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 11.1 application software

• AlmaLinux 8.6 Operating System

• VMware ESXi 7.0.3 Hypervisor

• Cisco UCS C220 M6 Hardware

These components are integrated together into a single flexible and easy to use appliance (see the following figure).

Above figure 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 https://vaip:8443 for local and https://vaip:8453 for regional, where vaip is the virtual appliance IP address (which is also the IP address of the Linux Operating System).

  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 vKVM console to get access to the ESXi configuration screen and manage hardware (power, temperature, fan RPM).

The items concerning the networking environment are as follows. These are not unique to the virtual appliance, but are instead values that are determined by the environment in which you will deploy the virtual appliance.

• The IP address or DNS name of the ESXi installation on which you intend to deploy the virtual appliance.

• The IP address or DNS name of any vCenter server associated with the ESXi installation, above.

• Netmask associated with the IP address for the virtual appliance.

• Gateway address appropriate to the IP address and netmask.

• IP addresses of up to two DNS servers for the virtual appliance to use.

• Any proxy values necessary for the virtual appliance to access the Internet.

Note	Ensure that you have the Cisco Prime Network Registrar licenses from Cisco.com before you get started. For details, see the "License Files" section of Cisco Prime Network Registrar 11.1 Installation Guide.

Cisco Prime Network Registrar Jumpstart

Be ready with the following information when configuring the Cisco Prime Network Registrar Jumpstart:

• IP address for the CIMC port on the Cisco Prime Network Registrar Jumpstart.

  Note	This IP address must be unique for this appliance.

• Netmask (subnetmask) for the CIMC port address.

• Gateway for the CIMC port address.

Network information for ESXi

By default, DHCP is enabled in the ESXi configuration. If IP address needs to be manually set, be ready with the following information when configuring network information for ESXi:

• IP address for the ESXi installation on the Cisco Prime Network Registrar Jumpstart.

  Note	This IP address must be unique for this appliance.

• Netmask for the IP address for the ESXi installation.

• Gateway address for the ESXi installation on the Cisco Prime Network Registrar Jumpstart.

• VLAN (if any) for the ESXi installation on the Cisco Prime Network Registrar Jumpstart.

Cisco Prime Network Registrar Virtual Appliance

Be ready with the following information before you deploy the virtual appliance. These items are unique to the installation of this particular virtual appliance.

• A virtual machine name for the deployed virtual appliance.

• A root password for the operating system on the virtual appliance. You will be prompted to enter and configure the root password during your first boot.

• IP address for the Cisco Prime Network Registrar virtual appliance.

• DNS name (hostname) for the virtual appliance. It should be placed into DNS using the IP address you selected for the virtual appliance.

• Username and password for the administrator of the Cisco Prime Network Registrar installation.

Configuring Cisco Prime Network Registrar Jumpstart requires you to do the following configuration steps to connect it to the network:

• Configuring Cisco Prime Network Registrar Jumpstart

• Configuring Network Information for ESXi

• Configuring Cisco Prime Network Registrar Virtual Appliance

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 AlmaLinux.

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:

   1. 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.

   2. 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 nmcli connection reload command is issued.

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:

   nmcli con delete config
   

   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.
   For 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.

   For example:

   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:

   nmcli con up config
   

   where config is the name of the configuration.

6. Use the following command to examine information about a connection:

   nmcli -p con show config
   

   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 using the following command:

   nmcli con mod config something.other new-value
   

   For example:

   nmcli con mod my-office wifi-min.key-cntl wpa-psk
   

7. Use the set-hostname command 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.

   For example:

   hostnamectl set-hostname my-server.gooddomain.com
   

8. After you configure the networking you must restart Cisco Prime Network Registrar in order for the interfaces to be properly discovered by Cisco Prime Network Registrar. Use the following commands to restart:

   • Local RHEL/AlmaLinux 8.x—systemctl restart nwreglocal

   • Regional RHEL/AlmaLinux 8.x—systemctl restart nwregregional

   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 AlmaLinux 8.6.

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 11.1 Installation Guide.

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:

NX61M-43JE6-78J4W-0VB7H-9XHJ4

To license the ESXi host:

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.

This section describes how to recover Cisco Prime Network Registrar Jumpstart 11.1. It includes the following sections:

• Prerequisites

• Downloading the Recovery Kit

• Recovery Procedures

If you encounter any issue for which you are not able to find a solution, contact the Cisco Technical Assistance Center (TAC) for help.

For assistance in troubleshooting, the appliance comes with a secure FTP server and a TAC tool.

Ensure that you send the data gathered by the TAC tool to the TAC team in case of issues. For more details regarding the TAC tool, see Cisco Prime Network Registrar 11.1 Administration Guide.

You can use the FTP server (vsftpd) to transfer files to and from the virtual appliance. You have to create a user to log in to the vsftpd because the 'root' user cannot be used for logging in. The vsftpd will not be up and running when you power on the appliance, so you have to manually start it.

You can start the vsftpd using the command:

/etc/init.d/vsftpd start

You can stop the vsftpd using the command:

/etc/init.d/vsftpd stop
