2.2.4. Overview of managing the capture interfaces

Important

Concept of role and label is introduced in the release 2.5.4.0.

The monitoring interfaces on GCap perform the `capture` role and are, by default, four in number.

These interfaces receive the flows from the TAPs on the specified interfaces labeled:

• `mon0` for the first TAP

• `mon1` for the second TAP

• `mon2` for the third TAP

• `mon3` for the fourth TAP

For more information regarding the capture interfaces, refer to Capture interfaces.

Note

The number of capture interfaces varies depending on the specifications of each model.

In some special cases, it is possible to use GCaps with eight interfaces instead of four.

In addition, there is also a virtual capture interface labeled `monvirt` enabling `.pcap` file replay directly on the GCap.

In order for the GCap to capture the flow, one or more interfaces must be activated.
