displays a VRRP-based high availability FCIP configuration example. This configuration, requires at
least two physical Gigabit Ethernet ports connected to the Ethernet switch on the island where you need
to implement high availability using VRRP.

VRRP-Based High Availability
FC fabric
IP interfaces are in VRRP group
If the active VRRP port fails, the standby VRRP port takes over the VRRP IP address.
When the VRRP switchover happens, the FCIP link automatically disconnects and reconnects.
This configuration has only one FCIP (E)ISL link.

Ethernet PortChannel-Based High Availability
FC fabric
Ethernet ports are
in PortChannel
The Gigabit Ethernet link level redundancy ensures a transparent failover if one of the Gigabit
Ethernet links fails.
Two Gigabit Ethernet ports in one Ethernet PortChannel appears like one logical Gigabit Ethernet
link.
The FCIP link stays up during the failover.
