Cisco Nexus 7000 Series NX-OS Virtual Device Context Quick Start, Release 4.2

---

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

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 the Cisco NX-OS software, see the Cisco Nexus 7000 Series NX-OS Virtual Device Context Configuration Guide, Release 4.2.

Creating and Initializing a VDC

This section describes how to create and initialize a VDC.

Procedure

---

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: Creating VDC, one moment please ... switch(config-vdc)#
Step 3	(Optional) Allocate interfaces to the VDC. 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 2/11-1 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 Note    When you allocate an interface to a VDC, the interface configuration is lost.
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 ---- Do you want to enforce secure password standard (yes/no) [y]: y Enter the password for "admin": Confirm the password for "admin":
Step 6	(Optional) Execute the setup script for your VDC. ---- Basic System Configuration Dialog VDC: 2 ---- 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 Please register Cisco Nexus7000 Family devices promptly with your 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): Note    You can bypass the setup script and execute it later from within the VDC using the setup command.
Step 7	When you finish the setup script, or bypass it, you enter your new VDC.
