Chapter 11: Deployment Examples CLI

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.)

show qos policy voice

Policy name=voice; user rate limit=1000000kbps;

User profile rate=1000000kbps; user profile weight=10;

Class=0; mode=wrr; weight=10; limit=1000000kbps;

Class=1; mode=wrr; weight=20; limit=1000000kbps;

Class=2; mode=wrr; weight=30; limit=1000000kbps;

Class=3; mode=wrr; weight=60; limit=1000000kbps;

Class=4; mode=wrr; weight=50; limit=1000000kbps;

Class=5; mode=wrr; weight=90; limit=20000kbps;

Class=6; mode=strict; weight=0; limit=512kbps;

Class=7; mode=strict; weight=0; limit=20000kbps;

The forwarding mode for class 6 (voice)

is strict. The SmartPath AP forwards

packets belonging to this class

immediately without queuing them.

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.

Figure 11-10. QoS policy “voice.”

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:

1 2 ... 171 172 173 174 175 176 177 178 179 180 181 ... 191 192
