Cisco Prime Network Registrar Jumpstart 9.1.1 Quick Start Guide
Introduction
The Cisco Prime Network Registrar Jumpstart product is a complete solution for using the Cisco Prime Network Registrar application to manage DHCP, DNS, and Caching DNS servers. It includes the following components:
■
Cisco Prime Network Registrar 9.1.1 application software
■Linux CentOS 7.4 Operating System
These components are integrated together into a single flexible and easy to use appliance (see Cisco Prime Network Registrar Jumpstart Configuration).
Figure 1 Cisco Prime Network Registrar Jumpstart Configuration
Cisco Prime Network Registrar Jumpstart Configuration shows the three primary layers in the Cisco Prime Network Registrar Jumpstart appliance. Each of these layers has its own capabilities. Each of these layers can be controlled independently as well as remotely, and each requires its own independent connection to the network. Thus, three unique IP addresses are required.
You may only need to connect to the Cisco Prime Network Registrar Web UI to perform IP address management tasks, but you may also need to connect to one of the other layers to perform system management or troubleshooting tasks related to the appliance.
You can connect to each layer as described below:
■Connecting to Virtual Appliance (Open Virtual Appliance) Layer—You can connect to the Cisco Prime Network Registrar application layer using the web browser. Use http:// vaip :8080 for local and http:// vaip :8090, where vaip is the virtual appliance IP address (which is also the IP address of the Linux Operating System). For a secure connection to the Cisco Prime Network Registrar Web UI, use https:// vaip :8443.
To access the Cisco Prime Network Registrar Command Line Interface (CLI), you can use an SSH connection to the virtual appliance IP address using ssh -l root vaip.
You can manage the Linux OS by connecting to it using ssh -l root vaip. There is no Windows system installed on the Cisco Prime Network Registrar virtual appliance, but the standard Linux commands necessary to manage a networking application are all present on the Linux OS.
■Connecting to ESXi Hypervisor Layer—Connect to the ESXi hypervisor, identified by the IP address esxip (or its DNS name), using the web browser. esxip is the IP address designated to the ESXi hypervisor.
■Connecting to Cisco Integrated Management Controller (CIMC) UCS Management Console—This allows you to configure and manage the ESXi layer. You can connect to the CIMC by using a browser using https:// ucsip /. ucsip is the IP address assigned to the Jumpstart. After you log in to CIMC, you can start the KVM console to get access to the ESXi configuration screen and manage hardware (power, temperature, fan RPM).
This guide contains the following sections:

■ Configuring Cisco Prime Network Registrar Virtual Appliance
Configuring Cisco Prime Network Registrar Jumpstart
To configure the Cisco Prime Network Registrar Jumpstart:
1. Configure the UCS CIMC Network Connection. To configure this, follow the steps in the Connecting and Powering On the Server (Standalone Mode) chapter of the enclosed Cisco UCS C220 Server Installation and Service Guide or you can see the document available online at: https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/c/hw/C220/install/C220.html
You have to configure NIC Mode as None in the Connecting and Powering On (Standalone Mode) procedure.
The CIMC gives you insight into the hardware as well as support for a virtual KVM console allowing remote management of the ESXi layer. For details on CIMC, see the Cisco UCS C-Series Servers Integrated Management Controller GUI Configuration Guide available online at: https://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/c/sw/gui/config/guide/3_1/b_Cisco_UCS_C-series_GUI_Configuration_Guide_31/b_Cisco_UCS_C-series_GUI_Configuration_Guide_31_preface_00.html
Configuring Network Information for ESXi
After configuring the network information for the UCS CIMC console, use the virtual KVM console that the CIMC console provides to configure the network information for the ESXi hypervisor.
1. Use a browser to connect to the IP address of the CIMC console.
2. Log in to the CIMC console.
Note: The default username is admin and default password is password, but you should change the password at your earliest convenience.
3. On the Chassis Summary page, click Launch KVM. Choose Java or HTML. You will be asked to approve the running of the application, as this operation downloads code to run on your system. After some delay, the KVM Console window is displayed.
Note: If login fails, it may be either that someone else already has a virtual KVM console already active for this UCS C220 server or that your browser is not configured to run Java Web Start.
The initial screen on the KVM console displays VMware ESXi 6.5.0.
4. Press F2 to customize the system.
Note: The virtual KVM console needs to capture the mouse to accept input. It may be necessary on some systems to use the mouse to select the Single Cursor option from the Tools menu of the KVM Console window. If nothing happens when you press F2, select the Session Options from the Tools menu and click OK. Usually this causes the mouse to be captured, and then the functions keys will make it through to the console. If you want the mouse back, you can press F12.
5. Press F2 again to view the login window.
6. Log in to the host. The default username is root and the password is password.
Select the Configure Password option and reconfigure the root password after you log in.
7. Using the arrow keys, select the Configure Management Network option and press Enter.
Configuring IP

g. Press Enter to accept the IP Configuration updates.
Note: If you want to use IPv6 with Cisco Prime Network Registrar, use the arrow keys to select IPv6 Configuration and enter the information requested on that screen.
