Configuring RoCE Bonding
You can implement RoCE bonding by switching physical ports based on the bonding function
provided by the OS and using the RoCE driver. Multiple physical ports can be bound as a
logical port to implement fault tolerance, bandwidth expansion, and load balancing.

5.1 Overview
The RoCE bonding supports three modes: Active-backup mode1, Balance-XOR mode2, and
802.3ad mode4.
l
Active-backup mode1: Only one device is active. If the active device fails, the other
device becomes active. The MAC address is visible externally. The MAC address of the
bonding in this mode is unique, preventing switch access disorders. This mode provides
only the fault tolerance capability and high availability of network connections, but the
resource utilization is low.

Balance-XOR mode2: Data is transmitted based on the selected hash policy. This mode
provides load balancing and fault tolerance capabilities.
