connected to the Ethernet switch on the island where you need to implement high availability using
VRRP.

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 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 appear like one logical Gigabit Ethernet
link.
