MAC MAC ADDRESS LOOKUP CODE

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.īelow 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. If the OUI or MAC address is in the Wireshark Database, the result provides extra details that help identify its application or actual vendor instead of the original assignmentĭetermines if the MAC address is a multicast or unicast addressĬhecks if the MAC address is universally or locally administeredĬhecks if the assignment block size is large, medium, small, or individual.Traceroute is a tool for measuring the route path and transit times of packets across an Internet Protocol (IP) network.

If the MAC address and its range is reserved for a specific use case by the vendor, the result will show the higher-level protocol encapsulated in the frame Obtains the Left and Right borders, total number of MAC addresses, and assignment type of the MAC address block a specific MAC address belongs toĭetects if the MAC address is assigned to a virtual machine, in which case the vendor’s name (e.g., VMWare) is given if the MAC address does not belong to a virtual machine, the result says “Not detected” Identifies if the MAC address belongs to a privately registered MAC address block The dates when the MAC address block a particular MAC address is part of was registered and last updatedĭetermines if the MAC address belongs to any registered MAC address blockĬhecks if the syntax of the MAC address of interest is correct
