process-id: OSPF process ID, in the range 1 to 65535.
ifauthfail: Traps for interface authentication failure.
ifcfgerror: Traps for interface configuration error.
ifrxbadpkt: Traps for receiving incorrect packets.
ifstatechange: Traps for interface state change.
iftxretransmit: Traps for the interface to receive and forward packets.
lsdbapproachoverflow: Traps for LSDB to be overflowed.
lsdboverflow: Traps for LSDB overflow.
maxagelsa: Traps for LSA max age.
nbrstatechange: Traps for neighbor state change.
originatelsa: Traps for local LSA generation.
vifcfgerror: Traps for virtual interface configuration error.

virifrxbadpkt: Traps for virtual interface receiving error packets.
virifstatechange: Traps for virtual interface state changes.
viriftxretransmit: Traps for virtual interface receiving and forwarding packets.
virnbrstatechange: Traps for neighbor state change of the virtual interface.
standard: Standard traps.
authentication: Enables the sending of authentication failure traps in the event of authentication
failure.
coldstart: Sends coldstart traps when the device restarts.
linkdown: Sends linkdown traps when the port is in a linkdown status. It should be configured
globally.
linkup: Sends linkup traps when the port is in a linkup status. It should be configured globally.
warmstart: Sends warmstart traps when the SNMP restarts.
system: Sends System (a private MIB) traps.
vrrp: Traps of the VRRP module.
authfailure: Traps for VRRP authentication failure.
newmaster: Enables the sending of VRRP newmaster traps when the device becomes the master.
Description
Use the snmp-agent trap enable command to enable the trap function globally.
Use the undo snmp-agent trap enable command to disable the trap function globally.
By default, the trap function is enabled globally.
Only after the trap function is enabled can each module generate corresponding traps.
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, enable snmp trap updown.
