Setting the
Local Engine ID
Use the Administration > SNMP (Configure Engine - Set Engine ID) page to change
the local engine ID. An SNMPv3 engine is an independent SNMP agent that resides
on the switch. This engine protects against message replay, delay, and redirection.
The engine ID is also used in combination with user passwords to generate the
security keys for authenticating and encrypting SNMPv3 packets.
Command Usage
A local engine ID is automatically generated that is unique to the switch. This is
referred to as the default engine ID. If the local engine ID is deleted or changed, all
SNMP users will be cleared. You will need to reconfigure all existing users.
Parameters
These parameters are displayed:
◆
Engine ID – A new engine ID can be specified by entering 9 to 64 hexadecimal
characters (5 to 32 octets in hexadecimal format). If an odd number of
characters are specified, a trailing zero is added to the value to fill in the last
octet. For example, the value “123456789” is equivalent to “1234567890”.
◆ Engine Boots – The number of times that the engine has (re-)initialized since
the SNMP Engine ID was last configured.

1.
