        w - waiting to be aggregated
Number of channel-groups in use: 6
Number of aggregators:           6

Group  Port-channel  Protocol    Ports

  1. […] admin added an interesting post on HowTo: Find switchport for a MAC Address on a Cisco Catalyst SwitchHere’s a small excerpt […]

  2. Have you tried ZipTie? It’s an open source network management program that does this kind of stuff for breakfast! :-) Seriously, like right-click on a switch and run the Switchport/MAC mapping tool, view the results. Then even type in an IP address and it will tell you which MAC it is and which switchport it is connected to. Talk about handy for finding which port a desktop machine is connected to!

    I noticed you also had a blog about how to show chassis serial number and part numbers. ZipTie captures all that too along with backing up your device configurations. And it supports not just IOS, but Juniper, Nortel, Radware, Force10, and a bunch of equipment providers.

    I know all this because I work on the ZipTie project! :-)

    Seriously, we’re awesome. No network engineer should be without us.

  3. Hi,

    Thanks for the input. I’ve been watching and evaluating Ziptie for quite sometime…Was just going to do a write up on ziptie and other similar tools (all opensource). You just got here early 😉

    Ziptie is a great product, great framework!!!!


  4. Cool! step. Thnks from Thai-Network Admin.

  5. how to bind an public Ip with the MAC address in either Cisco switch 2960 or Cisco Router 1842 series

  6. I’ve read many of these articles explaining this process but where I always have trouble is obtaining the correct MAC address. From the core switch, when I perform a sh ip arp 10.x.x.x I get a blank response. When I try this from a distribution switch, I get a MAC address in return, but not the MAC of the actual system I’m trying to locate. I believe it’s the MAC address of the etherchannel Po1 that’s being returned. I verified this by RDP’ing to the actual system and verifying it’s MAC address, but many times, this is not possible. Argghhh, might have to look into this ziptie thing. :)

  7. thanks
