Configuring UPF Ingress Interface Type

To configure the UPF ingress interface type, use the following configuration:

To enable the upf-ingress command, you must configure the require upf command on the UPF. You need the UPF license to enable the require upf command.

configure 
   context context_name 
      user-plane-service service_name 
         [ no ] associate gtpu-service gtpu_service_name upf-ingress interface-type [ n9 | s5u | s8u | n3  | n9-s5u-s8u  ] 
         end 

NOTES:

  • associate gtpu-service gtpu_service_name : Associate the GTP-U service with the user plane service.

  • upf-ingress : Configure the interface type as UPF ingress.

  • interface-type [ n9 | s5u | s8u | n3 | n9-s5u-s8u ] : Configure the desired GTP-U ingress interface type.

  • If the N3 GTP-U ingress service is not present, UPF uses the default interface.

  • If the configuration for N9, S5u, or S8u interfaces is not present, UPF performs the following actions:

    • UPF looks to use the N9 interface first followed by the S5u and S8u interfaces.

    • If there is no GTP-U service, UPF uses the default interface.
