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 5-byte to 32-byte hexidecimal value. Separate each byte with a colon. Do not all 00s or all FFs. Example: 00:00:00:09:0a:fe:ff:12:97:33:45:12.
IMPORTANT:
Important: The last byte of the engine ID must not
be greater than EE. If you enter a value
greater than EE, you may not be able to
access the ATM Uplink module
MIBs.
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. EE is the greatest value that allows for the addition of any one of the 17 slots.
