Feature Description

This feature supports Access Point Name (APN) or Data Network Name (DNN) profile for the SGW (cnSGW-C) service. DNN is equivalent to APN in Evolved Packet System (EPS).

Using the Operator Policy and the Subscriber map, you can determine the DNN Profile for the cnSGW-C service.

Feature Configuration

Configuring this feature involves the following steps:

Configuring DNN Profile

To configure this feature, use the following configuration:

config 
   profile dnn dnn_name 
      upf-selection-policy upf_select_name 
        dnn dnn_name network-function-list network_function_list 
        end

NOTES:

  • dnn dnn_name —Specify the DNN profile name. Must be a string.

  • upf-selection-policy upf_select_name —Specify the UPF selection policy name. Must be a string.

  • network-function-list network_function_list —Specify the list of network functions to which the selected DNN profile is sent. Must be a string.

Configuring Network Element Profile

Network element profile represents peer IP (UPF) profile and has the following configurations:

  • Peer address and Port configuration

  • Peer-supported DNNs or APNs. This configuration helps in UPF selection.

UPF selection considers priority and capacity parameters.

upf-group-profile indicates the UPF group to which it belongs.

To configure this feature, use the following configuration:

config 
   profile network-element upf upf_name 
     node-id  node_id_value 
     n4-peer-address ipv6 ipv6_address 
     n4-peer-address ipv4 ipv4_address 
     n4-peer-port port_number 
     dual-stack-transport { true | false }  
     dnn-list dnn_list 
     capacity capacity_value 
     priority priority_value 
     upf-group-profile upf_group_name 
     end

NOTES:

  • network-element —Specify the peer network element.

  • upf upf_name—Specify the UPF peer name.

  • node-id node_id_value —Specify the Node ID of the UPF node.

  • n4-peer-address ipv4 ipv4_address —Specify the IPv4 address.

  • n4-peer-address ipv6 ipv6_address —Specify the IPv6 address.

  • n4-peer-port port_number —Specify the N4 peer port number. Must be an integer in the range of 0-65535.

  • dual-stack-transport { true | false } —Enable the dual stack feature that allows you to specify IPv6 or IPv4 address. Specify true to enable this feature.

  • dnn-list dnn_list —Specify the DNN list supported by UPF node.

  • capacity capacity_value —Specify the capacity relative to other UPFs. This is used for load balancing. Must be an integer in the range of 0-65535. Default value is 10.

  • priority priority_value —Specify the static priority relative to other UPFs. This is used for load balancing. Must be an integer in the range of 0-65535. Default value is 1.

  • upf-group-profile upf_group_name —Specify the UPF group profile name. Must be a string.
