Usage Guidelines
For Layer 2 traceroute to function properly, Cisco Discovery Protocol (CDP) must be enabled on all of the
devicees in the network. Do not disable CDP.
When the device detects a device in the Layer 2 path that does not support Layer 2 traceroute, the device
continues to send Layer 2 trace queries and lets them time out.
The maximum number of hops identified in the path is ten.
Layer 2 traceroute supports only unicast traffic. If you specify a multicast source or destination MAC address,
the physical path is not identified, and an error message appears.
The
traceroute mac
command output shows the Layer 2 path when the specified source and destination
addresses belong to the same VLAN.
If you specify source and destination addresses that belong to different VLANs, the Layer 2 path is not
identified, and an error message appears.
