Hi Group,

During cos classification of packet when entering FastEthernet port on
Catalyst 3550 switch, do I need to trust the cos value before
performing cos-mapping ?

i.e.

interface FastEthernet 0/1
 mls qos trust cos <--- Is this needed to performing cos-mapping ?
 wrr-queue cos-map 1 5 6 7
 wrr-queue cos-map 2 2 3 4
 wrr-queue cos-map 3 1
 wrr-queue cos-map 4 0

Thanks !
Ryan
