NCS Delivery Modes

Cisco NCS comes preinstalled on a physical appliance with various performance characteristics. The NCS software runs on either a dedicated Cisco Prime Network Control System appliance or on a VMware server. The NCS software image does not support the installation of any other packages or applications on this dedicated platform. The inherent scalability of NCS allows you to add appliances to a deployment and increase performance and resiliency.

NCS is delivered in two modes, the Physical Appliance and Virtual Appliance. This section contains the following topics:

Physical Appliance, page 2-2

Virtual Appliance, page 2-2

Operating Systems Requirements, page 2-3

Client Requirements, page 2-4

Prerequisites, page 2-4

Physical Appliance

The Physical Appliance is a dual Intel 2.40GHz Xeon E5620 quad core processor, with 16 GB RAM, and four hard drives running in a RAID level 5 configuration. The appliance will run the latest 64bit Red Hat Linux Operating System.

The Physical Appliance supports up to 15000 Cisco Aironet lightweight access points, 5000 standalone access points, 5000 switches and 1200 Cisco wireless LAN controllers.


Note To receive the expected results with NCS, you should run on High performance Physical appliance with built-in redundancy for hard disks, power supplies and internal cooling fans.


For more information on the Physical Appliance, see Cisco Prime Network Control System Getting Started Guide, Release 1.0.

Virtual Appliance

NCS is also offered as a Virtual Appliance, to help support lower level deployments. Cisco NCS can be run on a workstation or a server, and access points can be distributed unevenly across controllers.

The NCS Virtual Appliance software is distributed as an Open Virtualization Archive (OVA) file. There are three recommended levels of NCS distribution with different resources, and numbers of devices supported.

This section contains the following topics:

Virtual Appliance for Large Deployment, page 2-2

Virtual Appliance for Medium Deployment, page 2-3

Virtual Appliance for Small Deployment, page 2-3


Note You can deploy the OVA file directly from the vSphere Client; you do not need to extract the archive before performing the deployment.


You can install NCS Virtual Appliance using any of the method for deploying an OVF supported by the VMware environment. Before starting, make sure that the NCS Virtual Appliance distribution archive is in a location that is accessible to the computer on which you are running the vSphere Client.

Deploying the NCS Virtual Appliance

This section describes how to deploy NCS Virtual Appliance both from the vSphere Client using the Deploy OVF Wizard or from the command line.(VMware vSphere Client, a Windows application for managing and configuring the vCenter Server) This section contains the following topics:

Deploying the NCS Virtual Appliance from the VMware vSphere Client, page 2-6

Deploying NCS Virtual Appliance using the Command Line Client, page 2-9

Deploying the NCS Virtual Appliance from the VMware vSphere Client

NCS Virtual Image is packaged as an OVA file. An OVF is a collection of items in a single archive. In the vSphere Client, you can use the Deploy OVF Wizard to create a virtual machine, running the NCS Virtual Appliance application, as described in this section.


Note While the following procedure provides a general guideline for how to deploy NCS Virtual Appliance, the exact steps that you need to perform may vary depending on the characteristics of your VMware environment and setup.


To deploy the NCS Virtual Appliance, follow these steps:


Step 1 From the VMware vSphere Client main menu, choose File > Deploy OVF Template. The Deploy OVF Template Source window appears: (See Figure 2-1)

Figure 2-1 Deploy OVF Template window

Step 2 Choose Deploy from file and choose the OVA file that contains the NCS Virtual Appliance distribution.

Step 3 Click Next. The OVF Template Details window appears. VMware ESX/ESXi reads the OVA attributes. The details include the product you are installing, the size of the OVA file (download size), and the amount of disk space that needs to be available for the virtual machine (size on disk).

Step 4 Verify the OVF Template details and click Next. The Name and Location window appears (See Figure 2-2).

Figure 2-2 Name and Location window

Step 5 Either keep the default name for the VM to be deployed in the Name text box or provide a new one and click Next. This name value is used to identify the new virtual machine in the VMware infrastructure so you should use any name that distinguishes this particular VM in your environment.The Host / Cluster window appears (see Figure 2-3).

