FIP provides functionality for discovering and logging into an FCF. After discovering and logging in, FIP allows FCoE traffic 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 traffic.
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 FLOGO packet, FSB deletes all existing
sessions from the ENode to the FCF.
