Description
Use the enable snmp trap updown command to enable the trap function for interface state changes.
Use the undo enable snmp trap updown command to disable the trap function for interface state
changes.
By default, the trap function for interface state changes is enabled.
Note that:
To enable an interface to generate linkUp/linkDown traps when its state changes, you need to enable
the linkUp/linkDown trap function on the interface and globally. Use the enable snmp trap updown
command to enable this function on an interface, and use the snmp-agent trap enable [ standard
[ linkdown | linkup ] * ] command to enable this function globally.
Related commands: snmp-agent target-host, snmp-agent trap enable.
