auto qos voip Chapter 2 Catalyst 3560 Switch Cisco IOS Commands 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.

Defines the default CoS value of a port or assigns the default CoS to all incoming packets on the port. Defines the CoS-to-DSCP map or the DSCP-to-CoS map. Allocates buffers to a queue-set. Assigns shaped round robin (SRR) weights to an ingress queue. Allocates the buffers between the ingress queues. Maps CoS values to an ingress queue or maps CoS values to a queue and to a threshold ID. Maps DSCP values to an ingress queue or maps DSCP values to a queue and to a threshold ID. Configures the ingress priority queue and guarantees bandwidth. Maps CoS values to an egress queue or maps CoS values to a queue and to a threshold ID. Maps DSCP values to an egress queue or maps DSCP values to a queue and to a threshold ID. Configures the port trust state. Maps a port to a queue-set. Displays auto-QoS information. Displays QoS information at the port level. 2-20 Catalyst 3560 Switch Command Reference 78-16405-05
