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 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.
