Configuring VSANs
About Port VSAN Membership
Port VSAN membership on the switch is assigned on a port-by-port basis. By default each port belongs
to the default VSAN. You can assign VSAN membership to ports using one of two methods:
• Statically—Assigning VSANs to ports.
See the “Assigning Static Port VSAN Membership” section on page 15-8.
• Dynamically—Assigning VSANs based on the device WWN. This method is referred to as dynamic
port VSAN membership (DPVM). Nexus 5000 Series switches do not support DPVM.
VSAN trunking ports have an associated list of VSANs that are part of an allowed list (see Chapter 13,
“Configuring VSAN Trunking”).
Assigning Static Port VSAN Membership
To statically assign VSAN membership for an interface using Fabric Manager, perform this task:
Step 1 In the Physical Attributes pane, expand Switches > Interfaces and then choose FC Physical.
You see the interface configuration in the Information pane.
Step 2 Choose the General tab.
You see the Fibre Channel general physical information. Enter the new VSAN in the PortVSAN field.
Step 3 Click Apply Changes to save these changes, or click Undo Changes to discard any unsaved changes.
About the Default VSAN
The factory settings for switches in the Nexus 5000 Series have only the default VSAN 1 enabled. We
recommend that you do not use VSAN 1 as your production environment VSAN. If no VSANs are
configured, all devices in the fabric are considered part of the default VSAN. By default, all ports are
assigned to the default VSAN.
Note VSAN 1 cannot be deleted, but it can be suspended.
Note Up to 256 VSANs can be configured in a switch. Of these, one is a default VSAN (VSAN 1), and another
is an isolated VSAN (VSAN 4094). User-specified VSAN IDs range from 2 to 4093.
About the Isolated VSAN
VSAN 4094 is an isolated VSAN. When a VSAN is deleted, all nontrunking ports are transferred to the
isolated VSAN to avoid an implicit transfer of ports to the default VSAN or to another configured
VSAN. This action ensures that all ports in the deleted VSAN become isolated (disabled).
