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. 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.
• To provide more port security on ports that are directly connected to an FCF and have links to other FIP snooping bridges,
set the FCF or Bridge-to-Bridge Port modes.
• To ensure that they are operationally active, check FIP snooping-enabled VLANs.
• Process FIP VLAN discovery requests and responses, advertisements, solicitations, FLOGI/FDISC requests and responses,
FLOGO requests and responses, keep-alive packets, and clear virtual-link messages.
