About the LLDP protocol
The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol in the Internet Protocol Suite used by network devices for advertising their identity, capabilities, and neighbors on an IEEE 802 local area network, principally wired Ethernet.
LLDP performs functions similar to several proprietary protocols, such as the Cisco Discovery Protocol (CDP) ect.
When enabled on the Palo Alto Networks firewall within an interface...
The other peers will not be able to see any infomation related to the Palo Alto Networks firewall such as system name, port despcription, etc. until we enable it globally.
Make sure you also have enabled LLDP globally to make this protocol work.
