FCoE on the Nexus 7000 also supports a unique capability that enables interfaces to be
shared between two VDCs. This enables the Nexus 7000 to be used in the access layer of
networks where servers connect to the switch and use FCoE. A shared interface enables
FCoE traffic to be segmented into the Storage VDC at the edge of the network. When an
interface is shared between two VDCs, a few rules must be followed:
• Interfaces can be shared only between one Ethernet VDC and one Storage VDC.
• Interfaces to be shared must be configured as 802.1Q trunks in the Ethernet VDC.
• Interfaces may be shared only from the Ethernet VDC that allocated VLANs to the
Storage VDC.
• The Ethernet VDC “owns” the physical interface. If the interface is admin down in the
Ethernet VDC, it will be admin down in the Storage VDC.
• All ports that have a common ASIC must be allocated as shared interfaces. This is
done in groups of two on the F1 modules and groups of four on F2/F2e modules.
