auto qos voip
To disable auto-QoS on a port, use the
no auto qos voip
interface configuration command. Only the
auto-QoS-generated interface configuration commands for this port are removed. If this is the last port
on which auto-QoS is enabled and you enter the
no auto qos voip
command, auto-QoS is considered
disabled even though the auto-QoS-generated global configuration commands remain (to avoid
disrupting traffic on other ports affected by the global configuration). You can use the
no mls qos
global
configuration command to disable the auto-QoS-generated global configuration commands. With QoS
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 gigabitethernet0/1
Switch(config-if)#
auto qos voip trust
You can verify your settings by entering the
show auto qos interface
interface-id
privileged EXEC
command.
