Usage Guidelines
For Layer 2 traceroute to function properly, Cisco Discovery Protocol (CDP) must be enabled on each device
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.
The traceroute mac ip command output shows the Layer 2 path when the specified source and destination
IP addresses are in the same subnet.
When you specify the IP addresses, the device uses Address Resolution Protocol (ARP) to associate the IP
addresses with the corresponding MAC addresses and the VLAN IDs.
• If an ARP entry exists for the specified IP address, the device uses the associated MAC address and
identifies the physical path.
