Configuring APs 249
Nortel WLAN—Security Switch 2300 Series Configuration Guide
The following command sets a 802.11g mandatory rate for service profile sp1 to 54 Mbps and disables rates
1.0 Mbps and 2.0 Mbps:
WSS# set service-profile sp1 transmit-rates 11g mandatory 54.0 disabled 1.0,2.0
The following command maps radio profile rp1 to service profile sp1.
WSS# set radio-profile rp1 service-profile sp1
After these commands are entered, if a client transmitting with a data rate of 1.0 Mbps or 2.0 Mbps attempts to
associate with an AP managed by service profile sp1, that client is not allowed to associate with the AP.
Disabling idle-client probing
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 (see
“Changing the user idle timeout” (page 249)), WSS Software 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:
WSS# set service-profile sp1 idle-client-probing disable
success: change accepted.
Changing the user idle timeout
The user idle timeout specifies the number of seconds a client can remain idle before the WSS 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):
WSS# set service-profile sp1 user-idle-timeout 360
success: change accepted.
