Configuring N Port Identifier Virtualization

Configuring N Port Identifier Virtualization

This chapter describes how to configure N Port Identifier Virtualization (NPIV).

This chapter includes the following sections:

Information About N Port Identifier Virtualization

N port identifier virtualization (NPIV) provides a means to assign multiple FC IDs to a single N port. This feature allows multiple applications on the N port to use different identifiers and allows access control, zoning, and port security to be implemented at the application level. The following figure shows an example application using NPIV.

Figure 1. NPIV Example

Enabling N Port Identifier Virtualization

You can enable or disable NPIV on the switch.

Before You Begin

You must globally enable NPIV for all VSANs on the switch to allow the NPIV-enabled applications to use multiple N port identifiers.


Note


All of the N port identifiers are allocated in the same VSAN.


SUMMARY STEPS

    1.    configure terminal

    2.    feature npiv

    3.    no feature npiv


DETAILED STEPS
      Command or Action Purpose
    Step 1 configure terminal


    Example:
    switch# configure terminal
    switch(config)#
     

    Enters configuration mode.

     
    Step 2 feature npiv


    Example:
    switch(config)# feature npiv
     

    Enables NPIV for all VSANs on the switch.

     
    Step 3 no feature npiv


    Example:
    switch(config)# no feature npiv
     

    Disables (default) NPIV on the switch.
