Introduction to SPMA for the 7C0x SmartSwitch

How to use the 7C0x SmartSwitch User’s Guide; manual conventions; contacting Cabletron Technical
Support; 7C0x SmartSwitch firmware versions supported by SPMA

TIP

Your SPMA for the 7C0x SmartSwitch management module provides
management support for all three models in the 7C0x SmartSwitch family. The

7C03 MMAC SmartSwitch functions as a chassis within a chassis; residing in an

MMAC-series hub, it occupies two module slots and provides three slots of its
own — one for the 7X00 SmartSwitch Control Module, and two for its own family
of Network Interface Modules, or NIMs. The 7C04 Workgroup SmartSwitch is a
stand-alone chassis that offers four slots: one for the controller, and three for
NIMs. The 7C04-R Workgroup SmartSwitch supplies all the features of the 7C04
along with the additional fault tolerance provided by a pair of redundant
load-sharing power supplies and a removable fan tray. The 7C04-R can also
accept the new double-wide NIM modules (in slots 3 and 4) for additional front
panel connectivity.

The 7C03 MMAC SmartSwitch chassis provides no network connection to the MMAC
backplane (from which it draws only power). If you wish to connect one or more networks
from the MMAC chassis to the SmartSwitch chassis, you must do so via the front panel
ports available on both the MMAC MIMs and the SmartSwitch NIMs.

At the heart of each 7C0x SmartSwitch hub is its 7X00 SmartSwitch Control
Module, which supervises access to the switching backplane and performs all
forwarding, filtering, and connection management functions; a variety of NIM
modules provide connectivity for FDDI, Ethernet, Fast Ethernet, and ATM
networks. NIM modules currently available include:

1-1

Introduction to SPMA for the 7C0x SmartSwitch

• The 7E03-24 , a single-slot Ethernet module that provides 24 ports via two RJ71
connectors.

• The 7E02-24 , a double-wide Ethernet module for the 7C04-R which provides
24 ports via RJ45 connectors.

• The 7F06-02 , which provides connectivity for two FDDI ring networks via its
two front-panel FPIM slots; FPIM modules that support both multi-mode fiber
and single-mode fiber (both with MIC connectors) and both shielded and
unshielded twisted pair (with RJ45 connectors) are available.

• The 7H02-06 , which provides six Fast Ethernet connections — the first via a
Fast Ethernet Port Interface Module slot, and an additional five via built-in
Category 5 UTP RJ45 connectors. Two Fast Ethernet port modules are
available: the FE-100FX, which provides a single multi-mode fiber port with an
SC connector; and the FE-100TX, with a single Category 5 UTP RJ45 connector.

• The 7H02-12 , a double-wide module which provides 12 Fast Ethernet
connections — the first via a Fast Ethernet Port Interface Module slot, and
another 11 via built-in UTP RJ45s.

NOTE

• The 7H06-02 Fast Ethernet uplink module, which provides two Fast Ethernet
connections via Fast Ethernet Port Interface Module slots.

• The 7A06-01 , which provides a redundant ATM uplink connection via two
front panel ATM Port Interface Module slots. Available APIMs provide
connectivity for all standard ATM speeds and media types.

The available modules provide your SmartSwitch hub with key mission-critical
features such as redundant links, alarm thresholding, and full error breakdown;
Ethernet modules also provide per-port RMON support. By default, the 7X00
performs traditional switching (or bridging); depending on the version of
firmware you have installed, the 7X00 module can also be configured to perform
Cabletron’s SecureFast switching.

Not all released firmware versions support the ability to select SecureFast switching;
check your hardware manuals to see if your version of firmware supports this feature.
Currently, the toggle from traditional bridging to SecureFast switching is performed via
Local Management; see your Local Management documentation for details.

Note that because the 7C03, 7C04, and 7C04-R provide the same functionality and
support the same family of NIM modules (with the exception of the double-wide
modules, which can be installed only in a 7C04-R), they will be referred to
collectively throughout this manual as the 7C0x SmartSwitch. Where significant
differences exist, they will be noted.

Introduction to SPMA for the 7C0x SmartSwitch

Using the 7C0x SmartSwitch User’s Guide

Your SPECTRUM Portable Management Application (SPMA) for the 7C0x
SmartSwitch consists of a number of different applications, each of which
provides a portion of the overall management functionality. Each of these
applications can be accessed from the icon menu (if you are using a management
platform) and from the Stand-alone Launcher or the command line (if you are
running in stand-alone mode); in addition, several applications can also be
accessed from within the Hub View, a graphical display of the 7C0x SmartSwitch
hub and its installed modules.

