Cisco DCNM Virtual Device Context Quick Start

Cisco DCNM Virtual Device Context Quick Start

This document describes the procedure for getting started with virtual device contexts (VDCs) on a Cisco NX-OS device using Cisco Data Center Network Manager (DCNM).

Introduction to VDCs

VDCs partition a single physical device into multiple logical devices that provide 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 Cisco DCNM, see the .

Creating and Discovering a VDC

This section describes how to create and discover a VDC.

Procedure
Step 1   From the Feature Selector pane, choose Virtual Devices.
Step 2   From the Summary pane, click a physical device.
Step 3   From the menu bar, choose Virtual Devices > Create VDC to display the VDC General Parameters dialog box.
Step 4   In the Name field, enter the VDC name and click Next.

The Interface Membership dialog box appears

Step 5   (Optional) Choose the interfaces that you want to allocate to the VDC.
Note   

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

Step 6   Click Next.
Note   

Cisco DCNM uses the default template resource limits.

The Resource Limit dialog box appears.

Step 7   Click Next.

The Authentication dialog box appears.

Step 8   In the Password field, enter the admin user password.
Step 9   In the Confirm Password field, reenter the admin user password and click Next.

The Management of VDC dialog box appears.

Step 10   In the Management Interface area, enter the IPv4 or IPv6 address information.
Step 11   In the SSH area, click the down arrows and choose the SSH key type and SSH key length.
Step 12   In the Default Gateway area, enter the default IPv4 or IPv6 gateway address.
Step 13   In the Discover the VDC area, uncheck the Discover the VDC check box to prevent automatic discovery.
Step 14   Click Finish.
Note   

Creating a VDC can take a few minutes depending on the amount of resources that the device must reserve for the VDC.

Step 15   From the menu bar, choose File > Deploy to apply your changes to the device.
Step 16   From the Feature Selector pane, choose DCNM Server Administration > Devices and Credentials.
Step 17   From the menu bar, choose Devices and Credentials > New Device.

A new line appears in the Devices list.

Step 18   Click the cell under IP Address in the new line and enter the IP address of the VDC to discover.
Step 19   Double click the cell under User Credentials in the new line and click the down arrow to display the user credentials dialog. Enter the user credentials information and click OK.
Step 20   From the menu bar, choose Devices and Credentials > Discover.
