An un healthy tunnel will either show “There are presently no active sessions” or it might show some TX or RX, but not both. The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. All I need is the mac address of the Vlan for the outside interface. The Windows ARP tool helps to display and modify the ARP table on the system.
