Re: 3750 Outbound Queues

Hi Joe

Your 2636 count seems to map to Q1T2

Nothing seems like it is mapped to 2/2 by default.

But looking at doc cd you can map dscp/cos to this space
Rack1SW1(config)#mls qos srr-queue output dscp-map queue 2 threshold 2 24 26
Rack1SW1(config)#mls qos srr-queue output cos-map queue 2 threshold 2 3
