To avoid management systems attempting to manage a partially booted system, SNMP will remain in a shut down state if the configuration file fails to complete during system startup. While shutdown, SNMP gets and sets are not processed. However, notifications are issued if an SNMP trap group has been configured.
To enable SNMP, the portions of the configuration that failed to load must be initialized properly. Start SNMP with the config>system>snmp>no shutdown CLI command.
Use caution when changing the SNMP engine ID. If the SNMP engine ID is changed in the config>system>snmp> engineID engine-id context, the current configuration must be saved and a reboot must be executed. If not, the previously configured SNMP communities and logger trap-target notify communities will not be valid for the new engine ID.
SNMP dying gasp uses system IP to send out packet. Therefore, the system IP must be configured before configuring SNMP dying gasp.
