Configuring Overload Control for Voice Calls

You configure overload control by configuring the queue limit percentage, the threshold for rejecting non-emergency new calls, and the threshold for rejecting all non-emergency transactions except for SUBTRACT transactions. When you configure overload control for the BGF, you must set the reject-new-calls-threshold to a value greater than or equal to the queue-limit-percentage, and you must set the reject-all-commands-threshold to a value greater than or equal to the reject-new-calls-threshold.

To configure overload-control for voice calls:

  1. Access the configuration of overload control.
    [edit services pgcp gateway bgf-1]user@host# edit overload-control
  2. Configure a queue limit percentage.
    [edit services pgcp gateway bgf-1 overload-control]user@host# set queue-limit-percentage 70
  3. Configure a threshold for rejecting all non-emergency new calls.
    [edit services pgcp gateway bgf-1 overload-control]user@host# set reject-new-calls-threshold 80
  4. Configure a threshold for rejecting all non-emergency new transactions except SUBTRACT transactions.
    [edit services pgcp gateway bgf-1 overload-control]user@host# set reject-all-commands-threshold 90

Note: Only one work queue exists for the entire device. The queue limit percentage that you configure applies to the entire device, not just the virtual BGF named in the hierarchy level you have chosen. If you enter multiple queue limit percentages for different virtual BGFs, only the last entry is used.
