Enabling the LLDP Trap Function

The LLDP trap function allows a device to send traps to the NMS in one of the following cases:

The LLDP function is enabled or disabled globally.
The local management address changes.
The rate of LLDPDUs received by an interface exceeds the alarm threshold.
A neighbor is added, deleted, aged out, or packets from the neighbor are discarded.

The LLDP trap function applies to all interfaces. The LLDP trap function takes effect regardless whether LLDP is enabled globally.
If the network topology is unstable, disable the LLDP trap function to prevent frequent trap sending.
To set the interval for sending neighbor change traps to the NMS, run the lldp trap-interval commands. If neighbor information changes frequently, extend the interval to reduce the number of traps, suppressing network topology flapping.

Run system-view
The system view is displayed.
Run snmp-agent trap enable feature-name lldptrap [ trap-name { hwlldpdisabled | hwlldpenabled | hwlldplocmanipaddrchange | hwlldprateexcessive | lldpremtableschange } ]
The LLDP trap function is enabled.

By default, the LLDP trap function is enabled.
