Protocol and port requirements

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

In typical installations 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 attempts to run on its default port, you can enter https://<host> instead of https://<host>:443.

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.

Linux command line

SSH/SFTP

22

Used to access the Red Hat Enterprise Linux or CentOS 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 access subscription-based EMS messages from ONTAP systems and to create events based on the messages.

REST

HTTPS

9443

Used to access realtime REST API-based EMS events from authenticated ONTAP systems.
Note

The default port for MySQL, 3306, is restricted only to localhost while installing Unified Manager on Linux systems. This does not impact any upgrade scenario, where the previous configuration is maintained. This configuration can be modified, and the connection can be made available to other hosts by using the Control access to MySQL port 3306 option on the maintenance console. For information, see Additional menu options. The ports used for HTTP and HTTPS communication (ports 80 and 443) can be changed using the Unified Manager maintenance console. For more information, see Maintenance console menus.

Connections from the Unified Manager server

You should 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.

Storage system

NDMP

10000/TCP

Used for certain Snapshot restore operations.

AutoSupport server

HTTPS

443

Used to send AutoSupport information. Requires the 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 systems only)
