[cisco-voip] 7960 PC port

[Ed Leatherman]

This is interesting. I had been setting up trunk interfaces for the phones
on 3524XL's while we were using them... I went back to my training lab
manuals and that is how they explained to do it so I guess I never really
checked any other way until the 3550 models came out.

So I went in the lab and dug up one of those models and tried it out, to my
surprise it works the "Correct" way as well as trunked, which I did not
expect. Since we were told to program trunk ports for the 3524 I assumed it
was because the other way wouldnt work.

But we still dont know why Peter's PC/phone wont come up on that switchport
:)
- If you dont have any CDP config on the interface, that would indicate to
me that CDP is enabled (unless there is a global command to disable it)
- mls qos won't work on the 3524 (at least not what I'm running here), I
dont think its new enough to take some of the QoS features.. I always used
switchport trunk extend cos 0 to set the COS of anything hanging off the
phone to 0

I would try using switchport mode access, and then making sure
"spanning-tree portfast" is set on the interface. I dont see it on your
config above so maybe thats causing a problem. i've seen the phones bugger
up while they are waiting for the port to come up if portfast isnt on.
