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