Configuring the UPF-Selection Policy

This section describes how to configure the upf-selection policy.

Use the following to configure the UPF-Selection policy within the DNN policy.

  config 
     profile dnn profile_name 
       upf-selection-policy upf_policy 
          precedence priority_value [ dnn | slice |
          pdn-type-subscription | pdn-type-session | dcnr ] 
          end 

NOTES:

  • config – Enters the configuration mode.

  • profile dnn profile_name – Specifies the DNN profile name. profile_name must be an alphanumeric string.

  • upf-selection-policy upf_policy – Specifies the UPF policy. The upf-selection-policy is associated with the dnn-profile. The SMF selects the UPF node with the lowest precedence value. The SMF selects the node with the highest precedence selection-criteria when the previous lower precedence criteria did not return any UPF. If the configured criteria are exhausted, and nodes are not selected, then the upf-selection policy fails.

    Within the precedence value, the intersection of UPFs from each criterion is performed to retrieve the UPF list.

  • precedence priority_value [ dnn | slice | pdn-type-subscription | pdn-type-session | dcnr ] – Assigns the precedence value to the UPF policy. Specifies the DNN and other parameters for the UPF selection. The precedence supports maximum of 4 precedence under the upf-selection policy.

    If the dnn-profile does not have any upf-selection-policy associated with it, then the upf-selection is performed using DNN, priority, and load information.
