In this mode, only one virtual host N port (HBA port) is created per IPS port. All the iSCSI hosts
connecting to that IPS port will be multiplexed using the same virtual host N port (see
This mode simplifies the task of statically binding WWNs. LUN mapping and assignment on the Fibre
Channel storage array must be configured to allow access from the proxy virtual N port's pWWN for all
LUNs used by each iSCSI initiator which connects through this IPS port. The LUN is then assigned to
each iSCSI initiator by configuring iSCSI virtual targets (see the

Proxy initiator mode can be configured on a per IPS port basis, in which case only iSCSI initiators
terminating on that IPS port will be in this mode.
When a IPS port is configured in proxy-initiator mode, Fabric Login (FLOGI) is done via the virtual
iSCSI interface of the IPS port. After the FLOGI is completed, the proxy-initiator virtual N port is
on-line in the Fibre Channel Fabric and virtual N port is registered in the Fibre Channel Name Server.
The IPS module or MPS-14/2 module registers the following entries in the Fibre Channel Name Server:
•
•
•
•
Similar to transparent initiator mode, user can provide a pWWN and nWWN or request a system
assigned WWN for the proxy initiator N port.
To configure the proxy initiator, follow these steps:
Command
Step 1
switch# config terminal
switch(config)#
Step 2
switch(config)# interface iscsi 4/1
switch(config-if)#
