To enable dynamic mapping of Fibre Channel targets into iSCSI, follow these steps:
Command
Step 1
switch# config terminal
switch(config)#
Step 2
switch(config)# iscsi import target fc

Static Mapping

You can manually (statically) create an iSCSI target by assigning a user-defined unique iSCSI node name
to it. The iSCSI qualified name is restricted to a minimum length of 16 characters and a maximum of
223 characters. A statically mapped iSCSI target can either map the whole Fibre Channel target port (all
LUNs in the target port mapped to the iSCSI target), or it can contain one or more LUs from a Fibre
Channel target port (see

Advertising Static iSCSI Targets
You can limit the Gigabit Ethernet interfaces through which static iSCSI targets are advertised. By
default iSCSI targets are advertised on all Gigabit Ethernet interfaces, subinterfaces, PortChannel
interfaces, and PortChannel subinterfaces.
To configure a specific interface that should advertise the iSCSI virtual target, follow these steps:
Command
Step 1
switch(config-iscsi-tgt)# advertise
interface GigabitEthernet 2/5
switch(config-iscsi-tgt)# no advertise
interface GigabitEthernet 2/5

interfaces, issue the command for each
interface.
Removes this interface from the list of interfaces from
which this target is advertised.
