Changing the Engine ID of the Switch

Changing the Engine ID of the Switch

You can override the default engine ID, which is based on the IP address of the switch. After changing the engine ID, however, you must change all SNMPv3 user passwords. For information on changing SNMPv3 user passwords, see "Changing a User Password."

*Important: Each switch must have a unique engine ID. If you change the default engine ID of a switch, make sure that no duplicates exist in your network.

To change the engine ID of the switch, use the following CLI command:

(configure)# snmp-server engineid [<engine-Id>]

Table�5-3 provides an explanation of the command variable.

Table 5-3. snmp-server engineid Command
Parameter	Definition
<engine-Id>	A 12-byte hexidecimal value. Separate each byte with a colon. Do not use all 00s or all FFs. Example: 00:00:00:09:0a:fe:ff:12:97:33:45:00. Important: The last byte of the engine ID must be 00. This restriction makes SNMP access to the ATM Uplink module possible. The engine ID of an ATM Uplink module is the engine ID of the switch, where the slot number of the ATM Uplink module is added to the last byte.
