2336 CHAPTER 154: SNMP CONFIGURATION COMMANDS
Parameter None
Description Use the
enable snmp trap updown command to enable the sending of Trap
messages for interface state change (linkup/linkdown Trap messages).
Use the
undo enable snmp trap updown command to disable the sending of
linkup/linkdown SNMP Trap messages on an interface.
By default, the sending of linkup/linkdown SNMP Trap messages is enabled.
Note that:
To enable an interface to send SNMP Trap packets when its state changes, you
need to enable the Link up/down Trap packet transmission function on an
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 command: snmp-agent target-host, snmp-agent trap enable.
