Figure 3: VSANS with Zoning, on page 11 shows the possible relationships between VSANs and zones. In
VSAN 2, three zones are defined: zone A, zone B, and zone C. Zone C overlaps both zone A and zone B as
permitted by Fibre Channel standards. In VSAN 7, two zones are defined: zone A and zone D. No zone crosses
the VSAN boundary—they are completely contained within the VSAN. Zone A defined in VSAN 2 is different
and separate from zone A defined in VSAN 7.

VSAN Configuration
VSANs have the following attributes:
• VSAN ID—The VSAN ID identifies the VSAN as the default VSAN (VSAN 1), user-defined VSANs
(VSAN 2 to 4093), and the isolated VSAN (VSAN 4094).
• State—The administrative state of a VSAN can be configured to an active (default) or suspended state.
Once VSANs are created, they may exist in various conditions or states.
• The active state of a VSAN indicates that the VSAN is configured and enabled. By enabling a
VSAN, you activate the services for that VSAN.
• The suspended state of a VSAN indicates that the VSAN is configured but not enabled. If a port is
configured in this VSAN, it is disabled. Use this state to deactivate a VSAN without losing the
VSAN’s configuration. All ports in a suspended VSAN are disabled. By suspending a VSAN, you
can preconfigure all the VSAN parameters for the whole fabric and activate the VSAN immediately.
• VSAN name—This text string identifies the VSAN for management purposes. The name can be from 1
to 32 characters long and it must be unique across all VSANs. By default, the VSAN name is a
concatenation of VSAN and a four-digit string representing the VSAN ID. For example, the default name
for VSAN 3 is VSAN0003.
