Enabling the LLDP Trap Function

Enabling the LLDP Trap Function


The LLDP trap function allows a device to send traps to the NMS in one of the following cases:
  • MDN neighbor information changes.
  • 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 and lldp mdn trap-interval commands. If neighbor information changes frequently, extend the interval to reduce the number of traps, thus suppressing network topology flapping.


  1. Run system-view

    The system view is displayed.

  2. Run snmp-agent trap enable feature-name lldp [ trap-name trap-name ]

    The LLDP trap function is enabled.

    By default, the hwlldpmdnremtableschange trap is disabled, and the lldpremtableschange trap is enabled.

  3. Run commit

    The configuration is committed.
