You specify the interface that interacts with the control sources configured in the same 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 DFC PIC interface, include the interfaces statement at the [edit services dynamic-flow-capture capture-group client-name] hierarchy level:
-
interfaces interface-name;
You specify DFC interfaces using the dfc- identifier at the [edit interfaces] hierarchy level. You must specify three logical units on each DFC PIC interface, numbered 0, 1, and 2. You cannot configure any other logical interfaces.
The following example shows the configuration necessary to set up a DFC PIC interface:
- [edit interfaces dfc-0/0/0]
- unit 0 {
-
- family inet {
-
- address 10.1.0.0/32 { # DFC PIC address
- destination 10.36.100.1; # DFC PIC address used by
- # the control source to correspond with the
- # monitoring platform
- }
- }
- }
- unit 1 { # receive data packets on this logical interface
- family inet;
- }
- unit 2 { # send out copies of matched packets on 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:
- fpc 0 {
-
- pic 0 {
- monitoring-services application dynamic-flow-capture;
- }
- }
