• 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 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 the following port modes:
• ENode mode for server-facing ports
• FCF mode for a trusted port directly connected to an FCF
