    Configuring Resource Thresholds for 3G and 4G Networks

    You configure a resource threshold profile to ensure that when the bearer load, system load, CPU load, or memory load at the access point name (APN) or system level on the MobileNext Broadband Gateway reaches a specified threshold, only Create Session requests that meet or exceed a designated allocation and retention priority level are granted.

    To configure a resource threshold profile:

    1. Specify a name for the resource threshold.
      [edit unified-edge cos-cac]user@host# edit resource-threshold-profiles resource-threshold-1
    2. Configure the bearer priority level and threshold limits for the number of bearers:
      1. Configure the bearer priority when the number of bearers reaches the lower threshold. The following configuration specifies that when the number of bearers exceeds 60 percent of the allowed limit, only Create Session requests with a priority level equal to or higher the specified ARP values are accepted:
        [edit unified-edge cos-cac resource-threshold-profiles resource-threshold-1 bearers-load low]user@host# set percentage 70 user@host# set gtpv1-arp 3 user@host# set gtpv2-priority-level 10
      2. Configure the bearer priority when the number of bearers reaches the upper threshold. The following configuration specifies that when the number of bearers exceeds 80 percent, only Create Session requests with a priority level equal to or higher than the specified ARP values are accepted:
        [edit unified-edge cos-cac resource-threshold-profiles resource-threshold-1 bearers-load high]user@host# set percentage 85 user@host# set gtpv1-arp 2 user@host# set gtpv2-priority-level 4
    3. Configure the bearer priority and threshold limits for the system load:
      1. Configure a lower limit for the system load.
        [edit unified-edge cos-cac resource-threshold-profiles resource-threshold-1 system-load low]user@host# set percentage 70 user@host# set gtpv1-arp 3 user@host# set gtpv2-priority-level 10
      2. Configure an upper limit for the system load.
        [edit unified-edge cos-cac resource-threshold-profiles resource-threshold-1 system-load high]user@host# set percentage 85 user@host# set gtpv1-arp 2 user@host# set gtpv2-priority-level 4
    4. Configure the bearer priority and threshold limits for the CPU load:
      1. Configure a lower limit for the CPU load.
        [edit unified-edge cos-cac resource-threshold-profiles resource-threshold-1 cpu low]user@host# set percentage 70 user@host# set gtpv1-arp 3 user@host# set gtpv2-priority-level 10
      2. Configure an upper limit for the CPU load.
        [edit unified-edge cos-cac resource-threshold-profiles resource-threshold-1 cpu high]user@host# set percentage 85 user@host# set gtpv1-arp 2 user@host# set gtpv2-priority-level 4
    5. Configure the bearer priority and threshold limits for the memory load:
      1. Configure a lower limit for the memory load.
        [edit unified-edge cos-cac resource-threshold-profiles resource-threshold-1 memory low]user@host# set percentage 70 user@host# set gtpv1-arp 3 user@host# set gtpv2-priority-level 10
      2. Configure an upper limit for the memory load.
        [edit unified-edge cos-cac resource-threshold-profiles resource-threshold-1 memory high]user@host# set percentage 85 user@host# set gtpv1-arp 3 user@host# set gtpv2-priority-level 10
