This document describes the procedure for getting started with virtual device contexts (VDCs) on an NX-OS device.

This publication includes the following topics:

•Introduction to VDCs

•Creating and Initializing a VDC

•Obtaining Documentation and Submitting a Service Request

Introduction to VDCs

VDCs partition a single physical device into multiple logical devices that provides fault isolation, management isolation, address allocation isolation, service differentiation domains, and adaptive resource management. You can manage a VDC instance within a physical device independently. Each VDC appears as a unique device to the connected users. A VDC runs as a separate logical entity within the physical device, maintains its own unique set of running software processes, has its own configuration, and can be managed by a separate administrator.

For more information about working with VDCs using the NX-OS software, see the Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide, Release 4.1.

Creating and Initializing a VDC

This section describes how to create and initialize a VDC.

To create and initialize a VDC, follow these steps:

---

Step 1 Log in to the default VDC with a username that has the network-admin role.

Step 2 Enter configuration mode and create the VDC using the default settings.

switch# configure terminal

switch(config)# vdc MyVDC

Note:  VDC creation is a time consuming process, please wait until the command completes

switch(config-vdc)#

Step 3 (Optional) Allocate interfaces to the VDC.

---

Note When you allocate an interface to a VDC, the interface configuration is lost.

---

switch(config-vdc)# show vdc membership

vdc_id: 1 vdc_name: switch interfaces:

Ethernet2/1           Ethernet2/2           Ethernet2/3

        Ethernet2/4           Ethernet2/5           Ethernet2/6

        Ethernet2/7           Ethernet2/8           Ethernet2/9

        Ethernet2/10          Ethernet2/11          Ethernet2/12

        Ethernet2/13          Ethernet2/14          Ethernet2/15

        Ethernet2/16          Ethernet2/17          Ethernet2/18

        Ethernet2/19          Ethernet2/20          Ethernet2/21

        Ethernet2/22          Ethernet2/23          Ethernet2/24

        Ethernet2/25          Ethernet2/26          Ethernet2/27

        Ethernet2/28          Ethernet2/29          Ethernet2/30

        Ethernet2/31          Ethernet2/32          Ethernet2/33

        Ethernet2/34          Ethernet2/35          Ethernet2/36

        Ethernet2/37          Ethernet2/38          Ethernet2/39

        Ethernet2/40          Ethernet2/41          Ethernet2/42

        Ethernet2/43          Ethernet2/44          Ethernet2/45

        Ethernet2/46          Ethernet2/47          Ethernet2/48

switch(config-vdc)# allocate interface ethernet 2/11-14

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

Step 4 Verify the VDC configuration.

switch(config-vdc)# show vdc MyVDC

vdc_id  vdc_name                          state               mac

------  --------                          -----               ----------

2       MyVDC                             active              00:00:00:00:00:00

Step 5 Switch to the new VDC and enter the VDC admin user account password.

switch(config-vdc)# switchto vdc MyVDC

         ---- System Admin Account Setup ----

  Enter the password for "admin": <password>

  Confirm the password for "admin": <password>

Step 6 (Optional) Execute the setup script for your VDC.

---

Note You can bypass the setup script and execute it later from within the VDC using the setup command.

---

         ---- Basic System Configuration Dialog VDC: 3 ----

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 Nexus 7000 Series devices promptly with your

supplier. Failure to register may affect response times for initial

service calls. Cisco Nexus 7000 Series 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

Step 7 When you finish the setup script, or bypass it, you enter your new VDC.