Figure 2-3 Host/Cluster Window

Step 6 Choose the destination host or HA cluster on which you want to deploy the NCS VM and click Next. The Resource Pool window appears.

Step 7 If you have more than one resource pool in your target host environment, choose the resource pool to use for the deployment and click Next. The Ready to Complete window appears.

Step 8 Review the settings shown for your deployment and, if needed, click the Back button to modify any of the settings shown.

Step 9 Click Finish to complete the deployment. A message notifies you when the installation completes and you can see the NCS Appliance in your inventory.

Step 10 Click Close to dismiss the Deployment Completed Successfully dialog box.


Configuring the Basic Settings for NCS Virtual Appliance

You have completed deploying (installing) NCS Virtual Appliance on a new virtual machine. A node for the virtual machine now appears in the resource tree in the VMware vSphere Client window. Deploying the OVF template creates a new virtual machine in vCenter with the NCS Virtual Appliance application and related resources already installed on it. After deployment, you need to configure basic settings for NCS Virtual Appliance. To start the NCS setup, follow these steps:


Step 1 In the vSphere Client, click the NCS Virtual Appliance node in the resource tree. The virtual machine node should appear in the Hosts and Clusters tree below the host, cluster, or resource pool to which you deployed NCS Virtual Appliance.

Step 2 On the Getting Started tab, click the Power on the virtual machine link under Basic Tasks. The Recent Tasks pane at the bottom of the vSphere Client pane indicates the status of the task associated with powering on the virtual machine. After the virtual machine successfully starts, the status column for the task displays Completed.

Step 3 Click the Console tab, within the console pane to make the console prompt active for keyboard input.


Now you need to set up the virtual appliance, as described in Setting Up NCS, page 2-9 section.

Deploying NCS Virtual Appliance using the Command Line Client

This section describes how to deploy the NCS Virtual Appliance from the command line. As an alternative to using the vSphere Client to deploy the NCS OVA distribution, you can use the VMware OVF Tool, which is a command-line client.

To deploy an OVA with the VMware OVF Tool, use the ovftool command, which takes the name of the OVA file to be deployed and the target location as arguments, as in the following example:

ovftool NCS-VA-X.X.X-large.ova vi://my.vmware-host.example.com/ 
 
   

In this case, the OVA file to be deployed is NCS-VA-X.X.X-large.ova and the target ESX host is my.vmware-host.example.com. For complete documentation on the VMware OVF Tool, see the VMware vSphere 4.0 Documentation.

Setting Up NCS

This section describes how to configure the initial settings of the NCS Virtual Appliance.


Note These steps need to be performed only once, upon first installation of NCS Virtual Appliance.


To configure the basic network and login settings for the NCS Virtual Appliance system, follow the below steps. When the steps are completed, the NCS Virtual Appliance is accessible over the network.


Note Once you put the NCS Image DVD in the physical appliance for reinstallation, you will get the same console prompt. Use the following steps to reinstall NCS for the physical appliance.



Step 1 At the login Prompt, enter setup.

localhost.localdomain login: setup 

The NCS configuration script starts. The script takes you through the initial configuration steps for NCS Virtual Appliance. In the first sequence of steps, you configure network settings.

Step 2 As prompted, enter the following settings:

a. Hostname for the virtual appliance.

b. IP address for the virtual appliance.

c. IP default subnet mask for the IP address entered.

d. IP address of the default gateway for the network environment in which you are creating the virtual machine.

e. Default DNS domain for the target environment.

f. IP address or hostname of the primary IP nameserver in the network.

g. At the Add/Edit another nameserver prompt, you can enter y (yes) to add additional nameservers, if desired. Otherwise, press Enter to continue.

h. NTP server location (or accept the default by pressing Enter). At the Add/Edit secondary NTP server prompt, you can enter y (yes) to add another NTP server. Otherwise, enter n (no) to continue.

