I heard that IOS DHCP Server does not actually support Option 60, i.e. it offers option 43 regardless of configured option 60.

I'm trying to use my 3560E as the DHCP server. It works fine just doing option 43. But when I try and throw in option 60 to target a specific AP model, it still advertises the controller IP to all models. I have verified this with a packet capture showing the DHCP option 43 info in the DHCP ACK packet from the switch. My setup is a 3560E layer 3 switch with a 1131, 1142, 1242, and 2- 1252 APs. The DHCP config is shown below. I did try 2 different revs of code in case it was a bug (12.2.44 SE# and 12.2.58 SE#). When all 5 APs boot, they all get the option 43 info. Can anyone see if I'm doing something wrong? Has anyone else made this work as advertised in IOS? ip dhcp excluded-address 10.10.114.1 10.10.114.99 ip dhcp excluded-address 10.10.114.160 10.10.114.255 ip dhcp pool vlan114 network 10.10.114.0 255.255.255.0 default-router 10.10.114.1 option 43 hex f104.0a0a.700a dns-server 10.10.210.6 domain-name rensink.local option 60 ascii Cisco AP c1250 Jeff Rensink _______________________________________________ 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?
