Port Utilization Guide for Cisco Unified Contact Center Solutions, Release 12.5(1)

Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Port Utilization in Contact Center Enterprise

Port Utilization Table Columns

The columns in the port utilization tables in this document describe the following:

Listener (Process or Application Protocol)

A value representing the server or application and where applicable, the open or proprietary application protocol.

Listener Protocol and Port

An identifier for the TCP or UDP port that the server or application is listening on, along with the IP address for incoming connection requests when acting as a server.

Remote Device (Process or Application Protocol)

The remote application or device making a connection to the server or service specified by the protocol.

Remote Port

The remote port is used to make an outgoing connection to the corresponding listener port.

Traffic Direction

The direction that traffic flows through the port: Inbound, Bidirectional, Outbound.


Note

  • The operating system dynamically assigns the source port that the local application or service uses to connect to the destination port of a remote device. In most cases, this port is assigned randomly from unused ports in the ephemeral port range 1024 - 65535.

  • For security reasons, keep open only the ports mentioned in this guide and those required by your application. Keep the rest of the ports blocked.

Unified CCE and Packaged CCE Port Utilization

This table includes information for Unified CCE and CTI OS.

Some port definitions use a formula. For example:

TCP 40007 + (Instance Number * 40)

In this example, instance 0 uses port 40007, instance 1 uses port 40047, instance 2 uses port 40087, and so on.


Note

In the following table, PG1, PG2, and PG3 are not specific PG numbers or DMP IDs. They are the order in which the PGs get installed.


Note

This document does not include the Enterprise Chat and Email (ECE) port details. For more information on ECE ports, see the ECE documentation at: https://www.cisco.com/c/en/us/support/customer-collaboration/cisco-enterprise-chat-email/tsd-products-support-series-home.html.

For example, the first PG pair (PG1 Side A/B) installed, is assigned TIP base ports 42034 and 43034 respectively. The second PG pair (PG2 Side A/B) installed, is assigned ports 44034 and 45034 respectively. The same assignment is applicable to TOS ports as well.

These assume all server names are either TCP/IP addresses or DNS names (hence no NETBIOS port requirements).

Ports are also required to access all Unified Contact Center Management Portal servers for support reasons (either pcAnywhere or terminal services).


Note

This list does not include standard Windows ports such as DNS and Kerberos.

* MSDTC response ports by default use a dynamically allocated port in the range of 1024 to 5000. You can configure this range creating the HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\Internet location registry key and adding the following registry values:

  • Ports (REG_MULTI_SZ) - specify one port range per line, for example, 3000-3005

  • PortsInternetAvailable (REG_SZ) - always set this value to "Y" (do not include the quotes)

  • UseInternetPorts (REG_SZ) - always set this value to "Y" (do not include the quotes)
