• To view detailed client information on the primary and backup ACs, select Summary > Client from
the navigation tree, click the Detailed Information tab, and select the target client. In the command
output, if the client information, except the state (Running for the primary AC, Running(Backup) for
the backup AC), is consistent on the two ACs, the basic client information has been synchronized.
• To view roam-track information of the clients on the primary and backup ACs, select Summary >
Client from the navigation tree, click the Roam Information tab, and select the target client. In the
command output, if the client information is consistent on the two ACs, the basic client information
has been synchronized.
Continuous transmitting mode
The continuous transmitting mode is used for testing only. Do not use the function unless necessary.
Channel busy test
The channel busy test is a tool to test how busy a channel is. It tests channels supported by the
country/region code individually, and provides a busy rate for each channel. This avoids the situation in
which some channels are heavily loaded and some are idle.
During a channel busy test, APs do not provide any WLAN services. All the connected clients are
disconnected, and WLAN packets are discarded.
WLAN load balancing
WLAN load balancing dynamically adjusts loads among APs to ensure adequate bandwidth for clients.
It is mainly used in high-density WLAN networks.
Requirement of WLAN load-balancing implementation
As shown in Figure 467 , Client 6 wants to associate with AP 3. AP 3 has reached its maximum load, so
it rejects the association request. Then, Client 6 tries to associate with AP 1 or AP 2, but it cannot receive
signals from these two APs, so it has to resend an association request to AP 3.
To implement load-balancing, the APs must be managed by the same AC, and the clients can find the
APs.
