350 | FCoE Transit

Dynamic ACL generation on the switch operating as a FIP snooping bridge functions as follows:
• 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 16-2. FIP Snooping on an S5000 Switch
Figure 16-2 shows an S5000 switch enabled for FCoE transit and 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 S5000 switch. The switch operates as a lossless
FIP snooping bridge to transparently forward FCoE frames between the ENode servers and the FCF
switch.
