Configuring a virtual wire includes configuring two Ethernet
ports that use the same link speed as virtual wire interfaces, enabling
link state pass through, and adding each interface to a security
zone. You can optionally create a security policy rule to allow
Layer 3 traffic, and enable multicast firewalling, IPv6 firewalling, LLDP,
and non-IP protocol protection (for PAN-OS 8.0 and later releases).
