Supported Software Features for the Cisco uBR7200 Series
COPS TCP Support for the Cisco Cable Modem Termination System
Cisco IOS Release 12.3(13a)BC introduces optimized support for the Common Open Policy Service
(COPS) feature for the Cisco uBR7200 series routers. This feature supports two new configuration
commands for enabling and setting COPS processes. The COPS feature in Cisco 12.3(13a)BC enables
the following COPS functions:
COPS DSCP Marking for the Cisco CMTS
This feature allows you to change the DSCP marking for COPS messages that are transmitted or received
by the Cisco router. Differentiated Services Code Point (DSCP) values are used in Quality of Service
(QoS) configurations on a Cisco router. DSCP summarizes the relationship between DSCP and IP
precedence.
Cisco IOS Release 12.3(13a)BC supports this function with the
configuration mode.
COPS TCP Window Size for the Cisco CMTS
This feature allows you to override the default TCP receive window size that is used by COPS processes.
This setting can be used to prevent the COPS server from sending too much data at one time.
Cisco IOS Release 12.3(13a)BC supports this function with the
global configuration mode.
These two commands affect all TCP connections with all COPS servers.
