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 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.
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.
