Configuring and Managing VSANs
all devices in the fabric are considered part of the default VSAN. By default, all ports are assigned to the
default VSAN.
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).
When you configure a port in VSAN 4094 or move a port to VSAN 4094, that port is immediately isolated.
Note
Do not use an isolated VSAN to configure ports.
Caution
Up to 256 VSANs can be configured in a switch. Of these, one is a default VSAN (VSAN 1), and another
Note
is an isolated VSAN (VSAN 4094). User-specified VSAN IDs range from 2 to 4093.

Displaying Isolated VSAN Membership

The show vsan 4094 membership command displays all ports associated with the isolated VSAN.

Operational State of a VSAN

A VSAN is in the operational state if the VSAN is active and at least one port is up. This state indicates that
traffic can pass through this VSAN. This state cannot be configured.

About Static VSAN Deletion

When an active VSAN is deleted, all of its attributes are removed from the running configuration. VSAN-related
information is maintained by the system software as follows:
• VSAN attributes and port membership details are maintained by the VSAN manager. This feature is
affected when you delete a VSAN from the configuration. When a VSAN is deleted, all the ports in that
VSAN are made inactive and the ports are moved to the isolated VSAN. If the same VSAN is recreated,
