groups, and contain broadcasts and multicasts from
members of a VLAN within that group.

What is an 802.1Q Port-Based VLAN?

Switches that support the pre-standard IEEE 802.1Q draft specification for port-based
VLANs act by classifying frames into VLAN membership. Usually, VLAN classification
is based on tag headers (VLAN tags) in the headers of data frames. The tag header is
inserted into the frame directly after the Source MAC address field. A four-byte field in
the tag header is used as the VLAN identifier. These VLAN tags are added to data frames
by the switch as the frames are transmitted and/or received by certain ports, and are later
used to make forwarding decisions by the switch and other 802.1Q switches. In the
absence of a VLAN tag, a frame is assigned VLAN membership according to the VLAN
configuration of the switch port that receives the frame.

About 802.1Q VLAN Configuration and Operation

An 802.1Q VLAN is defined by assigning it a unique identification number (the VLAN
ID) and an optional name. The VLAN ID is used to identify data frames that originate
from, and are intended for, the ports assigned to the VLAN. Up to 64 VLANs may be
created, with VLAN IDs ranging from 2-4094. VLAN ID 1 is reserved for the Default
VLAN.

2-70 Managing the Module

NOTE

NOTE

The Device View

Ports on 802.1Q switches are assigned membership in a VLAN by associating a VLAN ID

with each port on the switch. The VLAN ID is combined with the port’s identification
(e.g., module X port X) to form the Port VLAN ID (PVID).

When 802.1Q mode is initially activated on a device, all ports are associated with the
Default VLAN (VLAN ID 1). If a VLAN ID has not been assigned to a particular port on
an 802.1Q switch, any frames r eceived fr om that po rt will be classified as belonging to the
Default VLAN.

When 802.1Q is implemented for a SmartSwitch 6000 or Matrix E7 that has an
HSIM-A6DP installed, each LEC will be represented as an individual port which can be
easily assigned membership in a VLAN.

For SmartSwitch 6000 or Matrix E7 firmware versions 4.00.08 and above, the number of
LECs supported by the HSIM-A6DP in 802.1Q mode is limited to 32.

Once VLANs have been configured and activated, all frames with unknown destination
addresses (including broadcast, unknown multicast, and unknown unicast frames) will be
contained within the VLAN of their origin. The switch’s Filtering Database tracks the
associations between MAC addresses, VLAN eligibilities, and port numbers, and is used
to make forwarding decisions for frames. All VLANs share a single Spanning Tree.

Ingress List Operation

A port’s ingress list specifies the VLAN with which received frames will be associated.
The switch’s Filtering Database tracks the associations between VLAN eligibilities, MAC
addresses, and port numbers.

Untagged frames received by an 802.1Q switch port are classified accord ing to the VLAN
membership of the port that receives the frame.

Tagged frames received by an 802.1Q switch port are classified according to the VLAN
indicated in their tag header. A port may receive a tagged frame that specifies a VLAN
other than the one assigned to the port.

Egress List Operation

Each port’s egress list specifies which VLANs are associated with the port, and specifies
what type of frame (tagged and/or untagged) to transmit for each particular VLAN on a
port. This information may be statically defined by the user, or dynamically learned and
maintained by the switch’s Filtering Database.

Managing the Module 2-71

The Device View

If a port receives a tagged frame that specifies a VLAN other than the one assigned to the

port, the switch will dynamically associate that frame’s source address and VLAN with
the port (i.e., add that frame’s VLAN to the receiving port’s egress list). Dynamically
learned VLANs are subject to the same aging rules as source addresses (e.g., if a tagged
frame belonging to a dynamically learned VLAN is not received by the port within the
switch’s aging time, the transmitting station’s source address and VLAN will be aged out
for that port; no unknown destination frames belonging to the station’s VLAN will be
transmitted through the port until the VLAN is dynamically learn e d once again). Only
tagged frames can cause the switch to dynamically change a port’s egress list.

802.1Q Port Types

Each 802.1Q switch port is assigned a mode of operation. Port types include:

1Q Trunk

If VLAN membership is to apply to users across several switches, ports used to connect

802.1Q-aware devices are configured to use 1Q Trunk mode. In this mode, all frames

(except BPDUs) are transmitted with a tag header included in the frame, allowing VLAN
frames to maintain their VLAN ID across multiple switches. Any untagged frames
received by the port are dropped. 1Q Trunk ports are configured to be members of all
VLANs.

