TraceMAC is a Windows/Linux command-line tool that allows you to trace a specific MAC address thru Cisco switches.

Note: It works with Cisco switches only and you must have CDP enabled at least on trunks/links between switches! Is tested with Cisco switches: Catalyst: 2960,3560,3750,4948,6509,9200,9300,9500 (All protocols) Nexus: C9332C, 93180YC-EX (NX-OS SSH) Express 500 (HTTP) FYI: It uses Nbtscan.exe (NetBIOS) as a alternative method to discover the mac address of a host and now seems that it is considered a malware. Anyway it is just a simple network tool that can scan the network similar to NMAP or Angry IP Scanner, etc...
