Setting rate limiting
The WLAN provides limited bandwidth for each AP. Because the bandwidth is shared by wireless clients
attached to the AP, aggressive use of bandwidth by a client will affect other clients. To ensure fair use of
bandwidth, rate limit traffic of clients in either of the following approaches:
• Configure the total bandwidth shared by all clients in the same BSS. This is called "dynamic mode".
The rate limit of a client is the configured total rate/the number of online clients. For example, if the
configure total rate is 10 Mbps and five clients are online, the rate of each client is 2 Mbps.
• Configure the maximum bandwidth that can be used by each client in the BSS. This is called "static
mode". For example, if the configured rate is 1 Mbps, the rate limit of each user online is 1 Mbps.
When the set rate limit multiplied by the number of access clients exceeds the available bandwidth
provided by the AP, no clients can get the guaranteed bandwidth.
Setting wireless service-based client rate limiting
You can configure the access controller to limit client rates for a service within a BSS.
To set wireless service-based client rate limiting:
1. Select QoS > Wireless QoS from the navigation tree on the left.
2. Click the Client Rate Limit tab.
3. Click Add in the Service-Based Configuration area to enter the page for setting wireless
service-based client rate limits, as shown in
Figure 573 .

4. Configure service-based client rate limiting, as described in Table 188 .
5. Click Apply.
