    TraceMAC - Traceroute for MAC addresses

    TraceMAC - Traceroute for MAC addresses

    TraceMAC is a command-line Layer 2 traceroute for Cisco switches

    TraceMAC is a Windows/Linux command-line tool that allows you to trace a specific MAC address thru Cisco switches. 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 it finds the switch where that MAC address (PC/Printer/Etc) is directly connected. 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...
