Viewing and Configuring Wireless Services 265 Static CoS—When enabled, marks all traffic on the SSID with thesame CoS value (the Static CoS Value). This option is automaticallyenabled for Vocera voice service profiles but is disabled for all otherservice profile types. Static CoS Value—CoS value assigned by the MAP to all traffic on theSSID of the service profile, when static CoS is enabled. This value isused only when static CoS is enabled. The default is 0 if you enablestatic CoS manually. However, if static CoS is enabled automatically aspart of a Vocera service profile, the default is 7 (highest priority). CAC Mode—Call Admission Control (CAC) policy for allowing newsessions on the radios serving an SSID: None—CAC is disabled. This is the setting automatically selectedfor all service profile types except Vocera voice service profiles. Sessions—CAC is session-based. A MAP radio cannot have morethan the specified number of active sessions for the SSID. This isthe setting automatically selected for Vocera voice service profiles. Max Sessions—When the CAC mode is Sessions, it specifies themaximum number of active sessions radios can have for the SSID. Thedefault is 12. Short Retry Count—Number of times (1 to 15) the MAP transmits anunacknowledged unicast frame that is shorter than the fragmentthreshold before discarding the frame. The default is 5. Long Retry Count—Number of times (1 to 15) the MAP transmits anunacknowledged unicast frame that is equal to or longer than thefragment threshold before discarding the frame. The default is 5.Client Timeout TabThe Client Timeout tab lists settings for client session timers: User idle timeout—Number of seconds a client can remain idle beforethe client’s session is changed to the Disassociated state. A client isconsidered to be idle until it either sends data or responds to an idleclient probe. You can specify from 20 to 86400 seconds. The default is180 seconds (3 minutes.) To disable the timer, specify 0. Idle client probing—When enabled, sends a keepalive probe (a nulldata frame) to each wireless client. The frame is sent as a unicast. TheWX expects a reply in the form of an Ack. Idle client probing isenabled by default.
