Open Ports and Services
The SMF uses different ports for communication purposes. The following table describes the default open ports and the associated services.
Port | Service | Usage |
---|---|---|
9003 | gRPC | This is the default gRPC port for all the application pods that aren’t using the host network. |
8080 | TCP/HTTP | This is the default prometheus server port for all the application pods that aren’t using the host network. |
8090 | TCP/HTTP | SMF uses the HTTP2 REST endpoint for the SBI interface endpoint. |
2024 | SSH | SMF Ops Center uses this port to provide the ConfD CLI access. |
2379-2380 | TCP | SMF uses the etcd server client endpoint to store and retrieve system data. |
8882 | gRPC | This is the CDL session DB endpoint used by all other application pods. |
8890 | gRPC | Application REST endpoint uses this port to receive the call-back timer or notification from the CDL. |
8883 | gRPC | This is the TLS - CDL session DB endpoint used by all other application pods. |
2123 | UDP | SMF uses the 3GPP standard GTP-C port for the signaling of GTP-C protocol messages (control path). |
2152 | UDP | SMF uses the 3GPP standard GTP-U port for the signaling of GTP-U protocol messages (data path). |
8805 | UDP | SMF uses the 3GPP standard PFCP port for the signaling of PFCP protocol messages. |
8765 | TCP6 | SMF uses this port as the readiness probe port for the UDP proxy pod. |
7179, 7189 | TCP/HTTP | Pprof Server endpoint serves runtime profiling data from GTP-C endpoint interface-specific pods, such as S11 and S5. |
23300, 23310 | TCP/gRPC | SMF uses the TLS GRPC IPC server endpoint for the GTP-C endpoint interface-specific pods. |
9005, 9015 | TCP/gRPC | Non-TLS GRPC IPC server port for the GTP-C endpoint interface-specific pods. |
27000, 27010 | TCP | SMF uses the KeepAliveD endpoint for GTP-C endpoint interface-specific pods. |
7279, 7289 | TCP | This port is the admin endpoint internal port that is used in the GTP-C endpoint interface-specific pods. This port is used for liveness and readiness probe. |
7079, 7089 | TCP/HTTP | SMF uses the prometheus server port for the GTP-C endpoint interface-specific pods. |
8083 | TCP/HTTP | SMF uses the prometheus server port for the protocol pod. |
9006 | TCP/gRPC | SMF uses the non-TLS GRPC IPC Server endpoint for the protocol pod. |
8003 | TCP/HTTP | SMF uses the prometheus server port for the protocol pod. |
23100 | TCP/gRPC | SMF uses the TLS GRPC IPC server endpoint for the protocol pod. |
7679 | TCP/HTTP | The Pprof server endpoint serves runtime profiling data from the protocol pod. |
7879 | TCP | This port is the admin endpoint internal port that is used in the protocol pod. This port is used for the liveness and readiness probe. |
27500 | TCP | SMF uses this KeepAliveD endpoint for the protocol pod. |
28000 | TCP | SMF uses this KeepAliveD endpoint for the UDP proxy pod. |
23200 | TCP/gRPC | SMF uses the TLS GRPC IPC server endpoint for the UDP proxy pod. |
9004 | TCP/gRPC | Non-TLS GRPC IPC server endpoint for the UDP proxy pod. |
7879 | TCP | This port is the admin endpoint internal port that is used in the UDP proxy pod. This port is used for the liveness and readiness probe. |
8850 | TCP/HTTP | The Pprof server endpoint serves runtime profiling data from the UDP proxy pod. |
In addition to the preceding ports, SMF uses the ports that are destined for SMI for routing information between hosts. For information on SMI ports, see the Ultra Cloud Core Subscriber Microservices Infrastructure Operations Guide.
