Rate limit applied per−SSID and per−client together on upstream traffic
configuration
This is to verify that when rate−limit is applied per−SSID and per−client on upstream traffic, the 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 rate in Kbps for TCP and UDP traffic per−client and per−SSID:
config qos average−data−rate silver per−client upstream limit                                                                                            
config qos average−data−rate silver per−client upstream limit 
config qos average−realtime−rate silver per−client upstream limit  
config qos burst−realtime−rate silver per−client upstream limit                                                                                                    
config qos average−data−rate silver per−ssid upstream limit                                                                                            
config qos average−data−rate silver per−ssid upstream limit 
config qos average−realtime−rate silver per−ssid upstream limit  
config qos burst−realtime−rate silver per−ssid upstream limit
2. 
Map this QoS profile in WLAN using this command:
config wlan qos wlan_id silver
3. 
Enable both 802.11 a and 802.11 b radios.
4. 
Check that the above values are configured correctly using these show commands:
show qos silver
show wlan [wlan−id]
5. 
Associate two or more STA to the above WLAN. Then, start sending TCP and UDP traffic from
wireless to wired client using a traffic generator (for example, LAN traffic tool) more than the defined
parameters above.
For example, if average−data−rate = 5000 Kbps per SSID and average−data−rate = 1000 Kbps per
client, then each of client is limited to 1000 Kbps. Also, all clients traffic together should not exceed
more than 5000 Kbps average per radio of AP.
6. 
Check client statistics using this show command:
(wlc) show client details [mac−addr]
7. 
Optional :Repeat the test case with other QoS profiles: bronze, gold and platinum.
8. 
Rate limit applied per−SSID supercedes global QoS profile on upstream
traffic configuration
This is to verify rate limit defined on WLAN per−SSID upstream overrides values defined under QoS
profiles.
Configure rate limits for UDP and TCP traffic under QoS profile, for example, Silver.
1. 
Map this QoS profile in WLAN.
2. 
Configure different rate limit values on WLAN using these commands:
config wlan override−rate−limit id average−data−rate  per−ssid upstream limit
config wlan override−rate−limit id burst−data−rate  per−ssid upstream limit
config wlan override−rate−limit id average−realtime−rate  per−ssid upstream limit
config wlan override−rate−limit id burst−realtime−rate  per−ssid upstream limit
3. 
Associate different clients to WLAN, and start sending traffic from wireless to wired side.
4. 
Check if the value configured on WLAN is overriden. Use this show command to validate that the
