COMMAND TO SHOW MAC ADDRESS MAC

вЂ¦ and to have more detail about the trace use the вЂdetailвЂ™ option: Ciscozine-SW1#traceroute mac ip 192.168.0.4 192.168.0.6 detail In the first case, use the command вЂtraceroute mac 0019.9955.0f60 0bвЂ™ Ciscozine-SW1#traceroute mac 0019.9955.0f60 0b You have two options to find the path between two hosts: Protocol Address Age (min) Hardware Addr Type Interface Total Mac Addresses for this criterion: 6 Suppose to have two host (192.168.0.4, 192.168.0.6) and you would find the layer2 path using the Ciscozine-SW1 Switch.Д«elow the MAC address table and the ARP table of the Ciscozine-SW1 switch: Ciscozine-SW1#sh mac-address-table dynamic

See you the example to understand how this feature works. If you specify source and destination addresses that belong to different VLANs, the Layer 2 path is not identified, and an error message appears. The traceroute mac command output shows the Layer2 path when the specified source and destination addresses belong to the same VLAN. To do it, Cisco has implemented a good tool: traceroute mac. In a Data Center, it is often required to find a host and the layer2 path. Routers decrement this parameter and discard a packet when the TTL value has reached zero, returning an ICMP error message (ICMP Time Exceeded) to the sender. Tracing the intermediate routers traversed involves control of the time-to-live (TTL) Internet Protocol parameter.

Traceroute sends a sequence of Internet Control Message Protocol (ICMP) packets addressed to a destination host. Traceroute is a tool for measuring the route path and transit times of packets across an Internet Protocol (IP) network.
