VNMC
VNMC is a virtual appliance, based on Red Hat Enterprise Linux (RHEL), that provides centralized device and security policy management of the Cisco Virtual Security Gateway (VSG) for the Cisco Nexus 1000V Series switch. Designed for multitenant operation, VNMC provides seamless, scalable, and automation-centric management for virtualized data center and cloud environments. With a web-based GUI, CLI, and XML APIs, VNMC allows you to manage VSGs that are deployed throughout the data center from a centralized location.
Multitenancy refers to the architectural principle, where a single instance of the software runs on a Software-as-a-Service (SaaS) server, serving multiple client organizations or tenants. Multitenancy is contrasted with a multi-instance architecture, where separate software instances are set up for different client organizations. With a multitenant architecture, a software application is designed to virtually partition data and configurations, so that each tenant works with a customized virtual application instance.
VNMC is built on an information model-driven architecture, where each managed device is represented by its subcomponents. This architecture enables VNMC to provide greater agility and simplification for securing multitenant infrastructure.
VNMC communicates with vCenter, VSM, and VSG over a management VLAN.

This section contains information about the VNMC CLIs.
This section includes the following topics:
Overview of the VNMC CLIs
An important component of the VNMC is the CLI. With it, you can perform the following tasks:
•Restore VNMC to full state of the VNMC without having to reinstall.
•Collect the technical support data and copy it to a file.
•Change the hostname.
•Change the management interface IP settings.
•Configure VNMC device profiles.
•Create VNMC system policies.
•Create backups and import/export services.
VNMC contains six sub-CLIs. You use all six sub-CLIs to manage VNMC. The CLIs are as follows:
•Management controller—This is the default CLI. The command prompt is host-name#. Use this CLI to perform the following tasks:
host-name#

VNMC CLIs Basic Commands
The basic commands for the VNMC CLIs are as follows:
•commit-buffer—Saves the configuration.
commit-buffer can be used with the optional keyword verify-only. When you execute commit-buffer verify-only the configuration is not saved, just verified.
•connect—Connects to other CLIs.
•discard-buffer—Deletes the configuration.
•enter—Creates an object and places you in a mode.
•exit—Exits modes, CLIs, and the default CLI.
•scope—Places you in a mode.
•show—Displays information.
•top—Places you in management controller mode.
•where—Shows you where you are at in the VNMC CLI.
•?—Displays the commands available in the mode.
•>—Redirects show commands to a file.
•>>—Redirect show commands to a file in append mode.
•|—Pipes cshow ommand output to a filter.
