cops tcp window-size
cops tcp window-size
To override the default TCP receive window size on the Cisco CMTS, use the cops tcp window-size
command in global configuration mode. This setting allows you to prevent the COPS server from
sending too much data at one time. To return the TCP window size to a default setting of 4K, use the no
form of this command.
cops tcp window-size bytes
no cops tcp window-size
Syntax Description
Defaults The default COPS TCP window size is 4000 bytes.
Usage Guidelines This command does not affect existing connections to COPS servers. Once you issue this command, this
function is supported only for new connections after that point in time.
Examples The following example configures the TCP window size to be 64000 bytes.
Router(config)# cops tcp window-size 64000
The following example illustrates online help for this command:
Router(config)# cops tcp window-size ?
<516-65535> Size in bytes
Additional COPS Information
Cisco 12.3(13a)BC also supports Access Control Lists (ACLs) for use with COPS. Refer to the “Access
Control List Support for COPS Intercept” section on page1-73.
