Connection and port requirements

You should ensure that the connections and ports requirements are met before installing the SnapCenter Server and application or database plug-ins.

SnapCenter uses the following default ports:

Type of port Default port
SnapCenter port 8146 (HTTPS), bidirectional, customizable, as in the URL https://server:8146

Used for communication between the SnapCenter client (the SnapCenter user) and the SnapCenter Server. Also used for communication from the plug-in hosts to the SnapCenter Server.

SnapCenter SMCore communication port 8145 (HTTPS), bidirectional, customizable

The port is used for communication between the SnapCenter Server and the hosts where the SnapCenter plug-ins are installed.

MySQL port 3306 (HTTPS), bidirectional

The port is used for communication between SnapCenter and MySQL repository database.

You can create secured connections from the SnapCenter Server to the MySQL server. Details are in the Administration Guide.

Performing administrative tasks

Windows plug-in hosts 135, 445 (TCP)

In addition to ports 135 and 445, the dynamic port range specified by Microsoft should also be open. Remote install operations use the Windows Management Instrumentation (WMI) service, which dynamically searches this port range.

For information on the dynamic port range supported, see Microsoft Support Article 832017: Service overview and network port requirements for Windows

The ports are used for communication between the SnapCenter Server and the host where the plug-in is being installed. To push plug-in package binaries to Windows plug-in hosts, the ports must be open only on the plug-in host, and they can be closed after installation.

Linux plug-in hosts 22 (SSH)

The ports are used for communication between the SnapCenter Server and the host where the plug-in is being installed. The ports are used by SnapCenter to copy plug-in package binaries to Linux plug-in hosts and should be open or excluded from the firewall or iptables.

SnapCenter Plug-ins Package for Windows 8145 (HTTPS), bidirectional, customizable

The port is used for communication between SMCore and hosts where the SnapCenter plug-ins package for Windows is installed.

The communication path also needs to be open between the SVM management LIF and the SnapCenter Server.

SnapCenter Plug-ins Package for Linux 8145 (HTTPS), bidirectional, customizable

The port is used for communication between SMCore and hosts where the SnapCenter plug-ins package for Linux is installed.

The communication path needs also to be open between the SVM management LIF and the SnapCenter Server.
Custom plug-ins for SnapCenter 9090 (HTTPS), fixed

This is an internal port that is used only on the custom plug-in host; no firewall exception is required.

Communication between the SnapCenter Server and custom plug-ins is routed through port 8145.

ONTAP cluster or SVM communication port 443 (HTTPS), bidirectional

80 (HTTP), bidirectional

The port is used by the SAL (Storage Abstraction Layer) for communication between the host running SnapCenter Server and SVM. The port is currently also used by the SAL on SnapCenter for Windows Plug-in hosts for communication between the SnapCenter plug-in host and SVM.

SnapCenter Plug-in for SAP HANA Database ports

3instance_number13 or 3instance_number15, HTTP or HTTPS, bidirectional, and customizable

For a multitenant database container (MDC) single tenant, the port number ends with 13; for non MDC, the port number ends with 15.

For example, 32013 is the port number for instance 20 and 31015 is the port number for instance 10.
