Table 79: Generated Auto-QoS Configuration for VoIP Devices
Automatically Generated Command (VoIP)Description
Switch(config)# mls qos
Switch(config)# mls qos map cos-dscp 0 8 16 26 32
46 48 56
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)# 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
CoS 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 2
threshold 3 24 25 26 27 28 29 30 31
Switch(config)# mls qos srr-queue output dscp-map queue 2

Switch(config)# mls qos srr-queue output dscp-map queue 2
threshold 3 56 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 32 33 34 35 36 37 38 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 maps
DSCP values to an egress
queue and to a threshold ID.
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.
