Introduction

The 9T122-24 MicroLAN™ Switch Module, shown in Figure 1-1, is a three port Token Ring bridge and router module. This module supports either one token ring with 24 HUB connections, or two separate Token Rings with 12 HUB connections, and an interface to the FNB backplane.

Chapter 1

Features

Processor

The 9T122-24 is equipped with an advanced Intel i960 microprocessor. This microprocessor provides a platform for all management functions within a scalable RISC-based architecture.

System Management

Interfaces to the two System Management Buses (SMB-1 and SMB-10) for intermodule management.

Connectivity

The 9T122-24 provides 24 RJ-45 Trunk Coupling Unit (TCU) lobe connectors. The connectors may be conﬁgured as one 24-port ring (

Bridging/Routing

Bridging/Routing between the front panel Token Ring connections and/or to any other module in the chassis via FNB-1 or FNB-2 of the FNB bus. The module is capable of Transparent Bridging or Source Route Bridging. IEEE 802.1d Spanning Tree Protocol is supported in all bridging functions. Translational bridging between Source Routing and Transparent Frames types is also performed.

default ) or two 12-port rings.

Introduction

NOTE

Management Information Base (MIB) Support

The 9T122-24 module provides MIB support including:

• IETF MIB II (RFC 1213)

• IETF RMON MIB (RFC 1271 and 1513)

• IETF Bridge MIBs (RFC 1493 and 1525)

• IEEE 802.5 Token Ring MIB (RFC 1231)

• Cabletron Enterprise MIBs

For a complete list of supported MIBs, refer to the release notes provided in the module package.

Ring Security

This feature prevents unauthorized stations from attaching to the ring. Using Local or Remote Management, the module may be conﬁgured as to which MAC addresses are allowed to operate on the ring.

Multi-Ring Out Capability

With this feature any port of the module may be conﬁgured as a ring-out port through management software. In this conﬁguration a stand-alone passive concentrator (such as an IBM 8228 MAU) may be added to the ring.

Telnet

A telnet session can be set up with the module to provide access to the Local Management screens.

LANVIEW LEDs

The 9T122-24 use LANVIEW – the Cabletron Systems built-in visual diagnostic and status monitoring system. With LANVIEW LEDs, you can quickly identify the device, port, and physical layer status at a glance.

Hot Swapping

The 9T122-24 can be installed or removed from the chassis while the SmartSwitch 9000 is powered up without affecting the operation of the remaining modules in the chassis.
