A couple of months ago I upgraded our 2 old 6500 to a pair of 6509's running as a Virtual Switching System. I use this VSS for core routing/switching for all internal LAN traffic. Since this upgrade, I am no longer able to use host names while using the User Tracking utility. User tracking still works with MAC & IP address, just not with the hostname anymore.
I found a previous thread that I test my resolver.pl. If I use resolver.pl with the IP address, it returns just the IP address, not the hostname. If I use resolver.pl with the hostname, it returns the hostname and IP address.
CM version: 5.1.4
VSS IOS version: 12.2(33) SXI
Any help is appreciated.
This points to a problem getting the ARP information from the associated router. Which device should have the ARP entry for 00-21-70-14-62-ac? Is it the VSS itself? If so, do an SNMP Walk on the ipNetToMediaTable. You need to be able to find an entry for 00-21-70-14-62-ac.
