transmitted between the ToR switch and an FN IOM switch. The FN IOM switch operates as a lossless FIP
snooping bridge to transparently forward FCoE frames between the ENode servers and the FCF switch.
Figure 35. FIP Snooping on an FN IOM 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:
• 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.
• 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.
