Field Description
Disassociation
Timeout
Enter the amount of time (in seconds) a wireless device can
remain inactive (no data sent to or from the wireless device)
before automatically disconnecting from the network.
DTIM Period The period of time after which broadcast and multicast packets are
transmitted to mobile clients in the Active Power Management
mode.
Select the DTIM period for the selected ESSID. This is relevant
for clients that want to utilize the power management capability.
The possible values are 1-5. The default is 3.

Beacon Rate Control
The EXSW creates a hearing relationship table between APs. It forms an AP Bundles group
(Bundle of APs – group of APs, each bundle can include 1 or more APs). The total number of
bundles is equal to the number of APs. Each bundle can send a Beacon at the same time interval.
Then a transmission occurs based on round-robin between bundles (every 100msec). In order to
compensate sensitive clients for a lost beacon, it is possible to set (per SSID) the Beacon rate
control at a higher threshold. Although the feature minimizes the possibility of clients receiving
duplicate beacons, there is no guarantee of zero duplicate/missed beacons.
* Clients near AP1 hear only 1 beacon out of 5, therefore Hearing % is 20%.