Step 3 Enter the username for the user account used to access the Cisco NCS system running on the virtual machine. The default username is admin, but you can change this to another username by typing it here.

Step 4 Enter the password for NCS. The password must be at least eight characters and must include both lowercase and uppercase letters and at least one number. It cannot include the username or default Cisco passwords. After you enter the password, the script verifies the network settings you configured. For instance, it attempts to reach the default gateway that you have configured.

After verifying the network settings, the script starts the NCS installation processes. This process can take several minutes, during which there is no screen feedback. When finished, the following banner appears on the screen:

=== Initial Setup for Application: NCS === 

After this banner, it starts with database scripts and reboots the server as shown in the console:

Running database cloning script...
logger: invalid option -- l
usage: logger [-is] [-f file] [-p pri] [-t tag] [-u socket] [ message ... ]
Running database creation script...
logger: invalid option -- l
usage: logger [-is] [-f file] [-p pri] [-t tag] [-u socket] [ message ... ]
Setting Timezone, temporary workaround for DB...
Generating configuration...
Rebooting...

Note If you are installaing a physical appliance, remove the ISO DVD from the DVD tray.


Step 5 Log in as admin and enter the admin password.

Step 6 Exit the console using the exit command.


Starting the NCS Server

This section provides instructions to start NCS on either a physical appliance or virtual appliance.


Note To check the status of NCS at any time, follow the instructions in the "Verifying the Status of NCS" section on page 4-6.


To start the NCS server, follow these steps:


Step 1 Once you have setup NCS, rebooted the server and login as admin.

Step 2 Enter the following command to start the NCS Server.

ncs start

Logging into the NCS User Interface

To log into the NCS user interface through a web browser, follow these steps:


Step 1 Launch Internet Explorer 7.0 or later or Mozilla Firefox 3.6 or later on a different computer than the one on which you installed and started NCS.


Note When you use Firefox 3.x to log in and access NCS for the first time, the Firefox web browser displays a warning that the site is untrustable. When Firefox displays this warning, follow the prompts to add a security exception and download the self-signed certificate from the NCS server. After you complete this procedure, Firefox accepts the NCS server as a trusted site both now and during all future login attempts.


Step 2 In the address line of browser, enter https://ncs-ip-address, where ncs-ip-address is the IP address of the server on which you installed and started NCS. The NCS user interface displays the Login page.

Step 3 Enter your username. The default username is root.

Step 4 Enter the root password you created during setup.


Note If any licensing problems occur, a message appears in an alert box. If you have an evaluation license, the number of days until the license expires is shown. You are also alerted to any expired licenses. You have the option to go directly to the licensing page to address these problems.


Step 5 Click Login to log into NCS. The NCS user interface is now active and available for use. The NCS home page appears. The NCS home page enables you to choose the information that you want to see. You can organize the information in user-defined tabs called dashboards. The default view comes with default dashboards and pre-selected dashlets for each, and you can arrange them as you like. You can predefine what appears on the home page by choosing the monitoring dashlets that are critical for your network. For example, you may want different monitoring dashlets for a mesh network so that you can create a customized mesh dashboard.


Note If the database or Apache web server does not start, check the launchout.txt file in Linux. You will see a generic "failed to start database" or "failed to start the Apache web server" message.



Note When an upgrade occurs, the user-defined tabs arranged by the previous user in the previous version are maintained. Therefore, the latest dashlets may not show. Look at the Edit dashboard link to find what new dashlets are added.


The home page provides a summary of the Cisco Unified Network Solution, including coverage areas, the most recently detected rogue access points, access point operational data, reported coverage holes, and client distribution over time. Figure 2-4 shows a typical NCS home page.

By default, you should see six dashboards on the NCS home page: General, Client, Security, Mesh, CleanAir and ContextAware dashboards.


Note When you use NCS for the first time, the network summary pages show that the Controllers, Coverage Areas, Most Recent Rogue APs, Top 5 APs, and Most Recent Coverage Holes databases are empty. It also shows that no client devices are connected to the system. After you configure the NCS database with one or more controllers, the NCS home page provides updated information.


