Policy based caching

Enabling passive FTP caching
There is no specific CLI command to enable passive FTP caching. To enable passive CLI caching,
configure “port ftp” within a cache-server configuration, as shown in the following.
ServerIronADX(config)# server cache-name CacheServer6
ServerIronADX(config-rs-CacheServer6)# port ftp
Whether the data channel is in active mode or passive mode depends on the operation of the FTP
Client and Server. If they support passive mode, the ServerIron ADX can automatically adapt to it
for data channel traffic.
Streaming media support
TCS can be used with streaming media content. The RTSP, MMS, and Real streaming media
protocols are supported. The source NAT and destination NAT features are applied correctly to
streams using these protocols, both for the parent TCP connection as well as the actual data
stream.
NOTE
RTSP SLB and source NAT are not supported if Darwin Streaming server is used.
To configure TCS for streaming media content, specify a streaming media port (RTSP, PNM, or
MMS) as part of the definition of the cache server and configure an ip policy statement for the
specified port.
For example, to configure TCS for the RTSP protocol, enter commands such as the following.
ServerIronADX(config)# server cache-name CacheServer1 192.168.1.101
ServerIronADX(config-rs-CacheServer1)# port rtsp
ServerIronADX(config-rs-CacheServer1)# exit
ServerIronADX(config)# ip policy 1 cache tcp rtsp global
If you use TCS with MMS (TCP port 1755 with random UDP ports) or PNM (TCP port 7070), you
must specify port 0 in the ip policy command, since the command accepts TCP or UDP port
numbers no higher than 1023. For example,
ServerIronADX
(config)# server cache-name CacheServer1 192.168.1.101
ServerIronADX(config-rs-CacheServer1)# port mms
ServerIronADX(config-rs-CacheServer1)# port pnm
ServerIronADX(config-rs-CacheServer1)# exit
ServerIronADX(config)# ip policy 1 cache tcp 0 global
ServerIronADX(config)# ip policy 2 cache udp 0 global
NOTE
Streaming media protocols are not supported for IPv6 traffic of TCS.
Policy based caching
Policy based caching allows configuration of a separate set of filters for each cache-group. Users
can use access-lists to define a set of filters and apply these to different cache groups.
To configure the enhanced policy-based caching features, follow the steps below.
