Defining UPF Selection Query Parameters
Use the following configuration to define the UPF selection policy specific configuration.
configure
policy upf-selection upfpolicy_name
precedence priority_value [ dcnr | dnn | pdn-type-session | pdn-type-subscription ]
end
NOTES:
-
configure : Enters the global configuration mode.
-
policy upf-selection upfpolicy_name : Specifies the UPF policy name that must be 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 [ dcnr | dnn | pdn-type-subscription | pdn-type-session ] : Assigns the precedence value to the UPF policy. Specifies the DNN and other parameters for the UPF selection. The precedence keyword allows a maximum of four precedence values to be configured under the UPF selection policy.
If the DNN profile does not have any UPF selection policy associated with it, then the SMF performs UPF selection using DNN, priority, and load information.
