Default VSANs

The factory settings for Cisco SAN switches 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.
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.

Isolated VSANs

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).
Note When you configure a port in VSAN 4094 or move a port to VSAN 4094, that port is immediately isolated.
Do not use an isolated VSAN to configure ports.
Caution
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.

Displaying Isolated VSAN Membership

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