The 7C0x SmartSwitch User’s Guide describes how to use many of the
applications included with the module; note that the instructions provided in this
guide apply to the 7C0x SmartSwitch module regardless of the operating system
or management platform you are using. Instructions for launching each
individual function from the command line (stand-alone mode) are also included
in each chapter.

Following is a description of the applications covered in this guide; while we
provide as much background information as we can, we do assume that you’re
familiar with Ethernet, Fast Ethernet, FDDI, and ATM networks, traditional
bridging and switching, and with general network management concepts:

• Chapter 1, Introduction to SPMA for the 7C0x SmartSwitch , describes the

7C0x SmartSwitch User’s Guide and the conventions used in this and other
SPMA manuals, explains where to find information about the 7C0x
SmartSwitch, and tells you how to contact Cabletron Systems Technical
Support.

• Chapter 2, Using the 7C0x SmartSwitch Hub View , describes the visual

display of the Hub and explains how to use the mouse within the Hub View;
some basic functions (changing the Hub View display, opening menus and
windows, enabling and disabling bridge ports, and so on) available only from
within the Hub View are also described. You can access the Hub View
application from the icon menu or the command line.

• Chapter 3, Alarm Configuration , describes how the 7C0x’s RMON

functionality allows you to set thresholds and enable or disable alarms for any
installed bridging interface based on selected MIB II statistics; this chapter also
describes how to specify a response to an alarm condition. You can access the
Alarm Configuration application from the icon menu, the Hub View, or the
command line.

• Chapter 4, FDDI Management , describes the five applications available for

managing any installed FDDI interfaces. You can access the FDDI applications
from the Hub View or the command line.

• Chapter 5, ATM Configuration , describes how to use the ATM configuration

application to view and configure the Permanent Virtual Circuits supported
by any installed 7A06-01 modules.

Using the 7C0x SmartSwitch User’s Guide 1-3

Introduction to SPMA for the 7C0x SmartSwitch

• Chapter 6, Using the 7C0x SmartSwitch Bridge View , provides detailed
instructions for configuring and managing the 7C0x SmartSwitch’s traditional
bridging capabilities, including monitoring bridge operation, using the special
and filtering data bases, and setting forwarding thresholds and notification
options. You can access the Bridge View from the icon menu, the Hub View, or
the command line.

• Appendix A, 7C0x SmartSwitch MIB Components , lists the IETF MIBs
supported by the 7C0x SmartSwitch, and describes their arrangement in a
series of MIB components. A description of the objects controlled by each
component is also included.

What’s NOT in the 7C0x SmartSwitch User’s Guide . . .

The following standard SPMA tools are available through the 7C0x SmartSwitch
module and are explained in the SPECTRUM Portable Management Application

Tools Guide :

• Charts, Graphs, and Meters

• Community Names

• Global Find MAC Address

• MIB I, II

• MIBTree

• Path

• Telnet

• TFTP Download

• Trap Table

• UPS

Charts, Graphs, and Meters are accessible from the Hub View and the command
line; the Global MAC Address tool is accessible from the Hub View, the platform
console window Tools menu, and the command line; the MIBTree application is
available from the platform console window Tools menu, the Stand-alone
Launcher applications menu, or the command line; and the rest of the tool
applications (except Telnet) are available from the icon menu, the Hub View, or
the command line. (The Telnet application is available only from the icon menu or
the command line.)

Instructions on discovering Cabletron devices, creating icons, and accessing the
icon menus within your management platform are included in your Installing

and Using SPECTRUM for ... guide. If you are using SPMA for the 7C0x

management system — instructions for starting each application from the
command line are included in each chapter of this guide and the SPMA Tools

Guide .

Conventions

SPECTRUM Portable Management Applications — including the 7C0x
SmartSwitch module — can work with a number of different network
management systems running on several different operating systems and
graphical user interfaces. This versatility presents two documentation problems:
first, there is no standard terminology; and second, the appearance of the
windows will differ based on the graphical interface in use. For the sake of
consistency, the following conventions will be followed throughout this and other
SPMA guides.

Introduction to SPMA for the 7C0x SmartSwitch

Screen Displays

SPMA runs under a variety of different operating systems and graphical user
interfaces. To maintain a consistent presentation, screen displays in this and other
SPMA guides show an OSF/Motif environment. If you’re used to a different GUI,
don’t worry; the differences are minor. Buttons, boxes, borders, and menus
displayed on your screen may look a bit different from what you see in the guide,
but they’re organized and labelled the same, located in the same places, and
perform the same functions in all screen environments.

