Command Usage
• An SNMP engine is an independent SNMP agent that resides either on this
switch or on a remote device. 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 remote engine ID is required when using SNMPv3 informs. (See
snmp-server host
on page 4-72.) 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.
• 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 4-81).
