About Vsan Creation; Creating Vsans Statically - Cisco Nexus 5000 Series Configuration Manual

Guidelines and Limitations for VSANs
• 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.
Note A VSAN name must be unique.
• Load-balancing attributes—These attributes indicate the use of the source-destination ID (src-dst-id) or
the originator exchange OX ID (src-dst-ox-id, the default) for load-balancing path selection.
• 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.
• You can create only 14 VSANs in N5672UP-16G, including the default VSAN 1.
• For an NPV switch which is configured for trunking on any interface, or for a regular switch where the
f port-channel-trunk command is issued to enable the Trunking F Port Channels feature, follow these
configuration guidelines for reserved VSANs and isolated 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.

Creating VSANs Statically

You cannot configure any application-specific parameters for a VSAN before creating the 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.
• If the trunk mode is enabled for any of the interfaces, or if the NP port channel is up, the reserved
VSANs range from 3040 to 4078, which are not available for user configuration.
• The Exchange Virtual Fabric Protocol (EVFP) isolated VSAN is 4079, and it is not available for
user configuration.
