What is active-backup bonding Linux?
active-backup or 1 — Sets an active-backup policy for fault tolerance. Transmissions are received and sent out through the first available bonded port interface. Another bonded port interface is only used if the active bonded port interface fails. balance-xor or 2 — Transmissions are based on the selected hash policy.
How do I enable LACP in Linux?
Introduction
- Step 1: Log in with SSH. Log in as root.
- Step 2: Disable NetworkManager.
- Step 3: Configure nameservers.
- Step 4: Load bonding kernel module.
- Step 5: Create bonding interface configuration file.
- Step 6: Update physical interface configuration files.
- Step 8: Reboot.
- Step 9: Check bonding interface status.
What is Linux network bonding?
Network Interface Bonding is a mechanism used in Linux servers which consists of binding more physical network interfaces in order to provide more bandwidth than a single interface can provide or provide link redundancy in case of a cable failure.
What is LACP Linux?
LACP identifies the MAC address of the Ethernet link that has the highest port priority and is of the lowest value, and it assigns that MAC address to the LAG bundle. This bonding mode requires a switch that supports IEEE 802.3ad dynamic links.
How does LACP protocol work?
LACP is compatible with other peers that run the 802.3ad LACP protocol. It automatically binds the member links without manually configuring the LAG, thereby avoiding errors. Tentative sessions are created for all interfaces in a particular VLAN.
Can LACP be active active?
LACP runs on any link that is configured to be in the active state. The port in an active mode also automatically initiates negotiations with other ports by initiating LACP packets. Passive mode—the interface is not in an active negotiating state. LACP runs on any link that is configured in a passive mode.

How do I bond an ip in Linux?
Following the example below will create a NIC Channel Bonding using eth0, eth1 and round-robin policy for fault tolerance and load balancing:
- As root, create a Bond0 Configuration File: # vi /etc/sysconfig/network-scripts/ifcfg-bond0.
- Add the following lines to the Bond0 Configuration File: DEVICE=bond0.
How do I find the bond interface in Linux?
If the physical interfaces are up and the bond interface is showing down, perform the following:
- Verify the bonding status by using the command cat /proc/net/bonding/bond0 .
- Check the LACP parameters from the actor (server self-configuration) device and confirm that they are correct as per the local configuration.
