auto qos voip
disabled, there is no concept of trusted or untrusted ports because the packets are not modified (the CoS,
DSCP, and IP precedence values in the packet are not changed). Traffic is switched in pass-through mode
(packets are switched without any rewrites and classified as best effort without any policing).
Examples This example shows how to enable auto-QoS and to trust the QoS labels received in incoming packets
when the switch or router connected to the port is a trusted device:
Switch(config)# interface gigabitethernet2/0/1
Switch(config-if)# auto qos voip trust
You can verify your settings by entering the show auto qos interface interface-id privileged EXEC
command.
Related Commands Command Description
debug auto qos Enables debugging of the auto-QoS feature.
mls qos cos Defines the default CoS value of a port or assigns the default
CoS to all incoming packets on the port.
mls qos map {cos-dscp dscp1 ... dscp8
| dscp-cos dscp-list to cos}
Defines the CoS-to-DSCP map or the DSCP-to-CoS map.
mls qos queue-set output buffers Allocates buffers to a queue-set.
mls qos srr-queue input bandwidth Assigns shaped round robin (SRR) weights to an ingress
queue.
mls qos srr-queue input buffers Allocates the buffers between the ingress queues.
mls qos srr-queue input cos-map Maps CoS values to an ingress queue or maps CoS values to
a queue and to a threshold ID.
mls qos srr-queue input dscp-map Maps DSCP values to an ingress queue or maps DSCP values
to a queue and to a threshold ID.
mls qos srr-queue input

Configures the ingress priority queue and guarantees
bandwidth.
mls qos srr-queue output cos-map Maps CoS values to an egress queue or maps CoS values to
a queue and to a threshold ID.

show mls qos interface Displays QoS information at the port level.
srr-queue bandwidth shape Assigns the shaped weights and enables bandwidth shaping
on the four egress queues mapped to a port.

on the four egress queues mapped to a port.
