• A remote engine ID is required when using SNMPv3 informs. (See
snmp-server host on page 4-155.) The remote engine ID is used to
compute the security digest for authenticating and encrypting packets
sent to a user on the remote host. SNMP passwords are localized using
the engine ID of the authoritative agent. For informs, the authoritative
SNMP agent is the remote agent. You therefore need to configure the
remote agent's SNMP engine ID before you can send proxy requests
or informs to it.
• Trailing zeroes need not be entered to uniquely specify a engine ID. In
other words, the value "1234" is equivalent to "1234" followed by 22
zeroes.
• 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 (page 4-166).
Example
Console(config)#snmp-server engine-id local 12345
Console(config)#snmp-server engineID remote 54321 192.168.1.19
