Description Automatically Generated Command {voip}
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 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.
Note Catalyst 2960-S switches do not support
ingress queueing.
Switch(config)# no mls qos srr-queue input cos-map
Switch(config)# mls qos srr-queue input cos-map queue 1
threshold 2 1
Switch(config)# mls qos srr-queue input cos-map queue 1
threshold 3 0
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.
Note Catalyst 2960-S switches do not support
ingress queueing.
