Chapter 31. Layer 2 Failover

© Copyright Lenovo 2018
The primary application for Layer 2 Failover is to support Network Adapter
Teaming. With Network Adapter Teaming, all the NICs on each server share the
same IP address, and are configured into a team. One NIC is the primary link, and
the other is a standby link.For more details, refer to the documentation for your
Ethernet adapter.
Note: Only two links per server blade can be used for Layer 2 LAG Failover (one
primary and one backup). Network Adapter Teaming allows only one backup NIC
for each server blade.
