Enabling AutoQoS on Catalyst Switches

You can use one single command to enable QoS on your catalyst switches, and QoS will be applied to the switchports automatically.

Catalyst (config-if) # auto qos voip cisco-phone

It can achieve the following with AutoQoS macro:

• Enforces a trust boundary at Cisco IP Phones
• Enforces a trust boundary on Catalyst switch access ports and uplinks/downlinks
• Enables Catalyst strict priority queuing for voice and weighted round robin queuing for data traffic
• Modifies queue admission criteria (i.e. CoS to-queue mapping)
• Modifies queue sizes, as well as queue weights where required
• Modifies CoS-to-DSCP and IP precedence to-DSCP mappings
