1. When the total traffic rate from the AP to all clients is lower than 10000 kbps, the rate of traffic
from the AP to any client is not limited.
2. Suppose the rate of traffic from the AP to Client 1 exceeds 2000 kbps and the rate of traffic from
the AP to Client 2 exceeds 8000 kbps, and the rate of traffic from the AP to all clients exceeds
10000 kbps. In this case, because WLAN services research and office are configured with
bandwidth guaranteeing, the AP will preferentially forward traffic from the AP to Client 1 and
Client 2. As a result, the AP sends traffic to Client 1 at a rate of 2000 kbps, the AP sends traffic to
client 2 at a rate of 8000 kbps, and the rate of traffic from the AP to Client 3 is limited.
Configuring client 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. 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 limit of each client is 2 Mbps.
• Configure the maximum bandwidth that can be used by each client. This is called "static mode". For
example, if the configured rate is 1 Mbps, the rate limit of each client 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.
Configuration procedure
You can configure WLAN service-based client rate limiting, so that the AC can limit client rates for a
WLAN service.
To configure WLAN service-based client rate limiting:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter service template view.

Disabled by default.
You can configure radio-based client rate limiting, so that the AC can limit client rates for the same radio.
To configure radio-based client rate limiting (available only on ACs):