Configuring DNS Servers
9. To configure the DNS Servers:
a. Use the arrow keys to select DNS Configuration and press Enter.
b. Use the arrow keys to select Primary DNS Server and enter the IP address of the primary DNS server.
c. Use the arrow keys to select Alternate DNS Server and enter the IP address of the alternate DNS server.
d. Use the arrow keys to select Hostname and enter the hostname.
Note: Ensure that you enter the entire hostname, including the domain name.
e. Press Enter to accept the DNS Configuration updates.
10. If you have a VLAN configured on the switch to which the ESXi is connected, use the arrow keys to select VLAN (optional) and press Enter.
Enter the VLAN for this network connection and press Enter to accept the change.
Press Esc to exit the Configure Management Network window which you are in now.
11. Use the arrow keys to select Test Management Network and press Enter.
You can see the addresses to be pinged and the hostname to be resolved. Use the arrow keys and select the address to be pinged and press Enter. The test pings your default gateway and DNS servers and tests the connectivity. Press Enter when the test is complete.
At this point, ESXi listens on the IP address that you configured.
12. Use a browser to connect to the IP address configured for ESXi.
A window displaying VMware ESXi 6.5 Welcome appears.
Note: If a warning message about an untrusted SSL certificate appears, select the appropriate action based on your security policy.
Configuring Cisco Prime Network Registrar Virtual Appliance
The Cisco Prime Network Registrar Virtual Appliance is delivered as a virtual machine installed on the ESXi hypervisor. The virtual machine names as shipped from Cisco are “Cisco Prime Network Registrar Local” and “Cisco Prime Network Registrar Regional”.
Note: You may change the virtual machine name as per your choice, however, the underlying disk storage will remain under the name originally used to deploy the OVA (for example, Cisco Prime Network Registrar Local).
To manage the virtual machine containing Cisco Prime Network Registrar, as well as manage any other virtual machines which you may deploy on the Jumpstart, use the VMware web client to connect to http:// esxip, where esxip is the IP address designated to the ESXi hypervisor.
To configure the Cisco Prime Network Registrar Virtual Appliance:
1. After deploying the OVA files, click the virtual machine name and click the Console link.
Note: To deploy the OVA files, see the “Deploying the Regional Cluster OVA or Local Cluster OVA” subsection of Cisco Prime Network Registrar 9.1.1 Installation Guide.
2. You will be prompted to enter a root (system) password, which is not the Cisco Prime Network Registrar password.
Note: This is the root password for the underlying Linux operating system on which the Cisco Prime Network Registrar 9.1.1 application is installed. You will be asked to enter this password twice. You will need root access to the underlying Linux operating system later on, so make sure that you remember this password.
3. Read the end user license agreement and if you agree with the terms stated, accept the agreement by entering y (Yes).
4. Log in to the server as the root user.
5. To configure the network for the Virtual Appliance, see Configuring Network Access on CentOS 7.4 using nmcli.
Configuring Network Access on CentOS 7.4 using nmcli
The NetworkManager command-line tool (nmcli) provides a command line way to configure networking by controlling NetworkManager. This section provides only an overview with some examples to help you learn how to use nmcli to configure network access on the virtual appliance.
In a departure from previous approaches to network interface configuration, NetworkManager deals with both connections and interfaces (also known as devices). Connections are configured with IP addresses, gateways, DNS servers, and then applied to interfaces (devices). This is a critical change from the past way of configuring network access on CentOS Linux.
First, there are two nmcli commands that are of general usefulness:
■The nmcli d command lists all available network interfaces (devices).
■The nmcli c command lists all available configurations.
Use the above two commands frequently as you are learning to use nmcli.
Follow the steps below to configure an IP address for an interface on your virtual appliance. Typically these commands are typed directly into the console of the virtual appliance. If you are already connected through the network (for example, by ssh), then making changes to the network interface configuration can be problematic, as you may also lose network connectivity (and thereby your ability to issue nmcli commands) at any point in the process.
1. Make sure that the interface does not block nmcli. The nmcli d command lists the existing interfaces. If the interface you want to configure is listed as unmanaged, then NetworkManager has been explicitly blocked from configuring this interface. Until you remove this blockage, no nmcli command will have any effect on this interface. Note that you may not need to perform this procedure unless the interface is listed as unmanaged. Follow the steps below to allow it to be managed by NetworkManager:
a. Remove the line NM_CONTROLLED-no from the file /etc/sysconfig/network-scripts/ifcfg-<interface>, where <interface> is the interface name listed in the nmcli d command. If there is no file with this name, then you do not need to perform this procedure.
b. NetworkManager must be told to read the configuration files again. To do this, give the following command:
nmcli connection reload
Note: Manual changes to any ifcfg file will not be noticed by NetworkManager until the following command is issued: nmcli connection reload
2. Make sure that there is no current configuration for the interface that you want to configure. If you want the configuration that you create to be the default for the interface and there are multiple configurations associated with an interface, it may lead to confusion when the system reboots. The nmcli c command lists the existing configurations. If you see any existing configurations, examine them to see if they apply to the interface you want to configure. An easy way to do this is to use the following command:
nmcli con show <config> | grep <interface>
If you see any output, you should remove the configuration <config> with the command:
Note: There is often a configuration called “Wired connection 1” which needs to be deleted.
