Load-balancing methods
The AC supports AP-based load balancing and group-based load balancing.
1. AP-based load balancing
AP-based load balancing can be either implemented among APs or among the radios of an AP.
AP-based load balancing—APs can carry out either session-mode or traffic-mode load
balancing as configured. An AP starts load balancing when the maximum threshold and gap
are reached, and does not accept any association requests unless the load decreases below
the maximum threshold or the gap is less than the maximum gap. However, if a client has been
denied more than the specified maximum times, the AP considers that the client is unable to
associate to any other AP and accepts the association request from the client.
Radio-based load balancing—The radios of an AP that is balanced can carry out either
session-mode or traffic-mode load balancing as configured. A radio starts load balancing
when the maximum threshold and gap are reached and will reject any association requests
unless the load decreases below the maximum threshold or the gap is less than the maximum
gap. However, if a client has been denied more than the specified maximum times, the AP
considers that the client is unable to associate to any other AP and accepts the association
request from the client.
2. Group-based load balancing
To balance loads among the radios of different APs, you can add them to the same load balancing
group.
The radios in a load balancing group can carry out either session-mode or traffic-mode load
balancing as configured. The radios that are not added to any load balancing group do not carry
out load balancing. A radio in a load balancing group starts load balancing when the maximum
threshold and gap are reached on it, and the radio does not accept any association requests
unless the load decreases below the maximum threshold or the gap is less than the maximum gap.
However, if a client has been denied more than the specified maximum times, the AP considers
that the client is unable to associate to any other AP and accepts the association request from the
client.
AP version setting
A fit AP is a zero-configuration device. It can automatically discover an AC after power-on. To make sure
a fit AP can associate with an AC, their software versions must be consistent by default, which
complicates maintenance. This task allows you to designate the software version of an AP on the AC, so
that they can associate with each other even if their software versions are inconsistent.
Switching to fat AP
You can switch the working mode of an AP between the fit mode and the fat mode.
Wireless location
Wireless location is a technology to locate, track and monitor specified devices by using WiFi-based
Radio Frequency Identification (RFID) and sensors. With this function enabled, APs send Tag or MU
messages to an AeroScout Engine (referred to as AE hereinafter), which performs location calculation
and then sends the data to the graphics software. You can get the location information of the assets by
maps, forms, or reports. Meanwhile, the graphics software provides the search, alert and query functions
to facilitate your operations.
