Network Bonding Modes
Swarm supports the following network port bonding modes (as supported by the Linux kernel):
...
Bonding mode 6 (balance-alb) is only supported when using a single peer switch. For the requirements requirement of using multiple switch chassis to provide switch layer redundancy, configure Swarm to use bonding mode 1 (active-backup). Choose You can also choose to use bonding mode 4 (802.3ad) with further planning and testing. Bonding Note that bonding mode 1 (active-backup) is advised for “out of the box” multi-switch and multi-chassis link aggregation (MLAG) configurations, whereas bonding mode 4 (802.3ad) needs additional configuration on the switch side to function. Since failover and traffic balancing with MLAG is proprietary to switch vendors, it is necessary to review switch capability to determine the appropriate bonding mode for MLAG (i.e., bonding mode 1 or 4 i.e. active-backup or 802.3ad).
...
PXE passthrough behavior is important in either an L2 or L3 MLAG configuration. Configuring nodes for network (PXE) boot when 802.3ad and MLAG are in place is difficult to use can be difficult, so planning and testing is critical for such network configurations. Vendor implementation Note that vendor implementations of PXE passthrough for MLAG behaves can differ and may behave inconsistently, therefore , active-backup bonding mode is strongly advised in this scenario.
