Administrator Guide
• FIP discovery: FCoE end-devices and FCFs are automatically discovered.
• Initialization: FCoE devices perform fabric login (FLOGI) and fabric discovery (FDISC) to 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 link termination logout
(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 the following port modes:
• ENode mode for server-facing ports
• FCF mode for a trusted port directly connected to an FCF
You must enable FIP snooping on an Aggregator 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 an Aggregator operating as a FIP snooping bridge functions as follows:
