Hey all,
Sorry about the OT, but I'm having trouble getting some Cisco IP
phones to work correctly with older 2900XL switches. The switches are
the 8 mb variety, and running the latest 12.0 software. The config on
the switch looks like this:
interface FastEthernet0/16
switchport access vlan 251
switchport trunk encapsulation dot1q
switchport voice vlan 252
spanning-tree portfast
Looking around CCO seems to indicate this is the correct way to
do it. From the phone's menu, I can see it's being given VLAN 252 for
it's admin VLAN. But when I look on the switch, the phone's MAC address
shows up in VLAN 251 only. So the phone is being told correctly about
voice VLAN, but it's either not tagging it's traffic with 252 like it
should, or the switch is ignoring it. Any ideas?
Thanks,
Chuck Church
