Configuring the Dynamic Flow Capture Interface
You specify the interface that interacts with the control sources configured in the same dynamic flow capture group. A Monitoring Services III PIC can belong to only one capture group, and you can configure only one PIC for each group.
To configure a dynamic flow capture interface, include the interfaces statement at the [edit services dynamic-flow-capture] hierarchy level:
You specify dynamic flow capture interfaces using the dfc- identifier at the [edit interfaces] hierarchy level. Three logical units are required on each dynamic flow capture interface, numbered 0, 1, and 2. You cannot configure any other logical interfaces.
- unit 0 processes control protocol requests and responses.
- unit 1 receives monitored data.
- unit 2 transmits the matched packets to the destination address.
The following example shows the configuration necessary to set up a dynamic flow capture interface:
# control source to correspond with the monitoring station.}}}unit 1 { # Receives data packets on this logical interface.family inet; }unit 2 { # Sends copies of matched packets from this logical interface.family inet; }
In addition, you must configure the dynamic flow capture application to run on the DFC PIC in the correct chassis location. The following example shows this configuration at the [edit chassis] hierarchy level:
For more information on configuring chassis properties, see the Junos System Basics Configuration Guide.
