Chapter 34 Configuring QoS
Configuring Auto-QoS
The switch automatically maps DSCP values to an egress
queue and to a threshold ID.
Switch(config)# no mls qos srr-queue output dscp-map
Switch(config)# mls qos srr-queue output dscp-map
queue 1 threshold 3 40 41 42 43 44 45 46 47
Switch(config)# mls qos srr-queue output dscp-map

queue 4 threshold 3 0 1 2 3 4 5 6 7
The switch automatically sets up the ingress queues, with
queue 2 as the priority queue and queue 1 in shared mode. The
switch also configures the bandwidth and buffer size for the
ingress queues.
Switch(config)# no mls qos srr-queue input
priority-queue 1
Switch(config)# no mls qos srr-queue input
priority-queue 2
Switch(config)# mls qos srr-queue input bandwidth 90
10
Switch(config)# mls qos srr-queue input threshold 1
8 16
Switch(config)# mls qos srr-queue input threshold 2
34 66
Switch(config)# mls qos srr-queue input buffers 67
33
The switch automatically configures the egress queue buffer
sizes. It configures the bandwidth and the SRR mode (shaped
or shared) on the egress queues mapped to the port.
Switch(config)# mls qos queue-set output 1 threshold
1 138 138 92 138
Switch(config)# mls qos queue-set output 1 threshold
