Hello
To allocate the bandwidth, use this command:
(config-if)# srr-queue bandwidth shape 0 0 0 0 (this disables shape mode)
(config-if)# srr-queue bandwidth share 10 20 30 40
Check 3560 QoS configuration Guide to see default settings, which queue CoS
and DSCP values belong to.
Then for example move cos 1 to Q3:
(config)# mls qos srr-queue output cos-map queue 3 1 2 3
HTH,
Phuc
