> # Tuning the FCIP Link

> ## Detailed Steps

> To tune the required FCIP link, follow these steps:

> 1. Configure the nWWN for the virtual N ports on the switch.
> 2. Enable iSCSI on the interfaces on which you want to create the N ports.
> 3. Configure the virtual N ports on either side of the FCIP link.
> 4. Ensure that the virtual N ports are not visible to real initiators in the SAN. You can use zoning (see the Fabric Configuration Guide, Cisco DCNM for SAN) to segregate the real initiators. Ensure that the zoning configuration is set up to allow the virtual N-ports to communicate with each other.
> 5. Start the SCSI read and write I/Os.
> 6. Add more N ports (as required) to other Gigabit Ethernet ports in the switch to obtain maximum throughput. One scenario that may require additional N ports is if you use FCIP PortChannels.
