DescriptionName
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 recommend that you choose
Common/Globalto create VLANs that apply to both fabrics.
Configurationoptions
Tocreate one VLAN, enter a single numeric ID. To create multiple
VLANs,enter individual IDs or ranges of IDs separated by commas.
AVLAN ID can:
•Bebetween 1 and 3967
•Bebetween 4048 and 4093
•Overlapwith other VLANIDs alreadydefined on the system
Forexample, to create six VLANs with the IDs 4, 22, 40, 41, 42, and
43,you would enter 4, 22, 40-43.
Youcannot create VLANs with IDs from 3968 to 4047.
Thisrange of VLAN IDs is reserved.
VLANsin the LAN cloud and FCoE VLANs in the SAN
cloudmust have different IDs. Using the same ID for a
VLANand an FCoE VLAN in a VSAN results in a critical
faultand traffic disruption for all vNICs and uplink ports
usingthat VLAN. Ethernet traffic is dropped on any VLAN
whichhas an ID that overlaps with an FCoE VLAN ID.
Important
VLANIDs field
Whetherthis VLAN issubdivided intoprivate or secondaryVLANs.
Thiscan be one of the following:
•None—ThisVLAN does not have any secondary or private
VLANs.
•Primary—ThisVLAN can have one or more secondary VLANs,
asshown in the Secondary VLANs area.
•Isolated—Thisis a private VLAN. The primary VLAN with which
itis associated is shown in the Primary VLAN drop-down list.
SharingType field
Ifthe Sharing Type field is set to Isolated, this is the primary VLAN
associatedwith this privateVLAN.
