This window lets you configure the quality of service (QoS) on your access point. With this feature, you can provide preferential treatment to certain traffic. Without QoS, the access point offers best-effort service to each packet, regardless of the packet contents or size. It sends the packets without any assurance of reliability, delay bounds, or throughput.

Create/Edit Policies

Create/Edit Policy

If you are entering a new policy, make sure <NEW> (the default) is selected in the Create/Edit Policy menu. To edit an existing policy, select the policy name from the Create/Edit Policy menu.

Policy Name

Enter a policy name to attach to an input or output interface.

Classifications

Classification is the process of distinguishing one kind of traffic from another by examining the fields in the packet. Specify the fields in the frame or packet you want to use to classify incoming traffic.

Match Classifications

All switches and routers that access the Internet rely on the class information to provide the same forwarding treatment to packets with the same class information and different treatment to packets with different class information.

IP Precedence

Eight IP precedence values are defined in RFC791. Select any of them as matching criteria.

IP DSCP

IP DSCP (Differentiated Service Code Point) is defined in RFC2474. Select IP DSCP values as matching criteria.

IP Protocol 119

This protocol is for matching the SpectraLink Voice Protocol.

Filter

If you have filters set up, you can assign a priority to packets that match the selected filter. In the Filter drop-down menu, select which filter you want to include in the policy. For example, you could assign a high priority to a MAC address filter that includes the MAC addresses of IP phones.

Note: The access list you use in QoS does not affect the access point's packet forwarding decisions.

Apply Class of Service

Determine the class of service that the access point will apply to packets that match the filter that you selected from the Filter menu. Click the Add button beside the Class of Service drop-down.

Apply Policies to Interface/VLANs

After QoS policies are created and applied, you can assign the policies to ingoing or outgoing traffic of any of the two interfaces.

Incoming

Use the drop-down menu to choose which policy you want to assign for FastEthernet and 802.11 radio interfaces.

Outgoing

Use the drop-down menu to choose which policy you want to assign for FastEthernet and 802.11 radio interfaces.
