QoS for mls qos queue-set output x threshold x In Cisco 3750 switch

[george85]

Hi guys,

for example if I have 2 x different queue id's "qset-id" with each queue has 4 different threshold "queue-id".

Also exists configuration for buffers.

mls qos queue-set output 1 threshold 1 xx xx xx xx
mls qos queue-set output 1 threshold 2 xx xx xx xx
mls qos queue-set output 1 threshold 3 xx xx xx xx
mls qos queue-set output 1 threshold 4 xx xx xx xx
mls qos queue-set output 2 threshold 1 xx xx xx xx
mls qos queue-set output 2 threshold 2 xx xx xx xx
mls qos queue-set output 2 threshold 3 xx xx xx xx
mls qos queue-set output 2 threshold 4 xx xx xx xx
mls qos queue-set output 1 buffers 15 30 10 45
mls qos queue-set output 2 buffers 15 35 10 40

My question is. that if all the above configuration to take place, i must apply it in the interface?

Switch(config)# interface gigabitethernet2/0/1

Switch(config-if)# queue-set 2

If the queue-set "1 or 2" command didn't exists, the configuration for QoS that write in global config will not be enable for output traffic?

thanks

George

Queue-set 1 is the implicit default for interfaces. You only need to configure queue-set 2 to override the default on an interface.
