Cisco Systems D14595.03 manual Ports for streaming from the Content Server

Port information

Ports for streaming from the Content Server

Streaming Windows Media from the Content Server uses the following ports:

Port	Streaming Media Protocol	Firewall Information
554	RTSP	At least one of these ports needs to be open
		between the Content Server and the Windows
8080	HTTP
		Media player. For true (RTSP) streaming, open
		port 554. See the note below.

Note: The Windows Media player will automatically use protocol rollover if necessary. The default streaming protocol for the Windows Media player is RTSP on port 554. If the player cannot obtain the stream using RTSP (because the port is blocked on a firewall, for example), then it will automatically rollover to MMS. MMS (port 1755) is a deprecated streaming protocol and is not used as a streaming transport for Windows Media Player version 9 and above. The player will then try HTTP on port 80. The Content Server will redirect any requests for Windows Media streams on port 80 to the correct HTTP port used by the Windows Media Streaming Server on the Content Server (port 8080).

Streaming Windows Media from the Content Server to the Silverlight player uses the following port:

Port	Streaming Media Protocol	Firewall Information
8080	HTTP	Needs to be open between the Content Server
		and the Silverlight player.

Note: The Silverlight player will request the stream on port 80 because this is the default HTTP port. The Content Server will redirect any requests for Windows Media streams on port 80 to the correct HTTP port used by the Windows Media Streaming Server on the Content Server (port 8080).

Serving MPEG-4 for QuickTime, MPEG-4 for Flash or Real Media from Content Server using the default "Local IIS Web Server" Media server configuration uses the following port:

Ports for streaming from external streaming servers

The default setup for a Windows Media Streaming Server uses the following ports:

Port	Streaming Media Protocol	Firewall Information
554	RTSP	At least one of these ports needs to be open
		between the Content Server and the Windows
80	HTTP
		Media player. For true (RTSP) streaming, open
		port 554. See the note below.
		If using server push in the Media server
		configuration, ensure that the HTTP port is open
		between the Content Server and the external
		streaming server.
