CAUTION:
The maximum TTL value that CDP allows is 255 seconds. To make CDP-compatible LLDP work properly
with Cisco IP phones, be sure that the product of the TTL multiplier and the LLDPDU transmit interval is less
than 255 seconds.
Configuring LLDP trapping
LLDP trapping notifies the network management system (NMS) of events such as newly-detected
neighboring devices and link malfunctions.
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 transmit interval for LLDP.
Follow these steps to configure LLDP trapping:
