7750 SR OS Router Configuration Guide Page 315Filter Sampling

Within a filter entry, you can specify that traffic matching the associated IP filter entry is sampled.

if the IP interface is set to cflowd ip-filter mode. Enabling filter-sample enables the cflowd tool.

Use the following CLI syntax to enable filter sampling:

CLI Syntax: config>filter# ip-filter filter-id

entry entry-id time-range time-range-name

filter-sample

interface-disable-sample

The following displays the configuration command usage to enable filter sampling in an existing

filter configuration:

Example: config>filter# ip-filter 11

config>filter>ip-filter# entry 10

config>filter>ip-filter>entry# filter-sample

config>filter>ip-filter>entry# interface-disable-sample

config>filter>ip-filter>entry# exit

The following example displays the IP filter entry configuration.