3. Create the configuration and associate it with the interface (device) in one command. This command only creates the configuration and associates it with the interface, it does not apply it to the interface.
nmcli con add type ethernet con-name <config> ifname <interface> ip4 <ip>/<netmaskwidth> gw4 <gateway>
where <config> is the name of the configuration, which can be anything (including the name of the interface), <interface> is the name of the interface (device), <ip> is the IPv4 address, <netmaskwidth> is the network mask width, and <gateway> is the IPv4 gateway address.
Example (type all in one line):
nmcli con add type ethernet con-name my-office ifname ens160 ip4 10.10.24.25/24 gw4 10.10.20.174
4. Add the DNS server to the configuration for the interface (device):
nmcli con mod <config> ipv4.dns <dnsip>
where <dnsip> is the IPv4 address of the DNS server and <config> is the name of the configuration.
nmcli con mod my-office ipv4.dns 72.63.128.140
You can add two DNS addresses as given below:
nmcli con mod my-office ipv4.dns "72.63.128.140 72.63.111.120"
Note: This will replace any previously set DNS servers. To add to an previously set DNS entry, use the + before ipv4.dns as shown below:
nmcli con mod test-lab +ipv4.dns "72.63.128.140 72.63.111.120"
5. Apply the configuration to the interface, which will bring up the interface if it was not already running:
where <config> is the name of the configuration.
6. Use the following command to examine information about a connection. You may examine information about a connection by using this command:
This will typically scroll off of the console screen, leaving the beginning unreadable. To allow you to move back and forth and examine the output easily, use this command:
nmcli -p con show <config> | less
From this, you can see the entire configuration. You can modify things in the configuration with:
nmcli con mod <config> <something>.<other> <new-value>
nmcli con mod my-office wifi-min.key-cntl wpa-psk
7. Use the command set-hostname to set the hostname for the system:
hostnamectl set-hostname <hostname>.<domain>
Note: This must be done before registering the local to the regional, otherwise an error will result about “localhost” already existing.
where <hostname> is the hostname you want to use and <domain> is the domain name, ending with.com,.org, and so on. It is important to include the domain name (along with the.com,.org, or whatever ending is appropriate), since this is used as the default for DNS lookups.
hostnamectl set-hostname my-server.gooddomain.com
8. After you configure the networking you must restart CPNR in order for the interfaces to be properly discovered by CPNR. Use the following commands to restart: /etc/init.d/nwreglocal restart (for Local RHEL/CentOS 6.x) or systemctl restart nwreglocal (for Local RHEL/CentOS 7.x), /etc/init.d/nwregregion restart (for Regional RHEL/CentOS 6.x) or systemctl restart nwregregion (for Regional RHEL/CentOS 7.x). If you fail to restart, it will result in a misconfigured registration at the regional.
To develop a complete understanding of the usage of nmcli, search the internet for online resources on nmcli and CentOS 7.4.
Configuring Cisco Prime Network Registrar to Automatically Power Up
There are several layers of processing involved in running the Cisco Prime Network Registrar application. Each layer has choices it can make about what to do when it is first powered up after power failures.
You can configure the Cisco Prime Network Registrar to start automatically when power is restored to the Jumpstart.
The two places where you have to change the configurations to make this possible are:
■UCS Hardware—The UCS hardware has to be configured to power up the ESXi hypervisor when power is restored.
■ESXi Hypervisor—The ESXi hypervisor has to be configured to power up the Cisco Prime Network Registrar virtual appliance when power is restored to the ESXi hypervisor layer.
To configure the UCS Hardware to automatically power up the ESXi hypervisor:
1. Connect to the CIMC UCS Management Console at http:// cimcip using a browser and log in. cimcip is the address of the CIMC port.
2. Click the Navigation toggle button on the upper left.
3. In the Compute tab on the left pane, click the Power Policies tab.
4. Select Power On from the Power Restore Policy drop-down list in the Power Restore Policy area.
If you want, you can enter a delay value in the Power Delay Value field.
5. Click Save Changes to save the updates.
To configure the ESXi hypervisor to automatically power up the Cisco Prime Network Registrar virtual appliance when power is restored to the ESXi hypervisor layer, see the “Configuring the Virtual Appliance to Automatically Power Up” section of Cisco Prime Network Registrar 9.1.1 Installation Guide.
Licensing the ESXi Host
The VMWare ESXi host will run on a 60-day Evaluation Mode license once it is powered up. The host license that you receive when purchasing a Jumpstart must be applied to license the server. It will be in the following format:
1. Connect to the ESXi host using the VMware web client.
2. In the navigation pane on the left, choose Manage under Host, and then click the Licensing tab.
3. Click the Assign license button and enter the License key in the pop-up dialog.
