displays a Virtual Router Redundancy Protocol (VRRP)-based high availability FCIP
VRRP-Based High Availability
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.

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
