Global ACLs These are applied on server-facing ENode ports.
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-congured ACLs. A user-congured ACL entry cannot deny FCoE and FIP
snooping frames.
The following illustration shows an MXL 10/40GbE switch used as a FIP snooping bridge in a converged Ethernet network. The top-
of-rack (ToR) switch operates as an FCF for FCoE trac. Converged LAN and SAN trac is transmitted between the ToR switch
and an MXL switch. The MXL 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 congure the FIP snooping feature on a switch that functions as a FIP snooping bridge so
that it can perform the following functions:
• Perform FIP snooping (allowing and parsing FIP frames) globally on all VLANs or on a per-VLAN basis.
