I'm setting up my CCIE lab, I get my CUCM and CME working no issues with IPC.
Then I get to the second portion, add a CME with a couple of 7940's, they won't get DHCP? So I try everything and finally remove the switchport voice Vlan command and then they start working.
CDP is enabled, I can ping the CME / DHCP server and it's not on a subdot1Q because I got frustrated and flattend the network . Checked spanning tree (Or what passed as spanning tree on this switch).. Check all sorts.
It was kind of obvious I wouldn't need voice vlan once I flattend it, I did try a trunk,
Config was just standard stuff I've done hundered's of times, just got the 3524XL today. I suppose I've been pampered in the work place with 3750's and Catk 6 / 4K's.
I had a 1760, Vlan DB on both (Vlan 100) subdot1Q fa0/0.100 (encapsulation dot1q 100) on the 1760 with an IP address. From this I could ping everywhere (PC etc.), the basic setup is switch and router with a router on stick config with DHCP set up. Nothing more, I tried switchport voice vlan 100 and still nothing more. Switchport voice vlan and dot1p is part of Cisco official documentation, after I flattend the network just testing I tried dot1p as well. Oh I also had an IP helper, used the native switch IP DHCP server command etc. etc.
