Cisco Intercompany Media Engine
Release 8.0(2) TCP and UDP Port Usage
This document provides a list of the TCP and UDP ports that Cisco Intercompany Media Engine Release 8.0(2) uses for intracluster connections and for communications with external applications or devices. It provides important information for the configuration of firewalls, Access Control Lists (ACLs), and quality of service (QoS) on a network when an IP Communications solution is implemented.
Note Cisco has not verified all possible configuration scenarios for these ports. If you are having configuration problems using this list, contact Cisco technical support for assistance.
While virtually all protocols are bidirectional, this document gives directionality from the session originator perspective. In some cases, the administrator can manually change the default port numbers, though Cisco does not recommend this as a best practice. Be aware that Cisco IME opens several ports strictly for internal use.
Ports in this document apply specifically to Cisco Intercompany Media Engine Release 8.0(2). Some ports change from one release to another, and future releases may introduce new ports. Therefore, make sure that you are using the correct version of this document for the version of Cisco IME that is installed.
Installing Cisco Intercompany Media Engine 8.0(2) software automatically installs the following network services for serviceability and activates them by default. Refer to Table 1 for details:
•Cisco Log Partition Monitoring (To monitor and purge the common partition. This uses no custom common port.)
•Cisco Trace Collection Service (TCTS port usage.)
•Cisco RIS Data Collector (RIS server port usage)
•Cisco AMC Service (AMC port usage)
Configuration of firewalls, ACLs, or QoS will vary depending on topology, placement of telephony devices and services relative to the placement of network security devices, and which applications and telephony extensions are in use. Also, bear in mind that ACLs vary in format with different devices and versions.
