Reserved VSAN Range and Isolated VSAN Range Guidelines

Note A VSAN name must be unique.

Note
OX ID based load balancing of IVR traffic from IVR- enabled switches is not supported on Generation 1
switching modules. OX ID based load balancing of IVR traffic from a non-IVR MDS switch should work.
Generation 2 switching modules support OX ID based load balancing of IVR traffic from IVR-enabled
switches.
This section describes how to create and configure VSANs and includes the following topics:
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 f
port-channel-trunk command is issued 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
• The Exchange Virtual Fabric Protocol (EVFP) isolated VSAN is 4079, and it is not available for user

VSAN Creation

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.

Creating VSANs

To create VSANs, follow these steps:
Step 1 switch# config terminal
Enters configuration mode.
Step 2
switch(config)# vsan database
switch(config-vsan-db)#
Configures the database for a VSAN. Application specific VSAN parameters cannot be configured from this prompt.
