I've got a branch office configured to issue IP address from a Cisco Router (IOS 15.0). The router is successfully issuing DHCP addresses just fine. My questions is that when I issue the command "sh ip dhcp binding" it doesn't show the hostnames of the DHCP clients. It does show the IP address and MAC address.

Is there a command I'm missing that would provide this information? I can upgrade the OS on the router if needed to gain this information.

Thanks,

Joe

    `I've got a branch office configured to issue IP address from a Cisco Router (IOS 15.0).` - It's a good thing Cisco only makes 1 router so that we don't have to guess which one you have. – joeqwerty Jul 08 '14 at 16:12
  • It's a Cisco 2911 ISRG2 router – Joe Silver Jul 08 '14 at 18:59

I am 95% sure the DHCP server in Cisco IOS doesn't record this information at all. You'll need to run your DHCP server somewhere else, or collect the hostnames through some other mechanism.

  • Thanks Phil for the response. I was hoping I missed this feature. Kinda funny that my little old linksys WRT54G maintains the hostnames in it's DHCP table :) – Joe Silver Jul 08 '14 at 19:01
