Concept Guide
FIP provides functionality for discovering and logging into an FCF. After discovering and logging in, FIP allows FCoE trac to be sent and 
received between FCoE end-devices (ENodes) and the FCF. FIP uses its own EtherType and frame format. The following illustration shows 
the communication that occurs between an ENode server and an FCoE switch (FCF).
The following table lists the FIP functions.

FIP Function Description
FIP VLAN discovery FCoE devices (ENodes) discover the FCoE VLANs on which to 
transmit and receive FIP and FCoE trac.
FIP discovery FCoE end-devices and FCFs are automatically discovered.
Initialization FCoE devices learn ENodes from the FLOGI and FDISC to allow 
immediate login and create a virtual link with an FCoE switch.
Maintenance A valid virtual link between an FCoE device and an FCoE switch is 
maintained and the LOGO functions properly.
Logout On receiving a FLOGI packet, FSB deletes all existing sessions from 
the ENode to the FCF.
