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 traffic 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 configured for any of 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 the switch, configure the FIP snooping parameters, and configure CAM
allocation for FCoE (optional in FTOS version 9.1.(0.0)). When you enable FIP snooping, all ports on the
switch by default become ENode ports.
Dynamic ACL generation on the switch operating as a FIP snooping bridge functions as follows:
