WebSphere Application Server port usage

The WebSphere Application Server environment utilizes several TCP/IP ports for various functions.

When you configure WebSphere Application Server resources or assign port numbers to other applications, avoid conflicts with other assigned ports. In addition, when you configure a firewall, explicitly enable access to particular port numbers.

Notes:

• For more information about port numbers that your iSeries system currently uses, enter the NETSTAT *CNN command on the OS/400 command line. Press F14 to view assigned port numbers.
• You can also use the port validator tool to find port conflicts between different WebSphere Application Server instances, products, and servers. For information about the tool, see The port validator tool.

These topics describe the TCP/IP ports that the WebSphere Application Server and WebSphere Application Server Network Deployment environments use.

WebSphere Application Server default port definitions
This topic describes the default ports assigned to WebSphere Application Server instances.

WebSphere Application Server Network Deployment deployment manager default port definitions
This topic describes the default ports assigned to deployment managers in WebSphere Application Server Network Deployment.

WebSphere Application Server node agent default port definitions
When you federate an application server node into a deployment manager cell, the deployment manager creates a node agent server on the application server node. This topic describes the default ports assigned to node agents.

WebSphere Application Server JMS server default port definitions
When you federate an application server node which uses embedded JMS into a deployment manager cell, the deployment manager creates a JMS server on the application server node. This topic describes the default ports assigned to Java Message Service (JMS) servers.
