Threshold-limits

Aruba Employee

Question:         How to check the controller's current threshold values?


Environment:         1) How to find the controller fan-speed
                                 2) While troubleshooting packet loss and datapath issue
                                 3) Client connectivity issue due to user-capacity reached.


Answer :        By using below commands we can check the controllers current running value and threshold value.   

show threshold-limits controlpath-memory|fan-speed|no-of-aps|no-of-locals|total-tunnel-capacity|user-capacity

This command shows current values of the different resources monitored by the controller.

controlpath-memory: The output of this command displays the default memory threshold which, when exceeded, will trigger an alert, the current configured threshold, the total memory
(in MB) and the currently available memory (in MB).

fan-speed: The output of this command displays the fan alert threshold. This parameter is only available for controllers with fans, such as the M3 and 7200 series.

no-of-ap:  The output of this command displays the following values:

 
  • The default threshold for the number of APs, which, when exceeded, will trigger an alert
  • The current configured threshold.
  • The maximum number of APs supported by the controller,
  • The number of available licenses for campus and remote APs,
  • The total number of APs, and the current number of campus, remote and virtual APs.

no-of-locals: The output of this command displays the default threshold for the number of local controllers which, when exceeded, will trigger an alert, and the current configured

threshold. The output also displays the maximum number of local controllers that can be connected to this master controller, and the number of local controllers currently connected.

total-tunnel-capacity: The output of this command displays the default tunnel capacity threshold which, when exceeded, will trigger an alert, as well as the current configured tunnel
threshold. The output also includes the maximum number of tunnels supported by the controller, as well as the number of tunnels currently used by the controller.

user-capacity: The output of this command displays the default user capacity threshold which, when exceeded, will trigger an alert, as well as the current configured user
threshold. The output also includes the maximum number of users supported by the controller, as well as the number of users currently associated with the controller.

The controller will send a wlsxThresholdAbove SNMP trap and a syslog error message when the controller has exceeded a set percentage of the total capacity for that resource. A wlsxThresholdBelow SNMP trap and error message will be triggered if the resource usage drops below the threshold once again.

Sample Output:

no-of-aps                Display current no of APs (CAP,RAP,VAP, Total APs)
                        connected to the system.
no-of-locals             Display no of locals connected to this master.
total-tunnel-capacity    Display threshold info of  total number tunnels .
user-capacity            Display current no of users in the  system.
