408 | FIP Snooping

• Port-based ACLs are applied on all three port modes: on ports directly connected to an FCF,
server-facing ENode ports, and bridge-to-bridge links.
• 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.
Figure 18-2 shows a switch 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 S4810 switch. The switch operates as a lossless FIP snooping bridge to transparently
forward FCoE frames between the ENode servers and the FCF switch.
