Re: priority ip phone on switch acces port.

Friend,

A cisco VoIP phone is capable of setting the Precendence bits (COS) in its packets

Actually it sets the DSCP to EF and Cos to 5. The switch overrides these settings by default. You should configure your switch ports to trust the settings sent by the phone

to prioritise traffic for a particular PC, you can configure a Class/ mark the packets sent by the machine and set priority explictly

HTH, rate if it does
