The Layer 2 traceroute utility identifies the Layer 2 path that a packet takes from a source device to a destination device. Layer 2 traceroute supports only unicast source and destination MAC addresses. The utility determines the path by using the MAC address tables of the switches in the path.

It works by connecting to a switch using SSH, SNMP, Telnet, HTTP or HTTPS and do some "show commands" and later process the output, this will happen recursively until.
Is there a utility or application that can work like Tracert which can give us all the MAC address hops This is effectively the tracert in layer Layer 2 traceroute.

Available on most operating system, traceroute works at the network layer (layer 3) of an IP Network and it returns the list of routers a connection must pass through to get to its destination. 12 Jan - 3 min - Uploaded by ciscozine The traceroute mac command output shows the Layer 2 path when the specified source and.
