Users Guide
FIP enables FCoE devices to discover one another, initialize and maintain virtual links over an Ethernet network, and access storage devices
in a storage area network (SAN). FIP satises the Fibre Channel requirement for point-to-point connections by creating a unique virtual link
for each connection between an FCoE end-device and an FCF via a transit switch.
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.
Table 24. 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.