Some windows within SPMA applications can be re-sized; those windows will
display the standard window resizing handles employed by your windowing
system. Re-sizing a window doesn’t re-size the information in the window; it just
changes the amount of information that can be displayed (see Figure 1-1). When
you shrink a window, scroll bars will appear as necessary so that you can scroll to
view all the information that is available.

Conventions 1-5

Use the scroll bars
provided to choose

message history

Figure 1-1. Window Conventions

Some windows will also contain a button; selecting this button
launches a History window (Figure 1-2) which lists all footer messages that have
been displayed since the window was first invoked. This window can help you
keep track of management actions you have taken since launching a management
application.

Figure 1-2. The History Window

1-6 Conventions

Using the Mouse

The UNIX mouse has three buttons. Procedures within the SPMA document set
refer to these buttons as follows:

Introduction to SPMA for the 7C0x SmartSwitch

Button 1

Button 2

Button 3

Figure 1-3. Mouse Buttons

If you’re using a two-button mouse, don’t worry. SPMA doesn’t make use of
mouse button 2. Just click the left button for button 1 and the right mouse button
when instructed to use mouse button 3.

Whenever possible, we will instruct you on which mouse button to employ;
however, menu buttons within SPMA applications will operate according to the
convention employed by the active windowing system. By convention, menu
buttons under the Motif windowing environment are activated by clicking the left
mouse button (referred to as mouse button 1 in SPMA documentation), and there
is no response to clicking the right button (mouse button 3). Under
OpenWindows, menu buttons can be activated by clicking the right button, and
convention dictates that the left button activates a default menu option; within
SPMA, that default option will also display the entire menu. Because of this
difference, references to activating a menu button will not include instructions
about which mouse button to use. All other panels from which menus can be
accessed, and all buttons which do not provide access to menus, will operate
according to SPMA convention, as documented.

Conventions 1-7

Getting Help 1-8

Using the 7C0x SmartSwitch Hub View

Navigating through the Hub View; monitoring hub performance; managing the hub

The heart of the SPECTRUM Portable Management Application (SPMA) for the
7C0x SmartSwitch is the Hub View, a graphical interface that gives you access to
many of the functions that provide control over the 7C0x hub and its installed
modules.

Chapter 2

Using the Hub View

There are two ways to open the Hub View: if you are working within a network
management system, you can select the Hub View option from the icon menu;
specific directions for creating a 7C0x SmartSwitch icon and accessing the icon
menu can be found in the appropriate Installing and Using... guide. If you are
running the 7C0x SmartSwitch module in a stand-alone mode, type the following
at the command line:

spmarun fps <IP address> <community name>

The community name you use to start the module must have at least Read access;
for full management functionality, you should use a community name that
provides Read/Write or Superuser access. For more information on community
names, consult the appropriate Installing and Using... guide, and/or the
Community Names chapter in the SPMA Tools Guide.

NOTES

variables SPMA needs to operate; be sure to use this command any time you launch an
application from the command line. This script is automatically invoked when you launch
an application from the icon menu or from within the Hub View.

If there is a hostname mapped to your 7C0x SmartSwitch’s IP address, you can use
<hostname> in place of <IP address> to launch the Hub View. Please note, however,
that the hostname is not the same as the device name which can be assigned via Local
Management and/or SPMA; you cannot use the device name in place of the IP address.

Navigating Through the Hub View

Within the Hub View, you can click mouse buttons in different areas of the
window to access various menus and initiate certain management tasks. The
following sections describe the information displayed in the Hub View and show
you how to use the mouse to manipulate the Hub View display.

Hub View Front Panel

In addition to the graphical display of the modules installed in your 7C0x
SmartSwitch chassis, the Hub View gives you device level summary information.
The following Front Panel information appears to the right of the module display:

Contact Status is a color code that shows the status of the connection between
SPMA and the device:

• Green means a valid connection.

• Blue means that SPMA is trying to reach the device but doesn’t yet know if the

connection will be successful.

• Red means that SPMA is unable to contact or has lost contact with the device.

Uptime

The time that the device has been running without interruption. The counter
resets to 00:00:00 (HH:MM:SS) when one of the following occurs:

• Power to the device is cycled.

Using the 7C0x SmartSwitch Hub View

NOTE

• The device is reset manually.

Device Name

A text field that you can use to help identify the device; you can assign a device
name via the MIB I, II application (described in the SPMA Tools Guide). To view a
name which is longer than the field, click to place your cursor in the text box, and
use the arrow keys to shift the display.

Device Location

A text field that you can use to help identify the device; you can assign a device
location via the MIB I, II application (described in the SPMA Tools Guide). To
view a location which is longer than the field, click to place your cursor in the text
box, and use the arrow keys to shift the display.

Although you can erase the current name and location and enter new values in the text
fields, you cannot set these values from the Hub View. Any value you attempt to set will
remain in the text field only until the Hub View is closed; to permanently change the
name or location, you must do so via the MIB I, II application.

IP Address

The device’s Internet Protocol address; this field will display the IP address you
have used to create the 7C0x SmartSwitch icon (if you are running the Hub View
from a management platform) or the IP address you used to launch the Hub View
program (if you are running in stand-alone mode). You cannot change the 7C0x
SmartSwitch’s IP address from SPMA.

Using the Hub View 2-3

Using the 7C0x SmartSwitch Hub View

from the Module, Switch, Bridge, Interface, and Port menus, and many can also
be accessed both from the icon menu (if you are running under a network
management platform) and from the command line (if you are running in
stand-alone mode). See Chapter 1, Introduction to SPMA for the 7C0x
SmartSwitch, for a complete list of applications available to the 7C0x
SmartSwitch and how to access each one.

Clicking mouse button 1 on the Quit button closes all Hub View application

Monitoring Hub Performance

The information displayed in the Hub View can give you a quick summary of
device activity, status, and configuration. SPMA can also provide further details
about hub performance via its multi-level menu structure: first, you select the hub
view display mode for the services you want to monitor (Switch, Bridge, or
Interface); then, you can use the available menus (Figure 2-4, below) to access the
tools that let you monitor specific aspects of hub performance and set 7C0x
SmartSwitch operating and notification parameters.

Selecting the Application Display Mode

The device information, menus, and applications that are available to you via the
Hub View depend on the Application Display mode you have chosen. For the
7C0x, you can select from a total of four Application Display modes:

• Switch, which displays switching status in the port displays, and provides
menu access to switch management applications; note that this option is only
available for devices configured to operate in switch mode.

• Bridge, which displays bridging status in the port displays, and provides
menu access to bridge management; note that this option is only available for
devices configured to operate in bridge mode.

• Interface, which displays each port’s MIB II status and statistics.

• None, which removes all interface status information from the Hub View. This
selection primarily effects FDDI modules, whose front panel A and B ports will
continue to display their individual status; Ethernet, Fast Ethernet, and ATM
modules will display as blank under this mode.

You select the Application Display mode you want via the Module menu
(Figure 2-5); note that the Module menu remains the same regardless of which
display mode is selected.

TIP

Figure 2-5. The Hub View Module Menu

Note that, although the Module menu does not change based on the Application Display
mode selected, the ATM option will only appear when a 7A06-01 NIM is installed in the
chassis. See Accessing ATM Management, page 2-28, for more information.

By default, the 7C0x Hub View will launch in Switch display mode (for those
devices configured via Local Management to perform SecureFast switching) or
Bridge display mode (for those configured to perform traditional bridging); to
change this:

1. Click mouse button 1 or mouse button 3 in the Module Index or Module Type
display boxes in the Hub View (see Figure 2-3, page 2-5) to display the
Module menu.

2. Drag down to Application Display, then across to select the display mode
you want. Note that only three selections are available at any one time: either

Bridge or Switch (depending on the device’s current configuration),
Interface, and None.

When you change the application display mode, the port display form will
change to the default form for the chosen mode; you can change the port display
form and access various management applications via each mode’s menu
structure, as described in the following sections.

COM Port and FDDI Front Panel Displays

Note that, like the Module menu, neither the COM port nor the FDDI front panel
displays are affected by changes in the Application Display. The COM port
display always shows each port’s administrative status (ON or OFF), both in the
text display and in the color code (green = ON, blue = OFF); the FDDI front panel
display changes based on the port display form selected via the FDDI menu, as
illustrated below.

TIP

Figure 2-6. COM Port and FDDI Front Panel Displays

Both the FDDI and COM port menus are available and display the same options
in all Application Display modes.

Note that, although the COM port menu does not change based on the Application
Display mode selected, the UPS option will only appear for COM ports which have been
configured for a UPS. See Configuring COM Ports, page 2-36, for more information.

FDDI Port Display Forms

You can display the following information in the front panel port displays for any
installed FDDI NIM:

Admin

Displays the connection state of each port:

• CON (connecting) — the port is trying to establish a link, but has not yet been
successful. Ports which are not connected and which have not been disabled
by management will display this status.

• ACT (active) — the port has been enabled by management and has
successfully established a link.

• SBY (standby) — the port has a physical link, but the SMT Connection Policy
is prohibiting a logical connection to the ring because the attempted
connection is illegal. FDDI protocol always forbids connecting two Master
ports; all other connections are theoretically legal, although some are not

Using the 7C0x SmartSwitch Hub View

desirable. You can view and configure the SMT Connection Policy by selecting
the SMT Connection Policy option on the Module —>FDDI Utilities menu;
see Chapter 4, FDDI Management, for more information.

• DIS (disabled) — the port has been disabled by management; note that this

status does not indicate whether or not there is a physical link connected to the
port.

Port T ype

Displays the media type of each A and B port:

• MMF (multi-mode fiber)

• SMF (single-mode fiber)

• SON (SONET)

• LCF (low-cost fiber)

• TP (twisted pair)

LER Estimate

The Link Error Rate (LER) Estimate port display form displays a cumulative
long-term average of the bit error rate, which represents the quality of the
physical link. It is computed when the port is connected and every 10 seconds
thereafter. The value of the LER Estimate can range from 10

-4

to 10

-15

, but is
always displayed as the absolute value of the exponent: for example, if the port’s
LER Estimate is computed to be 10-5, the value displayed in the Port Status box
will be 5, which represents an actual rate of 1,250 bit errors per second. The lower
LER Estimate numbers represent the highest bit error rates, as summarized in the
figure below:

SMT Index

Displays each port’s logical index number, which reflects the port’s logical
position in relation to the SMT entity to which it is assigned. (Each FDDI interface
has its own SMT entity; these are indexed from left to right in the hub, and from
top to bottom on each module.) Note that the assigned logical index numbers do
not necessarily reflect each port’s physical position on the module or in the hub;
for example, an interface whose physical index is 20002 might have individual A
and B logical indices of 1.1 and 1.2, indicating that the A and B ports which
together form the interface are ports number 1 and 2 assigned to SMT number 1.

For more information on all of these FDDI states, see Chapter 4, FDDI Management.

TIP

FDDI Color Codes

For all FDDI port display forms, the color coding is the same:

• Green indicates that the port is active; this is, the port has been enabled by
management, has a valid Link signal, and is able to communicate with the
station at the other end of the port’s cable segment.

• Blue indicates that the port has been disabled through management, or that it
is in a standby state.

• Yellow indicates that the port is enabled but does not currently have a valid
connection. This usually indicates that the device at the other end of the
segment is turned off, or that no cable segment is attached.

• Red indicates that port is administratively enabled, but not operational due to
some hardware or network problem.

The Switch Application Display

The Switch Application Display — available only for devices which have been
configured (via Local Management) to operate as SecureFast switches — allows
you to view each switch interface according to switching status and statistics; it
also provides access to the Switch menu (Figure 2-8), from which you can launch
a Switch Status window and change the port display form. This is the default
display mode for devices configured for SecureFast operation.

Using the 7C0x SmartSwitch Hub View

Figure 2-8. The Switch Application Display and Menu

For more information about the Switch Status window, see Viewing Switch
Status, page 2-23; port display forms are described below.

Switch Port Display Forms

You can select three port display forms for switch interfaces; note that, although
you can select both Input and Output state for each interface, it is unlikely that
any single interface would have different input and output status values at any
given time.

Admin State

An interface’s Administrative State is the state currently requested by
management; note that this may not always be the same as the actual, or
Operational, state described below:

• ENB (enabled) — the port is administratively enabled.

• DIS (disabled) — the port is administratively disabled.

Oper State

An interface’s Operational State is its actual state; note that this may not always be
the same as the requested, or Admin, state described above:

• ENB (enabled) — the port is enabled.

• DIS (disabled) — the port is disabled.

• PDIS (pending disable) — the port is in a transitional state, moving toward a

state of disabled.

• PENB (pending enable) — the port is in a transitional state, moving toward a

state of enabled.

Monitoring Hub Performance 2-11

Using the 7C0x SmartSwitch Hub View

• INV (invalid configuration) — the port is in an unrecognized state.

• TST (testing) — the port is in a testing mode.

Type

A switch interface’s Type is a dynamic value determined by the type of node to
which the interface is connected:

• Ntwk (network) — a Network interface is connected to another switch.

• Access — an Access interface is connected to an end node (a single user, a
shared resources such as a server or print, or a non-switch shared access
interface such as a bridge).

• Hybrid — though this feature is not yet supported, future firmware versions
will allow a switch interface to service both another switch and an end node.
This kind of configuration could occur, for example, on an FDDI ring.

• GoAcc (going to access) — a transitional state experienced by an interface
which is in the process of switching to access mode.

• Unkn (unknown) — on boot-up, all switch interfaces have a type value of
unknown; this value will convert dynamically as required by the connected
node.

Switch Port Color Codes

The color codes assigned to each port interface in Switch Application mode
indicate the following status conditions:

• Red — the port is administratively enabled, but not operational. This state
generally indicates that a network problem has shut down the port, even
though it is still administratively enabled; it can also indicate an invalid port
configuration.

• Blue — the port is both administratively and operationally disabled.

• Green — the port is administratively enabled and operational.

• Yellow — the port is in a transitional state: an operational status of either
enable or disable is pending, or the port has been administratively disabled,
but is (temporarily) still operational.

• Magenta — the port is in a transitional testing mode.

Note that the color coding scheme is the same regardless of the port display form
selected.

2-12 Monitoring Hub Performance

The Bridge Application Display

The Bridge Application Display — available only for devices which have been
configured (via Local Management) to operate as traditional bridges — allows
you to view each bridge interface according to bridging status and statistics; it
also provides access to the Bridge and Bridge Port menus (Figure 2-9), from which
you can launch the Bridge View application, change the port display form, view a
list of source addresses communicating through a selected interface, and enable
or disable a selected interface. This is the default display mode for devices
configured for traditional bridging.

Using the 7C0x SmartSwitch Hub View

Figure 2-9. The Bridge Application Display and Menus

For more information about the Bridge View application, see Chapter 6, Using the

7C0x Bridge View; for more information about viewing source addresses, see
Viewing the Source Address List, page 2-24; and for more information on
enabling and disabling a bridge interface, see Enabling and Disabling Bridge
Ports, page 2-38. Port display forms are described below.

Bridge Port Display Forms

You can display the following information for each bridging interface:

Admin

Displays the port’s current bridging status:

• FWD (forwarding) — the port is on-line and ready to forward packets from

one network segment to another. Note that this is the default display for ports
which are administratively enabled but not connected.

Monitoring Hub Performance 2-13

Using the 7C0x SmartSwitch Hub View

• DIS (disabled) — the port has been disabled by management; no traffic can be
received or forwarded on this port, including configuration information for
the bridged topology.

• LIS (listening) — 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) — the filtering database is being created, or the Spanning Tree
Algorithm is being executed because of a network topology change. The port
is monitoring network traffic, learning network addresses.

• BLK (blocking) — the port is on-line, but filtering traffic from going across the
7C0x SmartSwitch from one network segment to another. Bridge topology
information is still being forwarded.

• BRK (broken) — the physical interface has malfunctioned.

Tp Frames Forwarded

Displays the percentage of total frames received that were transparently
forwarded across the selected interface.

NOTE

Tp Frames Filtered

Displays the percentage of total frames received that were filtered at the selected
interface.

Sr Frames Forwarded

Displays the rate at which source route frames are being forwarded across the
selected interface, in a frames/second format. Note that this option is currently
grayed out, as no Token Ring NIMs are yet available.

Bridge Port Number

Displays the index number assigned to each bridge port interface. Bridge ports
are indexed from left to right by module, beginning with the module installed in
slot 2; on each module, bridge port numbering follows the physical port indexing.
For example, the port display illustration in Figure 2-9 (page 2-13) contains eight
bridge interfaces: the two interfaces on the FDDI module installed in slot 2 are
bridge port numbers 1 and 2 (corresponding to physical ports 1 and 2); the six
interfaces on the Fast Ethernet module installed in slot 3 are bridge ports 3
through 8 (corresponding to physical ports 1 through 6).

You will note that some Ethernet modules display an upside-down port indexing, with the
highest index numbers at the top of the module, and the lowest ones at the bottom; for
these modules, the bridge port numbers will still follow the physical port indexing, with
the higher bridge port numbers corresponding to the higher physical port indices.
