About the Default VSAN

The factory settings for switches in the Cisco 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.
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
Note
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
Note
isolated.
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.
