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).
