I think, the question was taken from the old cat5k world and old lab questions. You can't do that in cat3550 AFAIK.

setting port cos would not gaurantee that port would be able to send data through the backplane earlier than some other port with lower cos or no cos. Advantage is that the packet is preferentially treated in the egress scheduling

I'm not really sure my answer correct or not since there is no docs about this ,
change default CoS for all incoming packets from 0 (default value) to higher value, example:
mls qos cos 5


any comments?

Hello Group,

I have a lab requirement which says:-

Configure the 3550 so that if the backplane of the switch gets overloaded, the ports
in VLAN 3 get serviced before the ports in VLAN 5.


Anyone knows how to achieve this?

H.
