Hi,  We are working on a project that will re do all our dhcp scopes. We are a developement company and have about 1/2 the machines on DHCP and the other 1/2 have static addresses. what we are trying to do is get a list of hostnames for each floor.  We have Cisco switches and routers on every floor.

I was wondering if any one knows of a good tools that may be able to map host names from the switch on each floor. not necesarly from the core router.  Or even more advanced Cisco commands that may work.
 
I could do it manually by getting the mac address table off the switch then arp all the address one by one. Just hopeing to find an easier solution

thanks for the help

If you have cisco works (CWLAN), you can use the tool called User Tracking.  It will do exactly what you are looking for.    If you don't have cisco works, then I would recommend writing a quick script to merge the CAM entries with the ARP tables.  You could also use excel VLOOKUP to map the CAM entry to a ARP/IP entry.
