ePDG Thresholds

EPDG Thresholds

Thresholds generate alerts or alarms based on either the total number of ePDG calls setup by the system during the specified polling interval, or on the number of currently active calls only.

Alerts or alarms are triggered for call setups based on the following rules:

  • Enter condition: Actual number of call setups > or = High Threshold

  • Clear condition: Actual number of call setups < Low Threshold

If a trigger condition occurs within the polling interval, the alert or alarm will not be generated until the end of the polling interval.

Default ePDG threshold polling interval value is 5 Min.

The polling interval is in seconds and it is an integer between 30 and 60000. Entries will be rounded up to the nearest 30 seconds.

Configuring ePDG Thresholds

Use the following configuration example to enable, disable and configure ePDG threshold monitoring. 

configure  
      [ no  ] threshold monitoring epdg-service  
 threshold   epdg-current-sessions  current_epdg_sessions_threshold clear  alarm_clear_threshold 
 default  threshold   epdg-current-sessions  
 threshold  poll  epdg-current-sessions  interval  threshold_polling_interval 
 default  threshold  poll  epdg-current-sessions  interval  
      end

Saving Your Configuration

When you configure thresholds they are not permanent unless you save the changes. When you have completed configuring thresholds, save your configuration to flash memory, an external memory device, and/or a network location using the Exec mode command save configuration . For additional information on how to verify and save configuration files, refer to the System Administration Guide and the Command Line Interface Reference.

Configuring IKEv2 tunnel setup attempts

Use the following configuration example to enable, disable and configure ePDG threshold monitoring. 

configure  
          context  epdg context 
            epdg-service  epdg_service_name   
             no   threshold ikev2-setup-attempts  threshold_value  clear  clear_value 
          exit  threshold  poll  epdg-current-sessions  interval  
       exit
