An NGAP ID and a Serving-Temporary Mobile Subscriber Identity (S-TMSI) are assigned to a UE within AMF. Using these unique values, the UE is distinguished over the NG interface. The Node Manager (NodeMgr) pod manages these unique IDs by generating and allocating them to the UE through the request and response messages.

To configure this feature, use the following configuration:

config 
    instance instance-id instance-id 
      endpoint { bgpspeaker | geo | gtp | li | ngap | nodemgr | protocol | sbi | sctp | service } 
        instancetype { Dual | IPv4 | IPv6 } 
        interface { bfd | bgp | geo-external | geo-internal | nrf } 
        internal base-port start port_number 
        loopbackEth host_address_port_number 
        loopbackPort port_number 
        nodes number_of_nodes 
        range { vip-ipv6 ipv6_address | offline offline| vip-ipv6-port ipv6_address } 
        replicas number_of_nodes 
        system-health-level { crash | critical | warn }  
        uri-scheme { http | https }  
        vip-ip ipv4_address 
        vip-ipv6 ipv6_address 
        end  

NOTES:

• instance instance-id instance-id —Specify the endpoint instance ID.

• endpoint { bgpspeaker | geo | gtp | li | ngap | nodemgr | protocol | sbi | sctp | service } —Specify the endpoint that must be configured. For configuring NodeMgr, use nodemgr .

• instancetype { Dual | IPv4 | IPv6 } —Specify the endpoint's local interface type.

• interface { bfd | bgp | geo-external | geo-internal | nrf } —Specify the endpoint interfaces.

• internal base-port start port_number —Specify the internal base-port to start the endpoint.

• loopbackEth host_address_port_number —Specify the local interface name or host IP address of the endpoint.

• loopbackPort port_number —Specify the endpoint local port.

• nodes number_of_nodes —Specify the number of nodes replicas that must be configured for resiliency.

• range { vip-ipv6 ipv6_address | offline offline | vip-ipv6-port ipv6_address } —Specify the range of the NodeMgr endpoint.

• replicas number_of_nodes —Specify the number of replica nodes that must be created for the endpoint.

• system-health-level { crash | critical | warn } —Specify the message to indicate the health of the system.

• uri-scheme { http | https } —Specify the URI scheme as HTTP or HTTPs.

• vip-ip ipv4_address —Specify the IPv4 address for the endpoint.

• vip-ipv6 ipv6_address —Specify the IPv6 address for the endpoint.
