Dynamic ACL generation on the switch operating as a FIP snooping bridge function as follows:
Port-based ACLs These 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
These take precedence over user-configured ACLs. A user-configured ACL entry cannot deny FCoE and
FIP snooping frames.
The following illustration shows a switch used as a FIP snooping bridge in a converged Ethernet network. The top-of-rack (ToR)
switch operates as an FCF for FCoE traffic. Converged LAN and SAN traffic is transmitted between the ToR switch and an
S4048ON switch.The switch operates as a lossless FIP snooping bridge to transparently forward FCoE frames between the
ENode servers and the FCF switch.

The following sections describe how to configure the FIP snooping feature on a switch:
Allocate CAM resources for FCoE.
Perform FIP snooping (allowing and parsing FIP frames) globally on all VLANs or on a per-VLAN basis.
To assign a MAC address to an FCoE end-device (server ENode or storage device) after a server successfully logs in,
set the FCoE MAC address prefix (FC-MAP) value an FCF uses. The FC-MAP value is used in the ACLs installed in
bridge-to-bridge links on the switch.
