I setup a test lab for our to be 6.(1a) machines. Setup went just fine.
I set the switchports up just like they are on our production servers with:
switchport access vlan 172
spanning-tree port fast
However, as soon as I enable the "switchport access vlan 172" I can't connect to the CUCM web admin. The phones register, but I can't access the admin.
If I remove the "switchport access vlan 172" the phone unregisters but I can access the web admin.
Besides the ports that the CUCM servers are in, the rest of the ports are set to "switchport voice vlan 172", "switchport mode trunk", and "switchport trunk encapsulation dot1q"
What am I doing wrong here? The ports are setup exactly the same as they are in our 4.x production domain.
