Fibre Channel Interface Overview
See Chapter 5, “Configuring Fibre Channel Interfaces,” for more information about configuring the
SN 5428-2 for FC fabric zoning.
Fibre Channel Interface Overview
The SN 5428-2 has an integrated switch component with Fibre Channel interfaces that support the
following port types: E_Port, F_Port, FL_Port, G_Port, GL_Port, TL_Port, and donor port.
The SN 5428-2 FC interfaces support GS-3 management server commands. This allows management of
the SN 5428-2 integrated switch component through the Fibre Channel interfaces (in-band
management). See the interface fc? ms-enable command in Chapter 12, “Command Line Interface
Reference,” for more information about enabling the FC interfaces for GS-3 commands.
See Chapter 5, “Configuring Fibre Channel Interfaces,” for more information about configuring FC
ports.
Gigabit Ethernet Interface Overview
Each of the two 1-Gigabit Ethernet interfaces on the SN 5428-2 (GE 1 and GE 2) provide the following
capabilities:
• Multiple IP addresses per SCSI routing instance—allows IP hosts to connect to SCSI routing
instances via one or more IP addresses. Each Gigabit Ethernet interface can be configured with up
to 12 unique IP addresses, which provides a maximum of 24 unique IP addresses per SN 5428-2
Storage Router. If VLAN access is used, the maximum number of unique IP addresses per Gigabit
Ethernet interface increases to 16. This provides a maximum of 32 unique IP addresses per
SN 5428-2 Storage Router when configured with VLAN.
• Assignment of a secondary interface per SCSI routing instance—allows the same IP address to be
assigned to each Gigabit Ethernet interface; one interface is assigned as primary and one interface
is assigned as secondary. If the primary Gigabit Ethernet interface loses connection to the host and
if the secondary connection is assigned and still connected, the IP address moves to the secondary
Gigabit Ethernet interface, which then becomes active.
• Assignment as an interface to an FCIP peer—allows assignment of an IP address as a primary
Gigabit Ethernet interface between an FCIP instance and an FCIP peer. Each SN 5428-2 can be
configured with up to two FCIP instances, and each FCIP instance can be configured with one peer,
for a maximum of two FCIP peers per SN 5428-2 Storage Router when configured for FCIP.
• Assignment of a secondary interface per FCIP instance—allows the same IP address to be assigned
to each Gigabit Ethernet interface configured for an FCIP instance; one interface is assigned as
primary and one interface is assigned as secondary. If the primary interface loses connection to the
network and remains down for two seconds, the IP address moves to the secondary Gigabit Ethernet
interface, which then becomes active.
• Assignment as a management IP address—allows each Gigabit Ethernet interface to have one IP
address assigned per logical interface, as a management interface. This IP address is in addition to
any multiple IP address(es) per SCSI routing instance or FCIP instance assigned.
• Assignment of a secondary management IP address—allows the same IP address to be assigned to
each Gigabit Ethernet interface configured as a management interface; one interface is assigned as
primary and one interface is assigned as secondary. If connection to the primary Gigabit Ethernet
