Port availability

Several ports must be available, depending on how the firewalls are implemented in your environment. If the required ports are blocked or used by another process, some Lenovo SDI Management Platform functions might not perform correctly.

If Lenovo SDI Management Platform and all managed devices are behind a firewall, and you intend to access those devices from a browser that is outside of the firewall, you must ensure that the following ports are open.

Lenovo SDI Management Platform listens on and responds through the ports that are listed in the following table.

Note:

  • Lenovo SDI Management Platform is a RESTful application. DNS (TCP/UDP on port 53) communicates securely over TCP on port 443.

  • Lenovo SDI Management Platform 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.
