Configuring Gigabit Ethernet High Availability

Virtual Router Redundancy Protocol (VRRP) and Ethernet PortChannels are two Gigabit Ethernet
features that provide high availability for iSCSI and FCIP services.

VRRP for iSCSI and FCIP Services

VRRP provides a redundant alternate path to the Gigabit Ethernet port for iSCSI and FCIP services.
VRRP provides IP address failover protection to an alternate Gigabit Ethernet interface so the IP address
is always available (see

You can configure no more than seven VRRP groups, both IPv4 and IPv6, on a Gigabit Ethernet
