6.2.1.12. interfaces

6.2.1.12.1. Introduction

The interfaces command of the show subgroup enables displaying the GCap network interfaces:

  • the management interfaces ( gcp0 and gcp1)

  • the detection 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:

  • Status: the configured status of the interface among {Enabled|Disabled}

  • Physical Address: the mac address of the interface

  • Speed: the speed of the interface

  • Type:

    • if it concerns a virtual interface: Virtual

    • if it is a physical interface: the type of cable/sfp connected to the physical port

6.2.1.12.2. Prerequisites

  • User: setup

  • Dependencies: the detection engine must be switched off

6.2.1.12.3. Commands

show interfaces{ |delay|}

6.2.1.12.4. Example of displaying the available capture interfaces

  • Enter the following command.

(gcap-cli) show interfaces

  • Validate.

The system displays the available capture interfaces.

Note

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

If the interfaces are not recognised, the system displays irrelevant information as in the example below:

In this case, the system was unable to associate each of the network interfaces with its name.

Note

Without the interfaces being assigned, access via the SSH connection on the gcpx port does not work.

Connect to the GCap:

  • either by a direct connection (connect directly to the server)

  • or by a HTTP remote connection (iDRAC function for a Dell server)

  • or by a remote connection to the CLI in SSH via the iDRAC interface in serial port redirection mode

To correct this problem, two actions are possible:

6.2.1.12.5. Example of displaying the grace period given to start up the interfaces

  • Enter the following command.

(gcap-cli) show interfaces delay

  • Validate.

The system displays the grace period for starting up the interfaces.
