config qos average−data−rate silver per−ssid downstream limit

Enter this command in order to define the burst data rate in Kbps for TCP traffic per−SSID:

config qos average−data−rate silver per−ssid downstream limit

3. 

Define the average real−time rate in Kbps for UDP traffic per−SSID:

config qos average−realtime−rate silver per−ssid downstream limit

4. 

Define the peak real−time rate in Kbps for UDP traffic per−SSID:

config qos burst−realtime−rate silver per−ssid downstream limit

5. 

Map this QoS profile in WLAN using this command:

config wlan qos wlan_id silver

6. 

Enable both 802.11 a and 802.11 b radios.

7. 

Check that the above values are configured correctly using these show commands:

show qos silver 

show wlan [wlan−id] 

8. 

Associate two or more clients to the above WLAN. Then, start sending TCP and UDP traffic from
wired to wireless clients using a traffic generator (for example, LAN traffic tool or iPerf) more than
the defined parameters above.

For example, if average−data−rate = 1000 Kbps per SSID and burst data rate = 2000 Kbps per SSID,
then all clients together share the bandwidth. Also, traffic of clients together should not exceed more
than 1000 Kbps average per radio of AP.

9. 

Check client statistics using this show command:

(wlc) show client details [mac−addr]

Client Statistics:

      Number of Data Bytes Received................... 160783

      Number of Realtime Bytes Received................... 160783

      Number of Data Bytes Sent....................... 23436

      Number of Realtime Bytes Sent....................... 23436

10. 

Repeat the test case with other QoS profiles: bronze, gold and platinum.

11. 

This is to configure rate limit per−SSID and per−client on downstream traffic. Throughput is limited
accordingly.

Disable both 802.11a and 802.11b radio using these commands:

config 802.11a disable network

config 802.11b disable network

1. 

Define the average data rate in Kbps for TCP traffic per−SSID and per−client:

config qos average−data−rate silver per−ssid downstream limit 

config qos average−data−rate silver per−client downstream limit

2. 

Define the burst data rate in Kbps for TCP traffic per−SSID and per−client:

config qos average−data−rate silver per−ssid downstream limit 

config qos average−data−rate silver per−client downstream limit

3. 

Define the average real−time rate in Kbps for UDP traffic per−SSID and per−client.

config qos average−realtime−rate silver per−ssid downstream limit  

config qos average−realtime−rate silver per−client downstream limit
