Open Ports and Services
The AMF uses different ports for communication. The following table describes the default open ports and the associated services.
Port |
Service |
Usage |
---|---|---|
22 |
SSH |
SMI uses TCP port to communicate with the virtual machines. |
80 |
HTTP |
SMI uses TCP port for providing Web access to CLI, Documentation, and TAC. |
443 |
SSL/HTTP |
SMI uses TCP port for providing Web access to CLI, Documentation, and TAC. |
6443 |
HTTP |
SMI uses port to communicate with the Kubernetes API server. |
9100 |
jetdirect |
SMI uses TCP port to communicate with the Node Exporter. Node Exporter is a Prometheus exporter for hardware and OS metrics with pluggable metric collectors. It allows you to measure various machine resources, such as memory, disk, and CPU utilization. |
10250 |
SSL/HTTP |
SMI uses TCP port to communicate with Kubelet. Kubelet is the lowest level component in Kubernetes. It is responsible for what is running on an individual machine. It is a process watcher or supervisor focused on active container. It ensures the specified containers are up and running. |
10256 |
HTTP |
SMI uses TCP port to interact with the Kube proxy. Kube proxy is a network proxy that runs on each node in your cluster. Kube proxy maintains network rules on nodes. These network rules allow network communication to your pods from network sessions inside or outside of your cluster. |
2024 | SSH | AMF Ops Center uses this port to provide the ConfD CLI access. |
9090 | HTTP | AMF REST endpoint pods use this port to expose the APIs to support NRF interface specific CLIs. |
8090 | HTTP | AMF REST endpoint pods use this port for routing incoming SBI messages to REST-EP pods. |
8890 |
gRPC/HTTP |
AMF REST endpoint pods use this port to receive timer notification from CDL. |
3179 |
Tcpwrapped |
SMI uses this TCP port for Calico(Kubernetes networking). Calico is used for routing the networking packets to pods. |
In addition to the preceding ports, AMF uses the ports that are destined for SMI for routing information between hosts. For more information on SMI ports, see Ultra Cloud Core Subscriber Microservices Infrastructure Operations Guide.
