„
Long Retry Count—Number of times (1 to 15) the MAP transmits an 
unacknowledged unicast frame that is equal to or longer than the 
fragment threshold before discarding the frame. The default is 5.
Client Timeout Tab
The Client Timeout tab lists settings for client session timers:
„
User idle timeout—Number of seconds a client can remain idle before 
the client’s session is changed to the Disassociated state. A client is 
considered to be idle until it either sends data or responds to an idle 
client probe. You can specify from 20 to 86400 seconds. The default 
is 180 seconds (3 minutes.) To disable the timer, specify 0. 
„
Idle client probing—When enabled, sends a keepalive probe (a null 
data frame) to each wireless client. The frame is sent as a unicast. The 
WX expects a reply in the form of an Ack. Idle client probing is 
enabled by default. 
„
Web-portal session timeout—Specifies how many seconds MSS waits 
after a Web-Portal client enters the Disassociated state before 
terminating the client’s session. This can be useful if you want to allow 
a client connecting through Web Portal WebAAA to enter standby or 
hibernation mode, then be able to resume its session after waking up, 
without having to log in again. You can specify from 5 seconds up to 
2800 seconds (a little over 46 minutes). The default is 5 seconds. The 
timeout change applies globally for all Web-Portal sessions on the 
service profile’s SSID. This option applies only to Web-Portal service 
profiles. 
Rate Configuration Tab
The Rate Configuration tab lists the data rates supported and used by 
MAP radios. For each radio type (802.11a, 802.11b, and 802.11g), the 
following rates are individually configurable:
„
Beacon rate—Data rate at which the radio sends beacon (SSID 
advertisement) frames and probe-response frames. The valid rates 
depend on the radio type and are the same as the mandatory rates. 
However, you cannot set the beacon rate to a disabled rate. The 
default depends on the radio type:
„
802.11a—6.0
„
802.11b—2.0
„
802.11g—2.0
