Create Overload Profile

The overload profile determines the various conditions for overload control and throttling decisions.

To create the overload profile, use the following sample configuration:

config 
   profile overload overload_profile_name 
      overload-exclude-profile self-protection overload_exclude_profile_name 
      node-level 
         tolerance minimum min_percentage maximum max_percentage 
         reduction-metric minimum min_percentage maximum max_percentage 
         advertise [ interval oci_broadcast_interval | change-factor oci_change_factor | validity-period oci_validity_period ] 
         interface gtpc overloaded-action advertise 
      peer-level 
         message-prioritization group1 weight group2 weight 
         interface gtpc  
            action throttle 
         end 

NOTES:

  • profile overload overload_profile_name : Specify the overload profile name. overload_profile_name must be an alphanumeric string.

    Important

    You can configure only one overload profile with this command. Create exclude profile before configuring overload profile.

  • overload-exclude-profile self-protection overload_exclude_profile_name : Specify the exclude profile name that is configured for use during overload self-protection mode.

    overload_exclude_profile_name must be an alphanumeric string.

  • node-level : Specify to apply the configuration only for the overloaded SMF node.

  • tolerance minimum min_percentage maximum max_percentage : Specify the minimum and maximum percentage of the system load tolerance. min_percentage and max_percentage must be an integer in the range of 1-100.

    min_percentage : This value is the tolerance level below which the system is considered to be in Normal state. Default value is 80.

    max_percentage : This value is the tolerance level above which the system is considered to be in Self-protection state. Default value is 95.

    If the value is between the configured minimum and maximum tolerance values, then the system is in Overloaded state.

  • reduction-metric minimum min_percentage maximum max_percentage : Specify the minimum and maximum percentage of the traffic reduction factor. min_percentage and max_percentage must be an integer in the range of 1-100.

    min_percentage : This value is the percentage of traffic reduction in tandem with minimum tolerance configuration. Default value is 10.

    max_percentage : This value is the percentage of traffic reduction in tandem with maximum tolerance configuration . Default value is 100.

  • advertise interval oci_broadcast_interval : Specify the periodic interval for sending OCI to the GTP-C peers.

    oci_broadcast_interval must be an integer in the range of 0-3600. Value 0 indicates that the OCI is sent in all the messages. Default value is 300 seconds.

  • advertise change-factor lci_change_factor : Specify the minimum change between current OCI and last indicated OCI, after which the OCI advertising occurs.

    oci_change_factor must be an integer in the range of 1-20. Default value is 5.

  • advertise validity-period oci_validity_period : Specify the validity period of the advertised OCI value.

    oci_validity_period must be an integer in the range of 1-3600. Default value is 600 seconds.

  • interface gtpc overloaded-action advertise : Specify to enable OCI publish or broadcast on GTP-C interface when the node is overloaded. By default, this option is disabled.

  • peer-level : Specify to apply the configuration only for the overloaded peer.

  • message-prioritization group1 weight group2 weight : Specify the ratio in which the messages need to be throttled for both the message groups. Each group contains a predefined set of messages from every SMF interface.

    weight must be an integer in the range of 1-100. The default value is 50.

  • interface gtpc action throttle : Enables the throttling action over S6, S8, and S2b interfaces.
