Enable FIP snooping on the switch, configure the FIP snooping parameters, and configure CAM allocation for FCoE. When you enable FIP
snooping, all ports on the switch by default become ENode ports.
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 core switch. The
switch operates as a lossless FIP snooping bridge to transparently forward FCoE frames between the ENode servers and the FCF switch.
Figure 38. FIP Snooping on an Core Switch
The following sections describe how to configure the FIP snooping feature on a switch that functions as a FIP snooping bridge so that it
can perform the following functions:
• Allocate CAM resources for FCoE.
• Perform FIP snooping (allowing and parsing FIP frames) globally on all VLANs or on a per-VLAN basis.
