On the Cisco Nexus 7000 Series 32-port, 10-Gbps Ethernet module N7K-F132XP-15, you must allocate the interfaces on your physical device in the specified combination. This module has 16 port groups that consist of 2 ports each (2 interfaces x 16 port groups = 32 interfaces). Interfaces that belong to the same port group must belong to the same VDC

Configuration Example for Ethernet VDC Creation and Initialization: 

Beginning with the Cisco NX-OS Release 5.2(1), you can run FCoE on the Cisco Nexus Series 7000 devices. You must create a separate storage VDC to run FCoE. See the Cisco NX-OS FCoE Configuration Guide for Cisco Nexus 7000 and Cisco MDS 9500 for an example of configuring a storage VDC.

This example shows how to create and initialize a VDC:

switch# config t
switch(config)# vdc test
switch(config-vdc)# allocate interface ethernet 1/18
Moving ports will cause all config associated to them in source vdc to be removed. Are you sure you want to move the ports? [yes] yes
switch(config-vdc)# exit
switch(config)# switchto vdc test

---- System Admin Account Setup ----
Do you want to enforce secure password standard (yes/no) [y]: y
Enter the password for "admin":<password>
Confirm the password for "admin":<password>

---- Basic System Configuration Dialog ----
This setup utility will guide you through the basic configuration of
the system. Setup configures only enough connectivity for management
of the system.
Please register Cisco Nexus7000 Family devices promptly with your
supplier. Failure to register may affect response times for initial
service calls. Nexus7000 devices must be registered to receive
entitled support services.
Press Enter at anytime to skip a dialog. Use ctrl-c at anytime
to skip the remaining dialogs.
Would you like to enter the basic configuration dialog (yes/no): yes
Create another login account (yes/no) [n]: n
Configure read-only SNMP community string (yes/no) [n]: n
Configure read-write SNMP community string (yes/no) [n]: n
Enter the switch name : Test
Continue with Out-of-band (mgmt0) management configuration? (yes/no) [y]:

Mgmt0 IPv4 address : 10.10.5.5
Mgmt0 IPv4 netmask : 255.255.254.0
Configure the default gateway? (yes/no) [y]: y
IPv4 address of the default gateway : 10.10.5.1
Configure advanced IP options? (yes/no) [n]:
Enable the telnet service? (yes/no) [y]:
Enable the ssh service? (yes/no) [n]: y
Type of ssh key you would like to generate (dsa/rsa/rsa1) : rsa
Number of key bits <768-2048> : 768
Configure the ntp server? (yes/no) [n]:
Configure default switchport interface state (shut/noshut) [shut]:
Configure default switchport trunk mode (on/off/auto) [on]:
The following configuration will be applied:
switchname Test
interface mgmt0
ip address 10.10.5.5 255.255.254.0
no shutdown
exit
vrf context management
ip route 0.0.0.0/0 10.10.5.1
exit
telnet server enable
ssh key rsa 768 force
ssh server enable
system default switchport shutdown
system default switchport trunk mode on
Would you like to edit the configuration? (yes/no) [n]:
Use this configuration and save it? (yes/no) [y]:
