Configuring SNMP (CLI)

This section provides information about the commands you use to manage

and view SNMP features on the switch. For more information about these

commands, see the

Reference Guide

To use SNMPv3, the switch must have engine ID. You can specify your own

ID or use the default string that is generated using the MAC address of the

switch. If the SNMPv3 engine ID is deleted, or if the configuration file is

erased, then SNMPv3 cannot be used. Since the EngineID should be unique

within an administrative domain, the following guidelines are recommended:

For standalone switches use the default keyword to configure the Engine

For a stack of switches, configure your own EngineID, and verify that is

unique within your administrative domain.

Changing the value of SNMP EngineID has important side-effects. A user's

password (entered on the command line) is converted to an MD5 or SHA

security digest. This digest is based on both the password and the local engine

ID. The command line password is then destroyed, as required by RFC 2274.

Because of this deletion, if the local value of engineID changes, the security

digests of SNMPv3 users will be invalid, and the users will have to be

reconfigured.

Beginning in Privileged EXEC mode, use the following commands to

configure an engine ID for SNMP.
