9.3.1.7. show interfaces

A - Introduction

The `interfaces` command of the `show` sub-group enables displaying the GCap network interfaces:

  • The management and tunnel interfaces

  • The capture interfaces available physically `mon0` to `monx` or virtually `monvirt`

This command can take the keyword `delay` as a parameter to display the grace period granted to the interfaces.
The following information is available with the `show interfaces` command:

  • `Label`: The label name of the interface, `monX` for capture interfaces, `tunnel` for IPSec connections, `management` for SSH connections or SSH and IPSec connections if the interface role is `management-tunnel`, `clusterX` for interfaces in cluster mode.

  • `Name`: the system name of the interface

  • `Role`: The role assigned to the interface, `capture` for capture interfaces,```tunnel``` for IPSec connections, `management` for SSH connections, `management-tunnel` for SSH and IPSec connections, `capture-cluster` for capture interfaces in cluster mode, `inactive for deactivated interfaces.

  • `Capture capability`: if the interface can capture traffic

  • `MTU`: the MTU of the interface

  • `Physical Address`: the MAC address of the interface

  • `Speed`: the interface speed

  • `Type`: the type of cable/sfp connected to the physical port

  • `Vendor ID`: the Vendor ID of the network card

  • `Device ID`: the ID of the network card

  • `PCI bus`: PCI bus number used by the network card

B - Prerequisites

  • User: setup

  • Dependencies: N/A

C - Command

`show interfaces{ |delay|}`

D - Procedure to display the available network interfaces

The command prompt is displayed.

(gcap-cli)

  1. Enter the command

    show interfaces
  2. Validate
    The system displays the available capture interfaces

    image0

    Note

    All existing interfaces are displayed, even those making up an aggregation of interfaces.

E - Procedure to display the grace period given to start up the interfaces

The command prompt is displayed.

(gcap-cli)

  1. Enter the command

    show interfaces delay
  2. Validate
    The system displays the grace period for starting up the interfaces
    NIC startup delay: 10 seconds
