Enabling the FCoE Transit Feature
The following sections describe how to enable FCoE transit.
NOTE: FCoE transit is disabled by default. To enable this feature, you must follow the Configuring
FIP Snooping.
As soon as you enable the FCoE transit feature on a switch-bridge, existing VLAN-specific and FIP
snooping configurations are applied. The FCoE database is populated when the switch connects to a
converged network adapter (CNA) or FCF port and compatible DCB configurations are synchronized. By
default, all FCoE and FIP frames are dropped unless specifically permitted by existing FIP snooping-
generated ACLs. You can reconfigure any of the FIP snooping settings.
If you disable FCoE transit, FIP and FCoE traffic are handled as normal Ethernet frames and no FIP
snooping ACLs are generated. The VLAN-specific and FIP snooping configuration is disabled and stored
until you re-enable FCoE transit and the configurations are re-applied.
Enable FIP Snooping on VLANs
You can enable FIP snooping globally on a switch on all VLANs or on a specified VLAN.
When you enable FIP snooping on VLANs:
• FIP frames are allowed to pass through the switch on the enabled VLANs and are processed to
generate FIP snooping ACLs.
• FCoE traffic is allowed on VLANs only after a successful virtual-link initialization (fabric login FLOGI)
between an ENode and an FCF. All other FCoE traffic is dropped.
• You must configure at least one interface for FCF (FIP snooping bridge-bridge) mode on a FIP
snooping-enabled VLAN.
