Displaying and Changing Network Session Timers

MSS periodically sends keepalive probes to wireless clients to verify that the clients are still present.
The keepalive probes are null data frames sent as unicasts to each client. MSS expects each client to
respond with an Ack. MSS sends the keepalives every 10 seconds. You can disable the keepalives but
the keepalive interval is not configurable.
MSS also maintains an idle timer for each user (wireless client). Each time the client sends data or
responds to a keepalive probe, MSS resets the idle timer to 0 for the client. However, if the client
remains idle for the period of the idle timer, MSS changes the client's session to the Disassociated state.
The default idle timeout value is 180 seconds (3 minutes). You can change the timeout to a value from
20 to 86400 seconds. To disable the timeout, specify 0.
Keepalive probes and the user idle timeout are configurable on a service-profile basis.
To disable or reenable keepalive probes in a service profile, use the following command:
set service-profile name idle-client-probing {enable | disable}

Changing or Disabling the User Idle Timeout

To change the user idle timeout for a service profile, use the following command:
set service-profile name user-idle-timeout seconds
For example, to change the user idle timeout for service profile sp1 to 6 minutes (360 seconds), use the
following command:
DWS-1008# set service-profile sp1 user-idle-timeout 360
success: change accepted.
To disable the user idle timeout, use the following command:
DWS-1008# set service-profile sp1 user-idle-timeout 0
success: change accepted.
