The differences between the configurations of these two switches are the IP addresses,
and the designation of the first switch as the master of the active-active configuration.

SING MANUAL FAIL-BACK
In an active-active configuration, fail-back is the action of releasing the virtual servers
that are assigned to a failed switch when that switch becomes operational again. By
default, fail-back occurs automatically. If the minor disruption of fail-back makes
automatic fail-back undesirable, you can enable manual fail-back. With manual
fail-back, fail-back occurs only when the operator enters the fail-back command.
To enable manual fail-back, use the following command:
enable slb failover manual-failback
To execute a manual fail-back, use the following command:
configure slb failover failback-now
