Configuring Auto-QoS
When you enable auto-QoS by using the auto qos voip cisco-phone, the auto qos voip cisco-softphone,
or the auto qos voip trust interface configuration command, the switch automatically generates a QoS
configuration based on the traffic type and ingress packet label and applies the commands listed in
Table 32-5 to the port.
Ta b l e 32-5 Generated Auto-QoS Configuration
Description Automatically Generated Command
The switch automatically enables standard QoS and configures
the CoS-to-DSCP map (maps CoS values in incoming packets
to a DSCP value).
Switch(config)# mls qos
Switch(config)# mls qos map cos-dscp 0 8 16 26 32 46
48 56
The switch automatically maps CoS values to an ingress queue
and to a threshold ID.
Switch(config)# no mls qos srr-queue input cos-map
Switch(config)# mls qos srr-queue input cos-map
queue 1 threshold 3 0
Switch(config)# mls qos srr-queue input cos-map
queue 1 threshold 2 1
Switch(config)# mls qos srr-queue input cos-map
queue 2 threshold 1 2
Switch(config)# mls qos srr-queue input cos-map
queue 2 threshold 2 4 6 7
Switch(config)# mls qos srr-queue input cos-map
queue 2 threshold 3 3 5
The switch automatically maps CoS values to an egress queue
and to a threshold ID.
Switch(config)# no mls qos srr-queue output cos-map
Switch(config)# mls qos srr-queue output cos-map
queue 1 threshold 3 5
Switch(config)# mls qos srr-queue output cos-map
queue 2 threshold 3 3 6 7
Switch(config)# mls qos srr-queue output cos-map
queue 3 threshold 3 2 4
Switch(config)# mls qos srr-queue output cos-map
queue 4 threshold 2 1
Switch(config)# mls qos srr-queue output cos-map
queue 4 threshold 3 0
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
