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.
