Protocol and port requirements

Using a browser, API client, or SSH, the required ports must be accessible to the Unified Manager UI and APIs. The required ports and protocols enable communication between the Unified Manager server and the managed storage systems, servers, and other components.

Connections to the Unified Manager server

You do not have to specify port numbers when connecting to the Unified Manager web UI, because default ports are always used. For example, because Unified Manager always runs on its default port, you can enter https://<host> instead of https://<host>:443. The default port numbers cannot be changed.

The Unified Manager server uses specific protocols to access the following interfaces:

Interface Protocol Port Description
Unified Manager web UI HTTP 80 Used to access the Unified Manager web UI; automatically redirects to the secure port 443.
Unified Manager web UI and programs using APIs HTTPS 443 Used to securely access the Unified Manager web UI or to make API calls; API calls can only be made using HTTPS.
Maintenance console SSH/SFTP 22 Used to access the maintenance console and retrieve support bundles.
Red Hat Enterprise Linux command line SSH/SFTP 22 Used to access the Red Hat Enterprise Linux command line and retrieve support bundles.
MySQL database MySQL 3306 Used to enable OnCommand Workflow Automation and OnCommand API Services access to Unified Manager.
Syslog UDP 514 Used to listen to and access EMS messages from ONTAP clusters and to create events based on the messages.

Connections from the Unified Manager server

You must configure your firewall to open ports that enable communication between the Unified Manager server and managed storage systems, servers, and other components. If a port is not open, communication fails.

Depending on your environment, you can choose to modify the ports and protocols used by the Unified Manager server to connect to specific destinations.

The Unified Manager server connects using the following protocols and ports to the managed storage systems, servers, and other components:

Destination Protocol Port Description
Storage system HTTPS 443/TCP Used to monitor and manage storage systems.
AutoSupport server HTTPS 443 Used to send AutoSupport information. Requires Internet access to perform this function.
Authentication server LDAP 389 Used to make authentication requests, and user and group lookup requests.
LDAPS 636 Used for secure LDAP communication.
Mail server SMTP 25 Used to send alert notification emails.
SNMP trap sender SNMPv1 or SNMPv3 162/UDP Used to send alert notification SNMP traps.
External data provider server TCP 2003 Used to send performance data to an external data provider, such as Graphite.
NTP server NTP 123/UDP Used to synchronize the time on the Unified Manager server with an external NTP time server. (VMware system only)
