Port availability for deployed operating systems
Some ports are blocked by certain operating-system profiles. The following tables list the ports that are open (not blocked).
Ensure that the hypervisor that is running the Lenovo XClarity Orchestrator appliance allows network traffic (TCP/UDP) on ports 139, 445, 3001, 3900, 8443. These are required for operating-system deployment.
RHEL Virtualization profile
By default, the Red Hat Enterprise Linux (RHEL) Virtualization profile blocks all ports except for those that are listed in the following table.
| Port | TCP or UDP | Direction | Communication description |
|---|---|---|---|
| 22 | TCP | Inbound | SSH communication |
| 53 | TCP, UDP | Outbound/Inbound | Communication with RHEL KVM networking devices |

| 22 | TCP | Inbound | SSH communication |
| 3001 | TCP | Outbound/Inbound | Management software image-deployment service communication |
SLES Virtualization, Basic, and Minimal profiles
For SUSE Linux Enterprise Server (SLES), some open ports are dynamically assigned based on the operating system version and profiles. For a complete list of open ports, see your SUSE Linux Enterprise Server documentation.
