Chapter 10. Configuring network bridges in the web console
Network bridges are used to connect multiple interfaces to the one subnet with the same range of IP addresses.
Prerequisites
The RHEL 8 web console installed and enabled.
For details, see Installing the web console.
10.1. Configuring a network bridge by using the RHEL web console
Use the RHEL web console to configure a network bridge if you prefer to manage network settings using a web browser-based interface.
Prerequisites
- Two or more physical or virtual network devices are installed on the server.
- To use Ethernet devices as ports of the bridge, the physical or virtual Ethernet devices must be installed on the server.
To use team, bond, or VLAN devices as ports of the bridge, you can either create these devices while you create the bridge or you can create them in advance as described in:
Procedure
-
Select the
Networking
tab in the navigation on the left side of the screen. -
Click Add bridge in the
Interfaces
section. - Enter the name of the bridge device you want to create.
- Select the interfaces that should be ports of the bridge.
Optional: Enable the
Spanning tree protocol (STP)
feature to avoid bridge loops and broadcast radiation.- Click Apply.
By default, the bridge uses a dynamic IP address. If you want to set a static IP address:
-
Click the name of the bridge in the
Interfaces
section. -
Click
Edit
next to the protocol you want to configure. -
Select
Manual
next toAddresses
, and enter the IP address, prefix, and default gateway. -
In the
DNS
section, click the + button, and enter the IP address of the DNS server. Repeat this step to set multiple DNS servers. -
In the
DNS search domains
section, click the + button, and enter the search domain. If the interface requires static routes, configure them in the
Routes
section.- Click Apply
-
Click the name of the bridge in the
Verification
Select the
Networking
tab in the navigation on the left side of the screen, and check if there is incoming and outgoing traffic on the interface:
10.2. Removing interfaces from the bridge using the web console
Network bridges can include multiple interfaces. You can remove them from the bridge. Each removed interface will be automatically changed to the standalone interface.
Learn how to remove a network interface from a software bridge created in the RHEL 8 system.
Prerequisites
- Having a bridge with multiple interfaces in your system.
Procedure
- Log in to the RHEL web console. For details, see Logging in to the web console.
- Open Networking.
- Click the bridge you want to configure.
- In the bridge settings screen, scroll down to the table of ports (interfaces).
- Select an interface and click the - button.
Verification steps
- Go to Networking to check that you can see the interface as a standalone interface in the Interface members table.
10.3. Deleting bridges in the web console
You can delete a software network bridge in the RHEL web console. All network interfaces included in the bridge will be changed automatically to standalone interfaces.
Prerequisites
- Having a bridge in your system.
Procedure
Log in to the RHEL web console.
For details, see Logging in to the web console.
- Open the Networking section.
- Click the bridge you want to configure.
Click Delete.
Verification steps
- Go back to Networking and verify that all the network interfaces are displayed in the Interface members table.
Some interfaces that were previously part of the bridge can become inactive. If necessary, activate them and set network parameters manually.
