LLDP over a Virtual Wire

Virtual wire interfaces can use LLDP to discover neighboring devices and their capabilities, and LLDP allows neighboring devices to detect the presence of the firewall in the network. LLDP makes troubleshooting easier especially on a virtual wire, where the firewall would typically go undetected by a ping or traceroute passing through the virtual wire. LLDP provides a way for other devices to detect the firewall in the network. Without LLDP, the presence of a firewall through the virtual wire link is practically undetectable to all network management systems.