1d Trunk

This mode allows a port to transmit to a traditional (802.1d ) switch fabric. These ports
transmit only untagged frames, and the switch expects to receive only untagged traffic
through the port. 1d Trunk ports are configured to be members of all VLANs. This mode
can be used to share a connection among multiple VLANs (e.g., sharing a server between
two or more separate VLANs).

Hybrid

Hybrid mode (enabled by default) allows a port to receive and transmit b oth tagged and
untagged frames. In this mode, the port will be a member of its statically assigned VLAN,
as well as any dynamically learned VLANs (remember, dynamically learned VLANs are
subject to the same aging rules as source addresses).

Configuring Your 802.1Q VLANS

Before you can define an d configu re 802. 1Q port -based VLANs on your d evice, you must
activate the device’s 802.1Q operational mode; this operation can be performed using
Local Management or the MIB Tools application. Using MIB Tools, 802.1Q mode can be
activated through the Container MIB’s Logical Entry Table (contLogicalEntryTable).
When the 802.1Q component is activated, the device will automatically reset, and begin
operating in 802.1Q mode.

Refer to your device’s Local Management documentation for instructions on activating a
device’s 802.1Q operational mode via Local Management. For details on the MIB Tools
application, refer to your Element Manager Tools Guide.

2-72 Managing the Module

To set up your 802.1Q port-based VLANs using NetSight Element Manager, you must
first define the desired VLANs using the VLAN Config window (Figure 2-25), which
allows you to assign VLAN IDs and optional VLAN names, and enable or disable
VLANs.

After your VLANs are defined, you may configure the ingress and egress lists for each
port using the VLAN Port Config window (Figure 2-26) and the VLAN Egress Port
Config window (Figure 2-27), respectively.

Setting VLAN Parameters and Operational Modes

802.1Q VLANs are defined using the VLAN Config window, which is accessed from the

Device menu in your switch’s Device View. To launch the window:

1. Click on Device in the Device View menu bar to display the Device menu.

2. Drag down to 802.1Q VLAN, then right to select 802.1Q VLAN Config. The

VLAN ID

The VLAN ID is used to identify data frames that originate from, and are intended for, the
ports assigned to the VLAN. Up to 64 VLANs may be created, with VLAN IDs ranging

from 2-4094. The VLAN ID is combined with the port’s identification (e.g., module X
port X) to form the Port VLAN ID (PVID). VLAN ID 1 is reserved for the Default VLAN.

VLAN Name

An optional 32-character VLAN name may be assigned to a created VLAN. The Default
VLAN is assigned the name DEFAULT VLAN, which cannot be changed or deleted.

Admin Status

This field indicates whether the VLAN is enabled or disabled. Unless Enable is selected
when port-based VLANs are initially defined, they are disabled by default. The Default
VLAN cannot be disabled.

Creating and Modifying VLANs

The fields immediately below the Configured VLANS list box are used to create and
modify your port-based VLANs. To create a new VLAN:

NOTE

1. In the VLAN ID field, enter a unique value between 2-4094. VLAN ID 1 is
reserved for the Default VLAN, and cannot be used.

2. If desired, enter a name for the VLAN in the VLAN Name field. VLAN names
must be 32 characters or less.

Unless Enable is selected when a port-based VLAN is initially defined, it will be disabled
by default. A new VLAN that is left in a Disabled state will remain disabled until a port is
assigned to it, at which tim e it will b e automatically enabled. If you are changing a

VLAN’s port assignment, the VLAN should be disabled before changing the port
configuration. See Enabling and Disabling VLANs, on page 2-75, for instructions on
disabling VLANs. See Performing Ingress List Configuration, on page 2-75, for details
on completing your VLAN port con figuration.

3. Click the Apply button. The new VLAN will be added to the Configured
VLANS list box.

Once a VLAN has been created, its VLAN ID cannot be modified. If you wish to change a
VLAN’s ID, you’ll have to delete the VLAN and create a new entry. See Deleting

VLANs, below, for instructions on deleting a VLAN. Attempting to change a VLAN’s ID

will result in the creation of a new VLAN with the same VLAN name.
T o modify an existing VLAN’s name, select its entry in the Configured VLANS list box.

The selected VLAN’s name will be displayed in the VLAN Name field. Modify the
displayed name as outlined in Steps 2-3, above.
