Administering NIC Bonding in KVM on RHEL 9.6

Last Updated : Oct 30, 2026 |
Prolog information
Red Hat Enterprise Linux (RHEL) offers a variety of options and configurations for setting up network bonding. While the Red Hat vendor does not provide a single "best" recommended configuration, it is important to note that for Avaya ASP 130 R7.x, the only tested and supported configuration method is adding a bond with physical interfaces. Be aware that combining bridges, bridges with VLAN tags, or virtual machine interfaces when adding a bond is not supported by Avaya. When applicable to keep a streamlined and consistent behavior the default bridge0 will be the primary reference point for NIC bonding behaviors and expectations.

Note:
This topology includes VLANs to logically segregate different types of traffic over a single network trunk. While VLANs are not required for LACP, their use is recommended when multiple traffic flows share the same link.
