Cabletron Systems STH-24

Introduction

1-2

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

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.

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

module package.
