Port availability

Lenovo XClarity Orchestrator and resource managers require certain ports to be open to facilitate communication. If the required ports are blocked or used by another process, some functions might not perform correctly.

XClarity Orchestrator, Lenovo XClarity Management Hub 2.0, Lenovo XClarity Management Hub, and Lenovo XClarity Administrator are a RESTful applications that communicates securely over TCP on port 443.

XClarity Orchestrator​

XClarity Orchestrator listens on and responds through the ports that are listed in the following table. If XClarity Orchestrator and all managed resources are behind a firewall, and you intend to access those resources from a browser that is outside of the firewall, ensure that the required ports are open.

Note
XClarity Orchestrator can be optionally configured to make outbound connections to external services, such as LDAP, SMTP, or syslog. These connections might require additional ports that are generally user configurable and not included in this list. These connections might also require access to a domain name service (DNS) server on TCP or UDP port 53 to resolve external server names.

XClarity Management Hub 2.0​

Lenovo XClarity Management Hub 2.0 requires certain ports to be open to facilitate communication. If the required ports are blocked or used by another process, some management hub functions might not perform correctly.

If devices are behind a firewall and if you intend to manage those devices from a management hub that is outside of that firewall, you must ensure that all ports involved with communications between the management hub and the baseboard management controller in each device are open.

  1. When using XClarity Management Hub to manage devices through XClarity Orchestrator, certain ports must be open to facilitate communication. If the required ports are blocked or used by another process, some XClarity Orchestrator functions might not perform correctly.
  2. XClarity Management Hub can be optionally configured to make outbound connections to external services. These connections might also require access to a domain name service (DNS) server on TCP or UDP port 53 to resolve external server names.

  3. If manageable devices are behind a firewall and if you intend to manage those devices from a XClarity Management Hub that is outside of that firewall, you must ensure that all ports involved with communications between the XClarity Management Hub and the edge devices are open.

XClarity Administrator​

When using Lenovo XClarity Administrator to manage devices through Lenovo XClarity Orchestrator, certain ports must be opened to facilitate communication. If the required ports are blocked or used by another process, some XClarity Orchestrator functions might not perform correctly.

For information about the ports that must be opened for XClarity Administrator, see Port availability in the XClarity Administrator online documentation.
