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

The established, precedence, and fragments options are ignored when you apply IPv4-ACLs
–
(containing these options) to Gigabit Ethernet interfaces.
– If an IPv4-ACL rule applies to a preexisting TCP connection, that rule is ignored. For example
if there is an existing TCP connection between A and B, and an IPv4-ACL specifies dropping
all packets whose source is A and destination is B is subsequently applied, it will have no effect.
