Use the LLDP-V2-MIB to monitor Link Layer Discovery
Protocol (LLDP) events. For example,
you can check the lldpV2StatsRxPortFramesDiscardedTotal object to
see the number of LLDP frames that were discarded for any reason.
The Palo Alto Networks firewall uses LLDP to discover neighboring
devices and their capabilities. LLDP makes troubleshooting easier,
especially for virtual wire deployments where the ping or traceroute utilities
won’t detect the firewall.
Palo Alto Networks firewalls support all the LLDP-V2-MIB objects
