Configuring Classification Using Port Trust States; Configuring The Trust State On Ports Within The Qos Domain - Cisco 3750G - Catalyst Integrated Wireless LAN Controller Configuration Manual

Configuring Standard QoS
Beginning in privileged EXEC mode, follow these steps to enable VLAN-based QoS. This procedure is
required on physical ports that are specified in the interface level of a hierarchical policy map on an SVI.
Command
Step 1
configure terminal
Step 2 interface interface-id
Step 3 mls qos vlan-based
Step 4 end
Step 5
show mls qos interface interface-id
Step 6 copy running-config startup-config
Use the no mls qos vlan-based interface configuration command to disable VLAN-based QoS on the
physical port.

Configuring Classification Using Port Trust States

These sections describe how to classify incoming traffic by using port trust states. Depending on your
network configuration, you must perform one or more of these tasks or one or more of the tasks in the
"Configuring a QoS Policy" section on page

Configuring the Trust State on Ports within the QoS Domain

Packets entering a QoS domain are classified at the edge of the QoS domain. When the packets are
classified at the edge, the switch port within the QoS domain can be configured to one of the trusted
states because there is no need to classify the packets at every switch within the QoS domain.

Purpose
Enter global configuration mode.
Specify the physical port, and enter interface configuration
mode.
Enable VLAN-based QoS on the port.
Return to privileged EXEC mode.
Verify if VLAN-based QoS is enabled on the physical port.
(Optional) Save your entries in the configuration file.
