Load Balancing
Max Client: The maximum number of clients the that can connect to this prole.
RSSI: Denes the weakest signal that the APs in this prole will accept.
The controller supports balancing of load on the APs it manages. This is based on the number of clients connected to APs as
well as signal quality of clients. At the time a client discovers APs (using probe requests) or sends association frames, AP de-
cides whether to accept a client or not based on the number of clients already connected or the signal strength of the clients.
The two congurations are:
Max Clients: The maximum number of wireless clients that can connect to each radio of Access Point at one time. A value of 64
can be selected to specify to allow maximum supported by Access Point.
RSSI: The minimum signal quality in percentage (0 - 100) % expected from the wireless clients that connect to the Access
Points. A value of 0 means this check is not enforced and load balancing is disabled.
Setting the Max. number of clients to a low value (compared to the total number of client in an ofce/oor) is recommended
when there are several APs and the administrator would like a good distribution of clients between the access points.
Setting the RSSI to a high percentage would mean that only clients near to APs will be permitted to associate to the APs and
is good in situation where the throughput expectation is high. In scenarios, where the clients can be expected to be far away
(or the number of APs is less), this should be set to a lower value.
Basic and Advanced - Rate Limiting
The Rate Limiting feature can be congured differently for each BSSID in security prole group. Rate limiting is done per BSSID
and is congured as a percentage of available bandwidth. Available bandwidth is determined by the number of errors occurring
during transmission and the amount of time a packet spends in the transmission queue.
The available bandwidth is distributed among the BSSIDs congured on the Access Points as a specied percentage. The per-
centage congured for a BSSID is shared among all the clients connected to it. The total of the percentages distributed among
the BSSIDs can be up to 100%.
Rate Limiting can be disabled by setting the limit to 0%. This can be useful for having BSSIDs for management/administration/
testing.
Rate Limit: The slider bar and value specify congured rate limit values.
