NSMADM-CA Messaging Overview

Messaging and Data Transport

CA NSM employs the following primary data transport mechanisms to transfer data between CA NSM enabled nodes:

Distributed Intelligent Architecture (DIA)
CA Message Queuing Service (CAM)

Other legacy communications mechanisms may also be supported by CA NSM for the purposes of backwards compatibility.

To support these communication mechanisms, certain ports in a firewall must be open.

Note: CA is committed to reducing the number of ports that are required to use CA NSM. For this reason, we have identified the ports that are required and the ports that are optional. CA Technology Services can help you design the best port solution for your enterprise.

Required Open Ports

This table provides a list of the ports that are required to be open in a firewall to support basic communication among CA NSM components.

Component	Default Port	Port Type	Install checks if default port is in use?	Install prompts for different port if conflict exists?	Comments
CA Common Communications Interface (CAICCI)	1721	TCP	Y	Y	CA IANA registered CAICCI listener port (CCI Remote Service).
CAM	4104	UDP	Y	Y	Used for System Performance, Continuous Discovery.
DIA	5635	TCP	N	N	Used for MCC to Manager communication
DIA	5636	TCP	N	N	Used for MCC to Manager communication
CA Common Communications Interface (CAICCI)	7001	TCP	Y	Y	Required for NSM communications that use CCI between Windows servers.
Apache Tomcat	9090	TCP	Y	N	Services incoming requests by component applications that expose functionality through Tomcat, such as Unicenter Web Reporting Server.
Apache Tomcat	9005	TCP	Y	N	Used when Tomcat waits for a shutdown command.
DIA	11501	TCP	N	N	Only requires firewall to open outbound
DIA	11502	TCP	N	N	Only requires firewall to open outbound
DIA	11503	TCP	N	N	Only requires firewall to open outbound
DIA	11504	TCP	N	N	Used by DIA for manager to manager communication
Ingres Remote Client	19016	TCP	Y	Y	Used to communicate with MDB server if you are using an Ingres database. Port number is bound to Ingres instance name. Default code is EI, but can be changed at installation.

NSMADM-Optional Ports

This table provides a list of the optional ports that are required to be open in a firewall to support only certain low-level features or compatibility with a previous version. These ports are grouped by their specific component in the Ports by Component section.

Component	Default Port	Port Type	Install checks if default port is in use?	Install prompts for different port if conflict exists?	Comments
Non-CA agents, Enterprise Management	162	UDP	N	N	Native SNMP traps sent to DSM policy. Required to receive traps from non-CA agents. Additionally, Enterprise Management requires this port if Trapmux is used to support SNMP V3.
CAM	4105	TCP	Y	Y	Used for System Performance, Continuous Discovery, CAM. This port needs to be opened in a firewall only if the CAM communications method is set to TCP. Default mode of operation among computers is UDP.
Enterprise Management	6161	UDP	N	Y	When trapmux is active, used as the catrapd command port.
Enterprise Management	6163	UDP	N	Y	If Trapmux is being used (SNMP v3 support is activated), catrapd opens this port on which to listen
Agent Technology	6665	UDP	N	N	Used only if DIA is not installed
Mobile Services	8888	TCP	N	N	Used for communications between a CA NSM manager and Pocket PC devices. Disabled by default. If Pocket PC connectivity is required, Mobile Services must be activated and this port opened.
CA Common Communications Interface (CAICCI)	7000	TCP	N	N	Default for AP/OPS interface component. Configurable at site. In field since 2000. Is not required if all nodes are at r11 or higher.
Agent Technology	7774	TCP	N	N	Required when using Agent Technology processes using the -@ option.
