#Mactrack login mac#
Have a script that logs in to each one of your edge devices and grabs the MAC address tables off of them.
There are a couple of ways to do this on the cheap (the exercise of research and/or implementation I'll leave up to you). I've tried "show ip dhcp binding | inc " it gives me a strange MAC (with 2 extra characters) that is not the associated device MAC, I have not looked into this yet, but ARP is accurate and I'm more concerned with finding the switch port the offending machine is connected to. I try to provide some management and a bit of security. There is no central DNS or Active Directory it is like a Guest Network, where only internet access is provided. because my approach only works while the user is still connected, and no value when i review the logs in the morning, but the device is no longer connected. Specifically I'm looking for the switch-port the user is connected to ? also some history would be great. In an all Cisco shop, with minimal budget using Cisco switches, there must be a more efficient way to track down host machines ? Huge VLANs (/16) with a few hundred users on each VLAN Sometimes this can take logging in to ~7 switches, there are specific challenges to this network that I can do nothing about at the moment. logon to that switch rinse and repeat until I locate the workstation.Mac address lookup to see which switch it was learned from.Logon to a core switch in the same VLAN.I sometimes need to do this, if a workstation IP address, shows up on an ACL Deny What is the best method of locating a particular workstation on a VLAN ?
