    CCVP/CCIP QoS(642-642) Lab – DSCP & CoS

    By admin | May 14, 2009

    You are required to configure the fa0/1, fa0/10 and fa0/11 ports on the Cisco Catalyst 2950 switch according to the following:
    On port fa0/1, trust all incoming DSCP settings.
    On port fa0/11, trust all incoming CoS settings.
    On port fa0/10, trust the incoming CoS setting only if a Cisco IP Phone is connected to the fa0/10 port: otherwise do not trust any CoS or DSCP markings coming in.


    The Answer:
