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
You must enable FIP snooping on an Aggregator and configure 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:
Global ACLs are applied on server-facing ENode ports.
Port-based ACLs are applied on ports directly connected to an FCF and on server-facing ENode ports.
Port-based ACLs take precedence over global ACLs.
FCoE-generated ACLs take precedence over user-configured ACLs. A user-configured ACL entry
cannot deny FCoE and FIP snooping frames.
The below illustration depicts an Aggregator used as a FIP snooping bridge in a converged Ethernet
network. The ToR switch operates as an FCF for FCoE traffic. Converged LAN and SAN traffic is
transmitted between the ToR switch and an Aggregator. The Aggregator operates as a lossless FIP
snooping bridge to transparently forward FCoE frames between the ENode servers and the FCF switch.
