Hi everybody.

Does " auto qos voip" require that " mlsqos" be configured first i.e  Switch(config)# mls qos ?

thanks and have a great weekend.

Hi Sarah,

the command auto qos voip will enable qos globaly for you see below:

AutoQoS supports Cisco IP phones with the auto qos voip cisco-phone interface configuration command. When you enter the auto qos voip cisco-phone interface   configuration command on a port that is configured to support an IP   phone and to which an IP phone is connected, the autoQoS feature does   the following:

If QoS was not already enabled, enables QoS globally.

If   VLAN-based QoS was configured for the port, reverts to the default   port-based QoS (done for all ports on switching modules with 1p1q0t/1p3q1t ports).

Sets the port trust state to trust CoS.

Creates and applies a trust-CoS QoS policy to ports on switching modules with non-Gigabit Ethernet 1q4t/2q2t ports, which do not support port trust.
