Chapter 32 Configuring Fibre Channel Interfaces
Verifying Fibre Channel Interfaces
To enable or disable NPIV on the switch, perform this task:
Verifying Fibre Channel Interfaces
The following topics describe the commands for displaying Fibre Channel interfaces:
• Verifying SFP Transmitter Types, page 32-15
• Verifying Interface Information, page 32-15
• Verifying BB_Credit Information, page 32-17
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
The following example shows how to display all interfaces:
switch# show interface
fc3/1 is up
...
fc3/3 is up
...
Ethernet1/3 is up
...
mgmt0 is up
...
vethernet1/1 is up
...
vfc 1 is up
...
Command Purpose
Step 1
switch# configuration terminal
Enters configuration mode.
Step 2
switch(config)# npiv enable
Enables NPIV for all VSANs on the switch.
Step 3
switch(config)# no npiv enable
Disables (default) NPIV on the switch.
