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.

FIP Snooping on Ethernet Bridges
In a converged Ethernet network, intermediate Ethernet bridges can snoop on FIP packets during the login process on an FCF. Then,
using ACLs, a transit bridge can permit only authorized FCoE trac to be transmitted between an FCoE end-device and an FCF. An
Ethernet bridge that provides these functions is called a FIP snooping bridge (FSB).
On a FIP snooping bridge, ACLs are created dynamically as FIP login frames are processed. The ACLs are installed on switch ports
congured for ENode mode for server-facing ports and FCF mode for a trusted port directly connected to an FCF.
Enable FIP snooping on the switch and congure the FIP snooping parameters. When you enable FIP snooping, all ports on the
switch by default become ENode ports.
Dynamic ACL generation on the MXL switch operating as a FIP snooping bridge function as follows:
