n
The configuration does not apply to LLDP-CDP packets, which use only SNAP
encapsulation.
Configuring LLDP Trap LLDP trap is used to notify NMS of the events such as new neighboring devices
detected and link malfunctions.
LLDP traps are sent periodically and you can set the interval to send LLDP traps. In
response to topology changes detected, a device sends LLDP traps according to
the interval configured to inform the neighboring devices of the changes.
Follow these steps to configure LLDP trap:
