The forwarding mode for class 6 (voice)
is strict. The SmartPath AP forwards
packets belonging to this class
immediately without queuing them.
2. Create a user profile and apply the QoS policy to it.
user-profile employee-net qos-policy voice attribute 2
You apply the QoS policy "voice" to all users belonging to the user-profile "employee-net" with attribute 2. On the RADIUS
server, you must configure Attribute 2 as one of the RADIUS attributes that the RADIUS server returns when authenticating users
(see Step 5 on the next page).
NOTE: When SmartPath AP-1 does not use RADIUS for user authentication, you must assign the user profile to an SSID. To do
that, use the following command: ssid employee default-user-profile-attr 2
save config
exit
Step 4: Configure SmartPath AP-2 and SmartPath AP-3.
1. Log in to SmartPath AP-2 through its console port.
2. Configure SmartPath AP-2 with the same commands that you used for SmartPath AP-1:

The user profile rate defines the total amount of bandwidth for all users to which
this policy applies. The user rate defines the maximum amount for any single
user. The user rate can be equal to but not greater than the user profile rate.
(Note: The maximums shown here are for SmartPath APs that support 802.11n
data rates. For other SmartPath APs, the maximum rates are 54,000 Kbps.)

The forwarding mode for class 5 (streaming media) and 2 - 3
(data) is WRR (weighted round robin). The SmartPath AP
forwards traffic belonging to these classes by putting them into
forwarding queues. The weights determine how many bits per
second go into each queue. For every 30 bits that the
SmartPath AP queues for class 2, it queues approximately
60 bits for class 3, and 90 bits for class 5. These amounts are
approximations because the SmartPath AP also has an internal
set weights for traffic in different classes that skews forwarding
in favor of traffic belonging to higher classes.
