Chapter 26 Configuring QoS
Configuring Auto-QoS
The switch automatically maps DSCP values to an ingress
queue and to a threshold ID.
Switch(config)# no mls qos srr-queue input dscp-map
Switch(config)# mls qos srr-queue input dscp-map
queue 1 threshold 2 9 10 11 12 13 14 15
Switch(config)# mls qos srr-queue input dscp-map
queue 1 threshold 3 0 1 2 3 4 5 6 7
Switch(config)# mls qos srr-queue input dscp-map
queue 1 threshold 3 32
Switch(config)# mls qos srr-queue input dscp-map
queue 2 threshold 1 16 17 18 19 20 21 22 23
Switch(config)# mls qos srr-queue input dscp-map
queue 2 threshold 2 26 33 34 35 36 37 38 39
Switch(config)# mls qos srr-queue input dscp-map
queue 2 threshold 2 48 49 50 51 52 53 54 55
Switch(config)# mls qos srr-queue input dscp-map
queue 2 threshold 2 56 57 58 59 60 61 62 63
Switch(config)# mls qos srr-queue input dscp-map

Switch(config)# mls qos srr-queue input dscp-map
queue 2 threshold 3 41 42 43 44 45 46 47
The switch automatically maps DSCP values to an egress
queue in the queue-set 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 2 threshold 3 24 25 27 28 29 30 31 48
Switch(config)# mls qos srr-queue output dscp-map
queue 2 threshold 3 49 50 51 52 53 54 55 56
Switch(config)# mls qos srr-queue output dscp-map
queue 2 threshold 3 57 58 59 60 61 62 63
Switch(config)# mls qos srr-queue output dscp-map
queue 3 threshold 3 16 17 18 19 20 21 22 23
Switch(config)# mls qos srr-queue output dscp-map
queue 3 threshold 3 26 32 33 34 35 36 37 38
Switch(config)# mls qos srr-queue output dscp-map
queue 3 threshold 3 39
Switch(config)# mls qos srr-queue output dscp-map
queue 4 threshold 1 8
Switch(config)# mls qos srr-queue output dscp-map
queue 4 threshold 2 9 10 11 12 13 14 15
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)# no mls qos srr-queue input buffers
The switch automatically configures the egress queue-set
buffer sizes. It configures the bandwidth and the SRR mode
(shaped or shared).
Switch(config)# mls qos queue-set output 1 buffers
20 20 20 40
Switch(config-if)# srr-queue bandwidth shape 10 0 0
0
Switch(config-if)# srr-queue bandwidth share 10 10
60 20
