Configuring Index and Session Count for UPF Selection

To define the UPF index value and maximum session count for co-located UPF selection, use the following sample configuration.

config 
   profile converged-core cc_profile_name 
      max-upf-index upf_index_value 
      max-session-count up_session_count 
      end 

NOTES:

  • profile converged-core cc_profile_name : Specify the name of the converged core profile. This keyword allows you to enter the converged core profile configuration mode.

  • max-upf-index upf_index_value : Specify the maximum number of supported UPF index values for UPF selection.

    upf_index_value must be an integer in the range of 0–1023.

    The SMF validates the configured UPF index value against the UP ID received in the N4 Association Setup request from UPF. If the validation fails, the SMF rejects the corresponding request. If the validation is successful, the SMF acknowledges the request and stores the UP ID along with other UPF details.

  • max-session-count up_session_count : Specify the maximum number of UP sessions supported.

    up_session_count must be an integer in the range of 1000000–12000000. Default value is 1000000.

    The SMF uses the configured session count to associate the UP session with IdMgr context. Note that IdMgr maintains a separate context per million UP sessions.
