To configure this feature, use the following configuration:

config 
   profile wps wps_name 
      arp arp_value 
      dscp dscp_value 
      message-priority [ pfcp | gtpc ] 
      end 

NOTES:

• wps wps_name —Specify the WPS service name. Must be a string.

• arp arp_value —Specify the range of ARP levels (separated by , or -). Must be an integer or a string.

• dscp dscp_value —Specify the DSCP marking value in the decimal range 0-63 or hex range 0x0-0x3F. Must be a string.

• message-priority —Specify the message priority for GTP-C and UP. Must be one of the following:

  • gtpc

  • pfcp

To configure WPS-Profile and SGW-Profile association, use the following configuration:

config 
 profile sgw sgw_name 
  wps-profile wps_name 
  end 

NOTES:

• wps-profile wps_name —Specify the Wireless Priority Service (WPS) name. Must be a string.

This section describes how to configure WPS-Profile and DNN-Profile association.

Note	If WPS profile is associated with SGW profile and DNN profile, DNN profile takes the priority.

To configure WPS-Profile and DNN-Profile association, use the following configuration:

config 
 profile dnn dnn_name 
   wps-profile wps_name 
   end

To configure the Overload Exclude profile, use the following configuration:

config 
   profile overload-exclude overload_exclude_profile_name 
      dnn-list list_of_dnn  
      arp-list list_of_arp 
      end 

NOTES:

• overload-exclude overload_exclude_profile_name — Specify the exclude overload profile name.

• dnn-list list_of_dnn —Specify the list of DNNs that needs to be excluded from throttling decision. Maximum three entries are allowed.

• arp-list list_of_arp —Specify the ARP list that needs to be excluded from throttling decisions. Must be an integer in the range of 1-15. Maximum eight entries are allowed.

The association of the Overload-Profile and the SGW-Profile, can be configured.

To configure this feature use the following configuration:

config 
    profile overload overload_profile_name 
        overload-exclude-profile self-protection self_protection_profile_name 
    node-level 
        tolerance 
            minimum min_percentage 
            maximum max_percentage 
        reduction-metric 
            minimum min_percentage 
            maximum max_percentage 
            advertise 
            interval interval_value 
            change-factor 
            exit 
        interface gtpc 
            overloaded-action [ advertise ] 
            exit 
        exit 
    exit 
    profile load load_name 
    load-calc-frequency load_calc_frequency_value

    advertise 
    interval interval_value 
    change-factor change_factor_value 
    exit 
    interface gtpc 
    action advertise 
    exit 
exit 
profile sgw sgw_name
