8. Monitoring the Network with SNMP

This chapter explains how to monitor the CrossFire 8600 Token-Ring Switch and/ or the CrossFire 8605 Token-Ring Fiber Switch from a network management system using an application that supports Simple Network Management Protocol (SNMP).

The following topics are described in this chapter:

•

•

•

SNMP setup

IP configuration

SNMP configuration

SNMP Setup

Follow these steps to use in-band management:

1.Attach the switch to the console and start a console session as described in Chapter 5, “Connecting a Network Management Console”.

2.Make the necessary configurations in the IP Configuration screen.

3.Make the necessary configurations in the SNMP Configuration menu and the following subscreens:

•

•

Community String screen

Trap Receiver screen

The following sections describe the SNMP setup screens.

IP Configuration Screen

The IP Configuration screen sets the IP address, gateway address, subnet mask, and IP state.

The IP Address and Default Gateway must be in the same subnet address class— that is, Class A, Class B, or Class C. The system prevents you from entering values from different classes. If you do inadvertently enter an incorrect value, enter 0.0.0.0 in every field, then reenter the correct values.

Refer to Chapter 6, “Switch Configuration” for a complete description on how to configure the IP Configuration menu.
