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.
