If the FN IOM Switch functions in the NPIV mode and you attempt to set the uplink port to be an FCF or a bridge port, a warning message
displays and the settings are not saved.
Operation of the NPIV Proxy Gateway
The NPIV application on the FC Flex IO module manages the FC functionalities congured in Dell Networking OS. After the FC link comes
up, the gateway sends the initial FLOGI request to the connected switch using the switch and port WWN methods. After a successful
login, the NPIV gateway sends a notication to inform the CNA that the FCF available to log in. The source address of the FIP
advertisement and FIP discovery advertisement response contain the MAC address of the FC Flex IO module port. Depending on the
number of login sessions on a particular FCF, the NPIV gateway can load-balance the login sessions from ENodes.
The NPIV application performs the FLOGI to FDISC conversion and sends the new FC frame on the associated FC ports. After the external
switch responds to the FLOGI request, the NPIV gateway establishes the NPIV session and sends the frame to the FIP application. The FIP
application establishes virtual links to convert FCoE FLOGI accept messages into FIP FLOGI accept messages. The corresponding ACL for
the accept message is then applied. If a FIP timeout from ENode or VN_PORT occurs, the NPIV application performs the FC fabric logout
to the external FC switch. The NPIV application manages the sessions between the FCoE and the FC domain.
Installing and Conguring the Switch
