Port Utilization Guide for Cisco Unified Contact Center Express Release 9.0(2)
This chapter contains the following sections:
- Port utilization table column definition
- Cisco Unified CCX port utilization
- Cisco Unified IP IVR port utilization
- Cisco agent/Supervisor desktop port utilization
Port utilization table column definition
The columns in the below tables describe the following:
- Destination port / Listener
- A numeric identifier that the Internet transport protocol uses to distinguish among multiple, simultaneous connections to a single destination host.
- Application / Process
- This is the process that is expected to provide the service using a port.
- Protocol
- It is a higher application level transport mechanism that defines the semantics of the messages being transported over a network. If you see TCP as the protocol, it means that the protocol is proprietary.
- Network protocol
- It is a lower level transport mechanism that is unaware of what is being transported over a network. TCP and UDP are the two transport protocols used here.
- Remote device
- The name of the devices that connect to the listed port.
- Source port
- The port using which a remote device connects to the listed port
- Purpose
- The service for which a particular port is used by the server.
- Traffic direction
- Direction of TCP/UDP packets between Unified CCX server and remote device.
Cisco Unified CCX port utilization
The following table lists ports that are used in Cisco Unified CCX.
Table 1 Cisco Unified CCX port utilization Bi-directional
Intra-Cluster Communication (see table note 1)
Cisco Agent Desktop (CAD), Cisco Supervisor Desktop (CSD), Cisco Desktop Workflow Administrator, CAD Browser Edition, CAD IP Phone Agent
Provide RTMT data collecting, logging and alerting functionalities (AMC RMI Object Port)
Provide RTMT data collecting, logging and alerting functionalities (AMC RMI Registry Port)
This is the port where the IDS engine listens for DB clients
- This is an alternate port to bring up a second instance of IDS during upgrade.
External process like HRC, WallBoard Client, External DB clients (like Squirrel or others for custom reporting) can connect
DBL RPC, this is used during installation to set up IDS replication between nodes
Real-Time Information Server (RIS) Data Collector service (RISDC)
Connect to other RISDC services in the cluster to provide cluster-wide real-time info
CAD, CSD, Cisco Desktop VoIP Monitor Service, Cisco Desktop Workflow Administrator, Intra-Cluster Communication
Note Port 38983 is open only on Unified CCX systems that were upgraded from versions earlier than 9.0(1).
CAD, Cisco Desktop VoIP Monitor Service, Intra-Cluster Communication
CAD, Cisco Desktop VoIP Monitor Service (under SPAN configurations)
DRF master agent server port accepts connections from local agent GUI and CLI
SOAP Monitor - a troubleshooting tool for SOAP infrastructure
Publish JMS events across JMS network connectors in the cluster
-Client browser trying to access any of the Administration interfaces or User Options interface.
-Web services client using RTMT and mobile supervisor applications.
Client browser trying to access the Cisco Unified Intelligence Center web interface
- Client browser trying to access any of the Administration interfaces or User Options interface
- Web services client using RTMT and mobile supervisor applications
Client browser trying to access the Cisco Unified Intelligence Center web interface
Cluster replication of platform data (hosts) certificates etc.
- Clients trying to access HTTP triggers or documents / prompts / grammars
Generic ephemeral TCP ports (see table note 2)
Generic ephemeral UDP ports (see table note 3)
Cisco Desktop VoIP Monitor Service (SPAN-based monitoring), CAD (desktop monitoring), Intra-Cluster Communication
Cisco Desktop VoIP Monitor Service (SPAN-based monitoring), CAD (desktop monitoring), Intra-Cluster Communication
Cisco Desktop Licensing and Resource Manager Upgrade Service
Table notes
- Intra-Cluster communication in the table represents communication between Unified CCX servers in a cluster.
- TCP Ephemeral ports are used to accept connections during Java RMI communication. Java RMI clients know which port it need to connect, because RMI first connects to RMI Registry (well known port - 6999) and get the information which ephemeral port client need to connect to. AppAdmin, Engine & CVD use RMI communication in CCX/IP-IVR, so TCP ephemeral port range is opened up for intra-cluster communication between these processes.
- UDP Ephemeral ports are used to receive audio/video RTP streams; so UDP Ephemeral port range is opened for incoming connections for streaming RTP media from CTI ports.
Cisco Unified IP IVR port utilization
The following table lists ports that are used in Cisco Unified IP IVR.
Table 2 Cisco Unified IP IVR port utilization Intra-Cluster communication (see table note 1)
Provide RTMT data collecting, logging and alerting functionalities (AMC RMI Object Port)
Provide RTMT data collecting, logging and alerting functionalities (AMC RMI Registry Port)

DRF master agent server port accepts connections from local agent GUI and CLI
Using this port Unified ICM Subsystem listens to GED-125Clients. This port is modifiable.
SOAP Monitor - a troubleshooting tool for SOAP infrastructure

Cisco agent/Supervisor desktop port utilization
There are few ports that are listening on Cisco Desktop clients. This applies to non-Citrix/MTS environments only and does not include other connections that are made with ephemeral ports. The following table provides information regarding these fixed client ports.
The columns in the tables below describe the following:
- Port
- A numeric identifier that the internet transport protocol uses to distinguish among multiple, simultaneous connections to a single destination host.
- Process
- This is the process that is expected to provide the service using a port.
- Network protocol
- It is a lower level transport mechanism that is unaware of what is being transported over a network. TCP and UDP are the two transport protocols used here.
- Port utilization
- The device/process that utilizes this port .
- Comments
- Additional information.
- Traffic direction
- Direction of TCP/UDP packets between Cisco Desktop Clients and remote device(s).