Figure 2-4 NCS Home Page

To exit the NCS user interface, close the browser page or click Log Out in the upper-right corner of the page. Exiting an NCS user interface session does not shut down NCS on the server.

When a system administrator stops the NCS server during your NCS session, your session ends, and the web browser displays the message: "The page cannot be displayed." Your session does not reassociate to NCS when the server restarts. You must restart the NCS session.

Applying the NCS Software License

This section describes how to apply a license to NCS. Before starting, make sure that you have already acquired the license from the Cisco License Center and put it in a location that is accessible by the network from NCS. To add a new NCS license file, follow these steps:


Step 1 In the Administrator menu, choose License Center > Files > NCS Files page, and click Add.

Step 2 In the Add a License File dialog box, enter or browse to the applicable license file.

Step 3 Once displayed in the License File text box, click Upload.


To add a new license, see "Managing Licenses" section on page 15-123.

Understanding NCS Home Page

The NCS home page:

enables the administrator to create and configure Cisco Unified Network Solution coverage area layouts, configure system operating parameters, monitor real-time Cisco Unified Network Solution operations, and perform troubleshooting tasks using an HTTPS web browser page.

enables the administrator to create, modify, and delete user accounts; change passwords; assign permissions; and schedule periodic maintenance tasks. The administrator creates new usernames and passwords and assigns them to predefined permissions groups.

allows the administrator to perform all necessary network administration tasks from one page. The NCS home page, is the landing page, displaying real-time monitoring and troubleshooting data. The navigation tabs and menus at the top of the page provide point-and-click access to all other administration features.

The NCS user interface provides an integrated network administration console from which you can manage various devices and services. These include wired and wireless devices and clients. The services may include authentication, authorization, profiler, location and mobility services as well as monitoring, troubleshooting, and reporting. All of these devices and services can be managed from a single console called the Cisco Prime NCS home page.

Dashboards

The NCS dashboards consist of dashlets and graphs that provide a visual overview of network health and security. The Dashboard elements visually convey complex information in a simplified format. This display allows you to quickly analyze the data and drill down for in-depth information if needed. Dashlets utilize a variety of elements to display data, including pie-charts, sparklines, stack bars, and metric meters.

The fundamental purpose of a dashboard is to provide an at-a-glance view of the most important parts of NCS. A quick scan of the dashboard should let you know if anything needs attention. Dashboard generally provides the status and alerts, monitoring and reporting information. Dashboards contain several dashlets, which are UI containers that display a variety of widgets, such as text, form elements, tables, charts, tabs, and nested content modules.

The dashboard displays the current status which reflects the status and usage of the network, like client distribution. The dashboard also displays the trend which reflects the usage and status over time which is from data collected over time, like client count.

Figure 2-5 Dashboards


Note You must have Adobe Flash Player installed to view the dashlets on the NCS dashboard.


The six NCS dashboards are described in this section. This section contains the following topics:

General Dashboard, page 2-15

Client Dashboard, page 2-16

Security Dashboard, page 2-17

Mesh Dashboard, page 2-18

CleanAir Dashboard, page 2-18

Context Aware Dashboard, page 2-21

You can customize the predefined set of dashlets depending on your network management needs. You can organize the information in user-defined dashboards. The default view comes with default dashboards and pre-selected dashlets for each.


NoteThe label "Edited" next to the dashlet heading indicates that the dashlet has been customized. If you reset to the default settings, the Edited label is cleared. Hover your mouse cursor over the label see the edited information.

When an upgrade occurs, the arrangement of dashlets in a previous version is maintained. Because of this, dashlets or features added in a new release are not displayed. Click the Manage Dashboards link to discover new dashlets.

The horizontal and vertical scrollbars are visible if you zoom the dashlets. Reset the zoom level back to zero, or no zoom for viewing the dashlets without the scrollbars.
