Appendix A CSG2 Command Reference
idle (CSG2 content)
idle (CSG2 content)
To specify the minimum amount of time that the CSG2 maintains an idle content connection, use the idle
command in CSG2 content configuration mode. To restore the default idle duration value, use the no
form of this command.
idle duration
no idle duration
Syntax Description
Defaults The default idle duration is 300 seconds (5 minutes).
Command Modes CSG2 content configuration
Command History
Usage Guidelines Real Time Streaming Protocol (RTSP) billing in the CSG2 is based on inspection of the RTSP SETUP
and TEARDOWN messages that are exchanged between the subscriber and network. The CSG2 builds
the RTSP call detail record (CDR) immediately after the RTSP TEARDOWN signal if the URL exactly
matches that from the RTSP SETUP signal. Otherwise, the CSG2 builds the CDR after any condition
that causes the flows to be terminated, as when a service_stop is triggered (for example, when the access
network sends a RADIUS Accounting Stop for the subscriber).
For RTSP, do not set the idle timer duration to less than 60 seconds.
When using HTTP as the transport for RTSP, the control connection is used sparingly and might time
out, causing the stream to become unresponsive. This occurs because the subscriber opens two TCP
connections, one for the main content and one for control. The subscriber uses the control connection
sparingly, which can cause the connection to time out. To prevent this problem, ensure that the content
idle timer has a duration of at least 60 seconds (the default setting is 300 seconds). This is not an issue
when using UDP or TCP as the transport.
The CSG2 tracks usage on a per-session basis. User Datagram Protocol (UDP) does not have an
end-of-session indicator and simply idles out. For that reason, for UDP and wireless application
protocol 1.x (WAP 1.x), setting the content idle timer to a low value (for example, 30) allows the CSG2
duration Content idle timer duration in seconds. If no packets are received on a content
connection for more than duration seconds, the CSG2 assumes the connection is idle
and ends the connection.
The range is from 4 to 65535. The default is 300.
Release Modification
12.4(11)MD This command was migrated from CSG1.
Changes from CSG1: The default setting for the duration argument changed from
3600 seconds to 300 seconds.
