This document describes how to configure the Cisco Cache/Content Engine for transparent and proxy media
caching using Web Cache Coordination Protocol (WCCP) version 2. Cisco ACNS Release 4.x, includes, as an

to support both stream splitting (distributing live feeds)
and streaming media caching (on−demand content) in both Real−Time Streaming Protocol (RTSP)−based
streaming and other Real PNM (RealNetworks metafile) formats.
streaming and other Real PNM (RealNetworks metafile) formats.
The Content Engine can be configured to transparently accept RTSP requests redirected from the WCCP
router, as well as traditional proxy−style RTSP requests from RealPlayer client software. Streaming media
caching provides content on demand to the extend that, if a user has already viewed a cached streaming media
file, it can be served to subsequent users without the requirement to connect to the origin server. Be aware that
live broadcasts cannot be cached.

To configure the Content Engine to accept RTSP traffic, complete these steps:
Issue the rtsp proxy command in global configuration mode for entering the IP address, port, and the
license used in the RealProxy of the Content Engine.

Streaming media objects are cached in the media file system (mediafs) disk partitions while the RealProxy
software is copied to the software file system (swfs) partition as part of the installation procedure. Issue the
disk command to create the mediafs partitions; issue the mediafs command to maintain these partitions (refer
to Maintaining the Hard Disk Storage for further information on disk partitions). The RealProxy software can
be administered with the RealAdministrator GUI (to access this page, the default username/password is
admin/diamond).
