Setting a 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.
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 engineID is deleted
or changed, all SNMP users will be cleared. You will need to reconfigure all
existing users.
A new engine ID can be specified by entering 10 to 64 hexadecimal
characters. If less than 26 characters are specified, trailing zeroes are added
to the value. For example, the value “1234” is equivalent to “1234”
followed by 60 zeroes.
Web – Click SNMP, SNMPv3, Engine ID. Enter an ID of up to 64
hexadecimal characters and then click Save.
