Solved: DHCP in Router

hs08 · ‎11-29-2022

HI..

How we can query information about DHCP leases from the cisco router? I just want to query active mac addr along with the ip address and hostname?

Hello,

unfortunately, the output of 'show ip dhcp binding' is all the info you get. Hostnames are not shown using the IOS DHCP server...

R1#sh ip dhcp binding
Bindings from all pools not associated with VRF:
IP address Client-ID/ Lease expiration Type
Hardware address/
User name
192.168.1.2 0100.5079.6668.00 Dec 01 2022 08:21 AM Automatic
