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 Conguring FIP
Snooping.
As soon as you enable the FCoE transit feature on a switch-bridge, existing VLAN-specic and FIP snooping congurations are applied.
The FCoE database is populated when the switch connects to a converged network adapter (CNA) or FCF port and compatible DCB
congurations are synchronized. By default, all FCoE and FIP frames are dropped unless specically permitted by existing FIP snooping-
generated ACLs. You can recongure any of the FIP snooping settings.
If you disable FCoE transit, FIP and FCoE trac are handled as normal Ethernet frames and no FIP snooping ACLs are generated. The
VLAN-specic and FIP snooping conguration is disabled and stored until you re-enable FCoE transit and the congurations are re-applied.
Enable FIP Snooping on VLANs
You can enable FIP snooping globally on a switch on all VLANs or on a specied 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 trac is allowed on VLANs only after a successful virtual-link initialization (fabric login FLOGI) between an ENode and an FCF. All
other FCoE trac is dropped.
• You must congure at least one interface for FCF (FIP snooping bridge-bridge) mode on a FIP snooping-enabled VLAN.
• On an S5000 NPIV proxy gateway:
• A maximum of 12 VLANs are supported for FIP snooping.
• The maximum number of FCFs supported on a FIP snooping-enabled VLAN is 12.
• In NPIV mode, FIP Snooping does not work when the default VLAN is other then VLAN1.
• On an S5000 switch not congured as an NPIV proxy gateway:
• A maximum of eight VLANs are supported for FIP snooping.
• The maximum number of FCFs supported on a FIP snooping-enabled VLAN is 12.
NOTE
: When you enable FCoE transit, FIP solicitation responses from an FCF may be forwarded on an FCoE VLAN to multiple
ENodes.
Congure the FC-MAP Value
You can globally congure the FC-MAP on all or individual FCoE VLANs to authorize FCoE trac.
to check the FC-MAP value for the MAC address assigned to ENodes in incoming FCoE frames, use the congured FC-MAP value. If the
FC-MAP value does not match, FCoE frames are dropped. A session between an ENode and an FCF is established by the switch-bridge
only when the FC-MAP value on the FCF matches the FC-MAP value on the FIP snooping bridge.
