Cisco Nexus 5000 Series Switch CLI Software Configuration Guide (OL-16597-01, July 2009)

Enabling N Port Identifier Virtualization
To enable or disable NPIV on the switch, perform this task:
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.
All of the N port identifiers are allocated in the same VSAN.Note
Procedure
PurposeCommand or Action
Enters configuration mode.switch# configuration terminal
Step 1
Enables NPIV for all VSANs on the switch.switch(config)# npiv enable
Step 2
Disables (default) NPIV on the switch.switch(config)# no npiv enable
Step 3
Verifying Fibre Channel Interfaces
Verifying SFP Transmitter Types
The SPF transmitter type can be displayed for a physical Fibre Channel interface (but not for a virtual Fibre
Channel).
The small form-factor pluggable (SFP) hardware transmitters are identified by their acronyms when displayed
in the show interface brief command. If the related SFP has a Cisco-assigned extended ID, then the show
interface and show interface brief commands display the ID instead of the transmitter type. The show
interface transceiver command and the show interface fc slot/port transceiver command display both values
for Cisco supported SFPs.
Verifying Interface Information
The show interface command displays interface configurations. If no arguments are provided, this command
displays the information for all the configured interfaces in the switch.
You can also specify arguments (a range of interfaces or multiple, specified interfaces) to display interface
information. You can specify a range of interfaces by entering a command with the following example format:
interface fc2/1 - 4 , fc3/2 - 3
