Reserved VSAN Range and Isolated VSAN Range Guidelines
On an NPV switch with a trunking configuration on any interface, or on a regular switch where the
feature fport_channel_trunk command has been issued to enable the Trunking F PortChannels feature,
follow these configuration guidelines for reserved VSANs and the isolated VSAN:
•
•
•
The following VSAN IDs are assigned in the Fibre Channel Framing and Signaling (FC-FS) interface
standard:
VF_ID Value
00h
001h ... EFFh
F00h ... FEEh
FEFh
FF0h ... FFEh
FFFh
FEFh = 4079
Applying Zone Configurations to VSAN 1
In the setup script, you can configure system default values for the default-zone to be permit or deny,
and you can configure default values for the zone distribution method and for the zone mode.
These default settings are applied when a new VSAN is created. However, the settings will not take effect
on VSAN 1, because it exists prior to running the setup script. Therefore, when you need those settings
for VSAN 1, you must explicitly issue the following commands:

Running Storage Applications on the MSM-18/4
The Cisco MDS 9000 18/4-Port Multiservice Module (MSM-18/4) does not support multiple, concurrent
storage applications. Only one application, such as SME or DMM, can run on the MSM-18/4 at a time.
Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 4.2(1a)

If trunk mode is on for any of the interfaces or NP PortChannel is up, the reserved VSANs are 3040
to 4078, and they are not available for user configuration.
The Exchange Virtual Fabric Protocol (EVFP) isolated VSAN is 4079, and it is not available for user
configuration.
VSAN 4079 will be impacted by an upgrade to NX-OS Release 4.1(3a), depending on whether or
not VSAN 4079 was created prior to the upgrade. See the
section on page 19
for details.
