Ports

This document provides lists of the ports used by Cisco Virtualization Experience Media Engine, and also by Virtualization Experience Client Manager and by Cisco Jabber. If your network includes firewalls between any of these components, you must open these ports. Configuration of firewalls, ACLs, or QoS varies depending on topology, placement of devices and services relative to the placement of network security devices, and depending on which applications and telephony extensions are in use.


Note


Cisco has not verified all possible configuration scenarios for these ports. If you are having configuration problems using these lists, contact Cisco technical support for assistance.

Ports Usage
22 SSH connections.
69 Outbound traffic for TFTP.

HTTP

80

280

Communicate with the Web Service and Standard Service.

 

FTP

Register new packages into the Master Software Repository.

Note   

Although FTP uses port 21 as the control port, by default it also uses additional ephemeral ports for data transfers. To allow the data transfers to clients located behind a firewall or Cisco Virtual Office router, you must open these additional ports in the firewall or Cisco Virtual Office router. This requirement is standard for FTP connections, and is not specific to the implementation of Cisco VXC Manager.

 

OLE DB

1433 (default)

Can be configured during installation

Communicate with the Cisco VXC Manager Database.

 

VNC

5800

5900

Remote shadows devices.

This requirement is standard for FTP connections, and is not specific to the implementation of Cisco VXC Manager.

Standard Service and legacy support for older Cisco VXC Manager Agents

UDP

8191

TCP

Connects to the local port to provide Simple Object Access Protocol (SOAP) web services.

8443

HTTPS

8443 is the port for web access to Cisco Unified Communications Manager and includes connections for the following:

  • Cisco Unified Communications Manager IP Phone (CCMCIP) server for assigned devices.
  • User Data Service (UDS) for contact resolution.

16384 to 32766

UDP

Sends RTP media streams for audio and video.

53

DNS

Provides hostname resolution.

1080

SOCKS5 Bytestreams

Sends peer to peer file transfers. If port 1080 is in use, Cisco Jabber for Windows attempts to use the next available port in the range from 1081 to 1089. In on-premises deployments, Cisco Jabber for Windows also uses this port to send screen captures.

ICMP requests

Cisco Jabber for Windows sends Internet Control Message Protocol (ICMP) requests to the TFTP server. Cisco Jabber uses these requests to determine whether it can connect to Cisco Unified Communications Manager. Therefore, you must configure your firewall settings to allow ICMP requests from the client. If your firewall does not allow ICMP requests, Cisco Jabber for Windows cannot establish a connection to Cisco Unified Communications Manager.
