Disabling Idle-Client Probing; Changing The User Idle Timeout - D-Link DWS-1008 - AirPremier MobileLAN Switch Product Manual

By default, an AP radio sends keepalive messages (idle-client probes) every 10 seconds to each client
that has an active session on the radio, to verify that the client is still active. The probes are unicast null-
data frames. Normally, a client that is still active sends an Ack in reply to an idle-client probe.
If a client does not send any data or respond to any idle-client probes before the user idle timeout
expires, MSS changes the client's session to the Disassociated state.
Responding to keepalive messages requires power use by a client. If you need to conserve power on
the client (for example, on a VoIP handset), you can disable idle-client probing.
To disable or reenable idle-client probing, use the following command:
set service-profile name idle-client-probing {enable | disable}
The following command disables idle-client probing on service profile sp1:
DWS-1008# set service-profile sp1 idle-client-probing disable
success: change accepted.
The user idle timeout specifies the number of seconds a client can remain idle before the switch changes
the client's session to the Disassociated state. A client is considered to be idle if it does not send data
and does not respond to idle-client probes. You can specify a timeout value from 20 to 86400 seconds.
The default is 180 seconds (3 minutes). To disable the user-idle timeout, set it to 0.
To change the user-idle timeout, use the following command:
set service-profile name user-idle-timeout seconds
The following command increases the user idle timeout to 360 seconds (6 minutes):
DWS-1008# set service-profile sp1 user-idle-timeout 360
success: change accepted.
