Managing the failover and failback policies
ENABLING THE FAILOVER POLICY
A switch in Access Gateway mode supports automatic N_Port failover to other N_Ports connected
to the same fabric. When a port is first configured as an N_Port, the failover policy is enabled by
default.
If the N_Port goes offline, the F_Ports mapped to that N_Port are automatically failed over to other
online N_Ports connected to the same fabric. If there are multiple online N_Ports connected to the
same fabric, the mapped F_Ports are distributed evenly between the N_Ports.
Failover generates an error message.
To enable failover
1. Connect and log in to the switch.

ENABLING THE FAILBACK POLICY
A switch in Access Gateway mode supports automatic F_Port failback to N_Ports when that port
comes back online. By default the failback policy is enabled.
When an N_Port with an enabled failback policy comes back online, the F_Ports that were originally
mapped to it are automatically rerouted back to the N_Port.
