When I connect my Cisco IP Phone 7960 with 2950 Switch (any access port within voice vlan), I get the message on Port duplex mismatch but the phone works properly.
From my switch the speed setting is 100/Full but from the Phone its Auto.
My Question is when I try to change duplex settings from Phone, it doesn't gives me any option instead only one option available to save so kindly someone tell me the best way to fix this from Phone or do I have to change the duplex from switch to AUTO ?

Hi,
You should always set your swicthport to be AUTO speed & AUTO duplex when connecting to ip phones
!
int fas 0/XX
speed auto
duplex auto
!
Try that and see what happens

Hi,
That looks like you have the wrong speed/parity on your console,
The defaults are 9600 -8N1

Problem solved, that was the console cable issue.
