Limitations and Restrictions
For configuration information, refer to the “Configuring Trunking” section in the Cisco MDS 9000
NX-OS Interfaces Configuration Guide.
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 used to enable the Trunking F port channels feature,
follow these configuration guidelines for reserved VSANs and the isolated VSAN:
• If trunk mode is on for any of the interfaces or NP port channel 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.
The following VSAN IDs are assigned in the Fibre Channel Framing and Signaling (FC-FS) interface
standard:
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 use the following commands:
• zone default-zone permit vsan 1
• zoneset distribute full vsan 1
• zone mode enhanced vsan 1
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.
