====== Layer 2 Traceroute ====== {{tools:l2trace.png|}} Use this tool to trace layer 2 network paths between hosts. Usage is: * Enter a hostname or IP address and trace up to its router. * Optionally enter a destination hostname or IP address and trace between the two. The result shows layer 2 (switch) hops as "level L2" and router hops as "level L3". For each hop incoming and outgoing interface is displayed.
