When you configure a port in VSAN 4094 or move a port to VSAN 4094, that port is immediately
Do not use an isolated VSAN to configure ports.
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.
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:
OL-16184-01, Cisco MDS SAN-OS Release 3.x
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, the ports do not automatically get assigned to that VSAN. You must explicitly reconfigure
the port VSAN membership (see
