Monitor or Change Interface Connections

The Interface section, on the Networking page of the web console, displays host network information about each configured network interface. Selecting an interface name provides details about the interface, and configurable properties that Cockpit administrators can choose to change. These properties include IP address, MAC address, connection state at reboot, and the interface status state (active or inactive).

What Do You Need?

• The Cockpit web console must be installed and accessible.

  For details, see these topics: Install and Enable Cockpit and Log in to the Cockpit Web Console.

• The cockpit-networkmanager package is installed. Typically, this package is installed by default. For package installation details, see Install and Manage Add-on Applications.
• Administrator privileges.

Steps

Use the Cockpit web console, follow these steps to monitor the host interface network traffic, and to change their configuration.

1. In the Networking page, navigate to the Interface panel and view the following information about each host interface.
   • Interface name, IP address, and inbound and outbound traffic load.
   • At the top of the page, a set line charts appear. These line charts depict the total traffic load seen across all host interfaces.

     Click the drop-down menu to change the interval values appearing on the chart axis labels. By default, each chart depicts the data in 5-minute increments.

2. Click the name of an interface and perform any of the following tasks:
   • Monitor interface performance or review device related details. For example, the following interface-specific information appears.
     • Real-time line charts displaying the inbound and outbound traffic load. Click the drop-down menu to change the interval values on the line chart axis labels. By default, each chart depicts the data in 1-hour increments.
     • Connection name, device manufacturer model name, device status, and carrier speed.
     • Configured property values for: device MAC address, IP4 address, IP6 address, MTU packet or frame size, and the current toggle switch setting depicting the current interface state (inactive or active).
   • Edit the interface configuration properties. Choose to change any of the following properties:

     Property	Description
     MAC address Note: This address appears as a 12 digit hexadecimal number with a colon or hyphen separating every two digits (2C:54:91:28:C7:E3).	Click the mac-address link, edit the mac-address shown by selecting an option from the drop-down text box, then click Save.
     Automatic Connection	Activate or deactivate the network interface connection after a reboot. Do one of the following: Select the checkbox to automatically activate the connection after a reboot. Clear the checkbox to automatically deactivate the connection after a reboot.
     IPv4 or IPv6	Click edit to view and change the IPv4 or IPv6 configuration properties. Choose to set automatic generated IP property values or specify user-defined IP property values.
     MTU	Click edit to change the interface maximum transfer unit size (MTU). Choose to set an automatic generated MTU value or specify a user-defined MTU property value.
     Toggle switch	Click the toggle switch to control the network interface state (inactive or active). By default, the toggle switch appears blue with a check mark to indicate that the state is active. Clearing the toggle switch deactivates the state.
