6.2.2.6. interfaces

6.2.2.6.1. Introduction

The interfaces command of the set subgroup enables the administration of capture interfaces.
Interfaces can be physical or virtual.
Virtual interfaces enable replaying .pcap files directly on the GCap.

Important

Interfaces composing an aggregation of interfaces ("cluster") can neither be enabled nor disabled.

6.2.2.6.2. Prerequisites

User: setup
Dependencies:
- The detection engine must be switched off
- To enable an interface, it must be in the disabled state
- To disable an interface, it must be in the enabled state

6.2.2.6.3. Command

To change the delay before starting up the interfaces: set interfaces delay SECOND.
To enable or disable interfaces: set interfaces {enable|disable} {mon0|mon1|mon2|mon3|monvirt}

6.2.2.6.4. Example to change the interface start-up delay by five seconds

Enter the following command.
```
(gcap-cli) set interfaces delay 5
```
Validate.

6.2.2.6.5. Example of enabling the `mon0` capture interface

Enter the following command.
```
(gcap-cli) set interfaces enable mon0
```
Validate.

Note

If the system displays the following message, Command set interfaces enable monx is not recognised, check whether the monx interface is an aggregation using the show clusters command.

6.2.2.6.6. Example of disabling the `mon1` capture interface

Enter the following command.
```
(gcap-cli) set interfaces disable mon1
```
Validate.

Note

If the system displays the following message, Command set interfaces disable monx is not recognised, check whether the monx interface is an aggregation using the show clusters command.
