Youcannot create VLANs with IDs from 3968 to 4047. This range of VLAN IDs is reserved.
VLANsin the LAN cloud and FCoEVLANs in the SAN cloudmust have different IDs. Using the same
IDfor aVLAN and an FCoE VLAN in a VSAN results in a critical fault and traffic disruption for all
vNICsand uplink ports using that VLAN. Ethernet traffic is dropped on any VLAN which has an ID that
overlapswith an FCoEVLAN ID.

afterthe object has beensaved.
VLANName/Prefix field
Youcan choose one of the following:
Common/Global—TheVLANs apply to both fabrics and use the
sameconfiguration parameters in both cases
FabricA—The VLANs only apply to fabric A.
FabricB—The VLAN only apply to fabric B.
BothFabrics Configured Differently—The VLANs apply to
bothfabrics but you can specify different VLAN IDs for each
fabric.
Forupstream disjointL2 networks, we recommendthat you choose
Common/Globalto create VLANs that apply to both fabrics.
