You can run "debug ip dhcp server events" and "debug ip dhcp server packets" on the router configured as the server and you will see incoming requests there. Otherwise, bindings is the only place to find it. However, *if* the client is using MAC address to form a client-id, which is not a requirement, it will, as a rule, be <media type><mac address>. For Ethernet (and 802.11[abng]), "media type" will be 01. IOS will then insert dots after every two bytes, so for your CC1E.CC1E.CC1E MAC address, client-id will become 01CC.1ECC.1ECC.1E. -- Marko Milivojevic - CCIE #18427 (SP R&S) Senior CCIE Instructor - IPexpert _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
