Global Configuration
Command Usage
• An SNMP engine is an independent SNMP agent that resides either on
the ECN330-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
in section 7.6.6 on page 615.) 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. Therefore, the
remote agent’s SNMP engine ID must be configured before sending
proxy requests or informs to it.
• A local engine ID is automatically generated that is unique to the
ECN330-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. All
existing users will need to be reconfigured (section 7.6.14 on page 628).
