Introduction

How to use this guide; related guides; software conventions; getting help; 9H42x-xx firmware versions
Welcome to the Cabletron Systems MMAC-Plus Remote Management for the
9H42x-xx Series Fast Ethernet SmartSwitch™ Modules User’s Guide. We have
designed this guide to serve as a simple reference for using SPECTRUM Element
Manager for the 9H42x-xx family of Fast Ethernet SmartSwitch Modules for the
MMAC-Plus. These modules provide Fast Ethernet connectivity to the Internal
Network Bus (INB) backplane via high-speed packet switching, as well as RMON
management, Broadcast Storm Protection, and upcoming SecureFast Virtual
Networking features.
The information presented in this guide covers the following 9H42x-xx devices:
The 9H421-12 module provides 12 fixed multi-mode fiber 100 Mbps interfaces,
each with SC connectors.
The 9H422-12 module provides 11 fixed 10/100 RJ-45 connections for
category 5 twisted pair, and one media-flexible interface designed to accept a Fast Ethernet Port Interface Module (FEPIM). 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 9H423-26 module provides 24 fixed 10/100 interfaces via two RJ71
connectors, and two fixed multi-mode fiber interfaces, each with SC connectors. Support for this device is beta-quality only.
The 9H423-28 module provides 28 ports of mixed 10/100 connectivity: 24
standard Ethernet (10Mbps) interfaces via two RJ71 connectors; two 10/100 interfaces via two fixed RJ45 connectors; one fixed multi-mode fiber Fast Ethernet interface (with an SC connector); and one slot for an FEPIM module.
And finally, the 9H429-12 module provides 12 fixed single-mode fiber Fast
Ethernet interfaces, also with SC connectors.
1-1
Introduction
Each front-panel port (regardless of media type or bandwidth capability) can be configured to operate in Full Duplex Switched Ethernet (FDSE) mode. FDSE allows for each 10BaseT port to provide dedicated 20-Mbps bandwidth for connections to file servers or high-end workstations, while 100BaseTX or 100BaseFX ports can be used to deploy fault-tolerant 200-Mbps backbone links. All 100BaseTX ports also support auto-negotiation.
The 9H42x-xx modules support two types of packet switching:
Traditional switching, which is 802.1d bridging based on physical layer address
information; it enhances the overall reliability of the network and, with DEC
Spanning Tree support, protects against loop conditions.
SecureFast™ switching, which is high-performance switching based on source
and destination MAC (physical) layer addresses. Packets received from a
source address on a module’s protocol-dependent front panel network are
converted into fixed-length, protocol-independent packets for transmission
across a backplane, and then are re-converted at the destination device into the
appropriate physical frame format for reception by the destination address.
Future firmware and management software enhancements will allow an
administratively defined connection-policy between end stations connected to
SecureFast Packet Switching devices.
NOTE
Firmware support for the SecureFast Virtual Networking (SFVN) feature of the 9H42x-xx family (which allows switching configuration on a per-user level) is in the early stages of release as this document is published; SFVN remote management will be included in a future release of SPECTRUM Element Manager.
Each module also provides a single backplane interface to the INB bus, for common transmission of data with all other modules of any media connected to the INB in the chassis. The INB is the Cabletron-proprietary network bus for protocol-independent, high-speed packet or cell switching between connectivity modules that support front-panel Ethernet, FDDI, Token Ring, or ATM networks. The connectivity modules incorporate Cabletron’s SecureFast Switch (SFS) technology to provide high-performance packet switching based on source and destination MAC addresses, rather than on internet protocol (IP) addresses. By basing packet switching on physical layer information, the INB allows your network infrastructure to be protocol independent. The INB backplane consists of two channels (INB-1 and INB-2), each featuring a 64-byte wide data path capable of a sustained data transfer rate of 2 Gigabits/second (4 Gigabits/second for the combined channels); all 9H42x-xx modules connect to INB-2. The INB backplane requires no management, as its data transmission is subject to hardware defaults.

Using the 9H42x-xx User’s Guide

Remote management for the 9H42x-xx family of modules is available from two
main resources: the MMAC-Plus Chassis View application, which displays and
provides management for an MMAC-Plus chassis (and its installed modules); and
the individual Module Views, which provide management for single modules.
This guide contains information about software functions accessed directly from
an individual Module View; for information about monitoring and controlling a
configured MMAC-Plus chassis, see the Using MMAC-Plus Remote Management
User’s Guide included with your software. Additional management information
about tools and features common to many devices can also be found in the
Installing and Using SPECTRUM Element Manager guide, the SPECTRUM
Element Manager Tools Guide, and the Remote Administration Tools User’s
Guide.
Note that, since the management functionality available for each module in the
9H42x-xx family is virtually identical, the modules will be referred to collectively
here as the 9H42x-xx.
This manual contains the following information:
Chapter 1, Introduction, provides a list of related documentation, describes
certain software conventions, and shows you how to contact Cabletron Systems’
Global Call Center.
Introduction
Chapter 2, The 9H42x-xx Module View, describes the visual display of the
9H42x-xx modules and explains how to use the mouse within the Module View;
the operation of several module-level management functions — such as changing
the module display, enabling and disabling ports, and setting device date and
time — is also described here.
Chapter 3, Alarm Configuration, provides instructions for using both the Basic
and Advanced alarm applications to configure both alarms and the events that
notify you that an alarm condition has occurred. The ability to automatically
initiate a SET or a series of SETs in response to an alarm — functionality provided
by Cabletron’s proprietary Actions MIB — is also described.
Chapter 4, Statistics, describes the two statistics views available at the interface
level: MIB-II Interface statistics, and RMON statistics.
Chapter 5, Bridging, provides a comprehensive look at all management options
associated with the traditional switching — or bridging — functionality currently
available on all front panel interface ports, including Bridge Performance Graphs,
Spanning Tree, and the Filtering Database.
We assume that you have a general working knowledge of Ethernet and Fast
Ethernet IEEE 802.3 type data communications networks and their physical layer
components, and that you are familiar with general bridging and switching
concepts.

Port Status Displays

When you open the Module View window, each port will display its current bridging state (defined below); to change this status display, select one of the options on the Port Status menu, as described in the following sections.
For all 9H42x-xx modules, the port text box indexed “1” indicates the fixed interface to
TIP
the INB-2 backplane bus; interfaces indexed “2” through “xx” indicate the front panel switching interfaces.
2-8 Viewing Module Information
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 Module Vie w window; a
menu will appear.
2. Drag down (and to the right, if necessary) to select the status information you
want to display. The port text boxes will display the appropriate status information.
Port status view options are:
Status
You can view four port status categories, as follows:
Bridge — FWD, DIS, LRN, LIS, BLK, or BRK
Bridge Mapping
Admin — ON or OFF
Operator — ON or OFF
If you have selected the Bridge status mode, a port is considered:
The 9H42x-xx Module View
FWD (Forwarding) if the port is on-line and ready to forward packets across
the 9H42x-xx from one network segment to another. Note that this is also the default display for ports which are administratively enabled but not connected.
DIS (Disabled) if bridging at 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) 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
9H42x-xx from one network segment to another. Bridge topology information will be forwarded by the port.
BRK (Broken) if the physical interface has malfunctioned.
If you have selected Bridge Mapping, the port status boxes will display the bridge interface index numbers assigned to each interface (which may or may not match the ifIndex values displayed via the I/F Mapping option described below).
Viewing Module Information 2-9
The 9H42x-xx Module View
If you have selected the Admin status mode, a port is considered:
ON if the port is enabled by management.
OFF if it has been disabled through management action.
Note that 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.
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.
NOTE
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 or 100 Mbits/sec) 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.
In SPECTRUM Element Manager, the polling interval is set using the Tools—>Options window available from the primary window menu bar, or via the individual device icon’s Properties window. Refer to the Installing and Using SPECTRUM Element Manager guide for full information on setting device polling 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 9H42x-xx module. Note that this value may or may not correspond to the bridge port index displayed via the Bridge Mapping option (described above).
2-10 Viewing Module Information
I/F Speed
If you choose the I/F Speed mode, the interface boxes will display the bandwidth of each individual interface on the 9H42x-xx module: 10M (megabits) for standard Ethernet; 100M for Fast Ethernet; and 2500M for the INB backplane interface.
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 9H42x-xx module: Eth (ethernet-csmacd) or Other (for the INB backplane interface). Note that there is no type distinction between standard Ethernet and Fast Ethernet.
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).
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.

The Chassis Manager Window

Like most networking devices, Cabletron’s devices draw their functionality from a collection of proprietary MIBs and IETF RFCs. In addition, Cabletron’s newer intelligent devices — like the 9H42x-xx 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, 9H42x-xx bridging information is organized into its own component; more generic device and port information resides in the chassis component. Note, too, that there is no one-to-one correspondence between MIBs and MIB components; a single MIB component might contain objects from several different proprietary MIBs and RFCs.
The Chassis Manager window, Figure 2-3, is a read-only window that displays the MIBs and the MIB components — and, therefore, the functionality — supported by the currently monitored device.
