How To Remove The Bond0 Interface In Ubuntu 20.4.Network bonding (also called “NIC teaming”) is a method for combining multiple network interfaces to form a single, logical network interface for increased bandwidth, fault tolerance, or both. In Ubuntu, the bonding configuration is stored in the network configuration files. If you want to remove a bond (e.g., bond0), you need to modify the network configuration.In this guide, we’ll show you how to remove the bond0 interface in Ubuntu. We’ll use the Netplan configuration for Ubuntu 20.4 and later. Step 1: Locate the Netplan Configuration FileNetplan is the default network configuration tool in Ubuntu 18.04 and later versions. First, locate the Netplan configuration file, which is typically found in the /etc/netplan/ directory. The file should have a .yaml extension, for example:/etc/netplan/01-netcfg.yamlThe name of the file might be different on your system. Step 2: Edit the Netplan Configuration FileOpen the Netplan configuration file using a text editor like nano:sudo nano /etc/netplan/01-netcfg.yamlLocate the bond0 interface configuration within the file. It should look similar to the following:bonds: bond0: interfaces: - eth0 - eth1 parameters: mode: balance-rrRemove the entire bond0 configuration block, including the bond0: line and all nested lines under it. Step 3: Reconfigure the Network InterfacesAfter removing the bond0 configuration, you may need to reconfigure the individual network interfaces that were part of the bond (e.g., eth0, eth1). You can configure them as separate interfaces or as part of a new bond.For example, to configure eth0 with a static IP address, add the following configuration to the Netplan file:network: version: 2 renderer: networkd ethernets: eth0: dhcp4: no addresses: - XX.XX.XX.XX/27 gateway4: XX.XX.XX.XX nameservers: addresses: - 8.8.8.8 - 8.8.4.4Adjust the IP addresses, gateway, and nameservers according to your network requirements. Step 4: Apply the New ConfigurationAfter editing the Netplan configuration file, save the changes and exit the text editor. Then, apply the new network configuration using the following command:sudo netplan applyThis command will apply the changes and restart the networking service. The bond0 interface should now be removed, and the other network interfaces should be configured according to the new settings. ConclusionIn this guide, we’ve shown you how to remove the bond0 network interface in Ubuntu using the Netplan configuration tool. Make sure to configure the individual network interfaces that were part of the bond, according to your network requirements.
