Configuring LLDP trapping
LLDP trapping notifies the network management system (NMS) of events such as newly-detected
neighboring devices and link failures.
LLDP traps are sent periodically, and the interval is configurable. To prevent excessive LLDP traps
from being sent when the topology is unstable, set a trap transmission interval for LLDP.
To configure LLDP trapping:
