Configure the 112-Core Appliance Using the Browser-Based Wizard

Appliance Configuration Overview

You can deploy the 112-core appliance in your network in one of the following modes:

  • Standalone: As a single node offering all the functions. This option is usually preferred for initial or test deployments and in smaller network environments. If you choose Standalone mode for your initial deployment, this will be your first, or primary, node. Note that you can add more appliances later to form a cluster.

  • Cluster: As a node that belongs to a three-node cluster. In this mode, all the services and data are shared among the hosts. This is the preferred option for large deployments. If you choose Cluster mode for your initial deployment, be sure to finish configuring the primary node before configuring the secondary nodes.

To proceed, first configure the primary node in your cluster. Then, if you have installed three appliances and want to add the second and third nodes to your cluster, configure the secondary nodes.

Browser-Based Configuration Wizards

Cisco DNA Center offers two browser-based wizards that you can use to configure your appliance. Read their descriptions to determine which of these wizards you should complete.


Important


These wizards are available for use if you are configuring a new appliance that came with Cisco DNA Center 2.3.3 already installed. If you upgraded from a previous version and want to use these wizards, contact Cisco TAC for assistance.


Install Configuration Wizard

This wizard streamlines the appliance configuration process by setting default values for the Enterprise, Management, and Internet Access interfaces (which all reside on the appliance’s Enterprise port) as well as the Intracluster interface. Use this wizard if you are okay with using the default interface settings and want to get your appliance up and running as quickly as possible. Note that you cannot use this wizard to configure a cluster’s secondary nodes.

Advanced Install Configuration Wizard

This wizard provides access to all of the available appliance settings that you can modify. Use this wizard if you want to specify interface settings that are different from the default settings. Also use this wizard if you are configuring the second or third node in your cluster.

Browser-Based Wizard Prerequisites

To use either of the browser-based wizards and ensure that it configures your appliance properly, complete the following tasks:

  • Designate the Enterprise interface on your appliance to use the IP address, subnet mask, and default gateway that a DHCP server assigns to it. When you configure this interface in the wizard, you will not be able to change the IP address or subnet mask that have been assigned to it. You will only be able to change its default gateway. The topics in this chapter assume that the Enterprise interface was chosen for this purpose.

  • Confirm that the IP address assigned by the DHCP server is reachable by the machine from which you will complete the wizard.

  • For the Enterprise and Intracluster interfaces, verify that both interfaces are connected and in the UP state.

If you want to specify your own IP address, subnet mask, and default gateway for your appliance's Enterprise interface (and not use the values assigned by a DHCP server), ensure that you complete the Static IP Address Settings screen.

Configure an Appliance Using the Install Configuration Wizard

Perform this procedure to configure either a three-node cluster's primary node or a standalone node using the Install configuration wizard. The wizard simplifies the configuration process by setting up the Enterprise, Management, and Internet interfaces on the same port using default settings. The following second generation Cisco DNA Center appliances support configuration using this wizard:

  • 112-core appliance: Cisco part number DN2-HW-APL-XL

  • 112-core promotional appliance: Cisco part number DN2-HW-APL-XL-U


Important


You can only use this wizard to complete the initial configuration of a new Cisco DNA Center appliance. To reimage an appliance that's been configured previously, you will need to use the Maglev Configuration wizard (see Configure the Appliance Using the Maglev Wizard).



Important


You cannot use this wizard to configure the second or third appliance in a three-node cluster. To do so, complete the steps described in Configure a Secondary Node Using the Advanced Install Configuration Wizard. Also, you cannot use this wizard to enable LACP mode on your appliance's Enterprise and Intracluster interfaces.



Note


Ensure that all of the IP addresses you enter while completing this procedure are valid IPv4 addresses with valid IPv4 netmasks. Also make sure that the addresses and their corresponding subnets do not overlap. Service communication issues can result if they do.



Important


Before you configure any of the appliances in a three-node cluster, ensure that you have logged out of those appliances. Otherwise, the Quick Start workflow (which you complete to discover your network's devices and enable telemetry) will not start after you have configured your cluster's appliances and log in to Cisco DNA Center for the first time.


Before you begin

Ensure that you:

  • Installed the Cisco DNA Center software image onto your appliance, as described in Reimage the Appliance.


    Important


    This is only applicable if you are going to configure a promotional appliance, because the Cisco DNA Center software image is not preinstalled on the 112-core promotional appliance (Cisco part number DN2-HW-APL-XL-U).


  • Collected all of the information called for in Required IP Addresses and Subnets and Required Configuration Information.

  • Installed the appliance as described in Appliance Installation Workflow.

  • Configured Cisco IMC browser access on this appliance, as described in Enable Browser Access to Cisco Integrated Management Controller.

  • Checked that the appliance's ports and the switches it uses are properly configured, as described in Execute Preconfiguration Checks.

  • Are using a browser that is compatible with Cisco IMC and Cisco DNA Center. For a list of compatible browsers, see the Release Notes for the version of Cisco DNA Center you are installing.

  • Enabled ICMP on the firewall between Cisco DNA Center and the DNS servers you will specify in the following procedure. This wizard uses Ping to verify the DNS server you specify. This ping can be blocked if there is a firewall between Cisco DNA Center and the DNS server and ICMP is not enabled on that firewall. When this happens, you will not be able to complete the wizard.

Procedure


Step 1

What to do next

When this task is complete:

Configure a Secondary Node Using the Advanced Install Configuration Wizard

Perform the following steps to configure the second and third appliances in the cluster using the Advanced Install configuration wizard.


Important


  • In order to build a three-node cluster, the same version of the System package must be installed on your three Cisco DNA Center appliances. Otherwise, unexpected behavior and possible downtime can occur.

  • The following second generation Cisco DNA Center appliances support configuration using this wizard:

    • 112-core appliance: Cisco part number DN2-HW-APL-XL

    • 112-core promotional appliance: Cisco part number DN2-HW-APL-XL-U



Important


You can only use this wizard to complete the initial configuration of a new Cisco DNA Center appliance. To reimage an appliance that's been configured previously, you will need to use the Maglev Configuration wizard (see Configure the Appliance Using the Maglev Wizard).



Note


Ensure that all of the IP addresses you enter while completing this procedure are valid IPv4 addresses with valid IPv4 netmasks. Also make sure that the addresses and their corresponding subnets do not overlap. Service communication issues can result if they do.



Important


Before you configure the appliances in a three-node cluster, ensure that you have logged out of those appliances. Otherwise, the Quick Start workflow (which you complete to discover your network's devices and enable telemetry) will not start after you have configured your cluster's appliances and log in to Cisco DNA Center for the first time.


When joining each new secondary node to the cluster, you must specify the first host in the cluster as the primary node. Note the following when joining secondary nodes to a cluster:

  • Before adding a new node to the cluster, be sure that all installed packages are deployed on the primary node. You can check this by using Secure Shell to log in to the primary node's Cisco DNA Center Management port as the Linux User (maglev) and then running the command maglev package status. All installed packages should appear in the command output as DEPLOYED. In the following example, a few packages were not installed, such as the application-policy and sd-access packages. They are the only packages whose status is NOT_DEPLOYED. Your package status should look similar to this before configuring a secondary node.

  • Be sure to join only a single node to the cluster at a time. Do not attempt to add multiple nodes at the same time, as doing so will result in unpredictable behavior.

  • Expect some service downtime during the cluster attachment process for each secondary node. Services will need to be redistributed across the nodes and the cluster will be down for periods of time during that process.

Before you begin

Ensure that you:

  • Installed the Cisco DNA Center software image onto your appliance, as described in Reimage the Appliance.


    Important


    This is only applicable if you are going to configure a promotional appliance, because the Cisco DNA Center software image is not preinstalled on the 112-core promotional appliance (Cisco part number DN2-HW-APL-XL-U).


  • Configured the first appliance in the cluster, following the steps in Configure the Primary Node Using the Advanced Install Configuration Wizard.

  • Collected all of the information called for in Required IP Addresses and Subnets and Required Configuration Information.

  • Installed the second and third appliances as described in Appliance Installation Workflow.

  • Have done the following:

    1. Ran the maglev package status command on the first appliance.

      You can also access this information from the Cisco DNA Center home page by clicking the Help icon () and choosing About > Show Packages.

    2. Contacted the Cisco TAC, gave them the output of this command, and asked them to point you to the ISO that you should install on your second and third appliances.

  • Configured Cisco IMC browser access on both secondary nodes as described in Enable Browser Access to Cisco IMC.

  • Checked that both secondary nodes' ports and the switches they use are properly configured, as described in Execute Preconfiguration Checks.

  • Are using a compatible browser. For a list of compatible browsers, see the Release Notes for the version of Cisco DNA Center you are installing.

  • Enabled ICMP on the firewall between Cisco DNA Center and both the default gateway and the DNS server you specify in the following procedure. The wizard uses ping to verify the gateway and DNS server you specify. This ping might get blocked if a firewall is in place and ICMP is not enabled on that firewall. When this happens, you will not be able to complete the wizard.

Procedure


Step 1

Start the Advanced Install configuration wizard:

  1. Point your browser to the Cisco IMC IP address you set during the Cisco IMC GUI configuration you performed, then log in to the Cisco IMC GUI as the Cisco IMC user (see Enable Browser Access to Cisco Integrated Management Controller).

    After successful login, the appliance displays the Cisco Integrated Management Controller Chassis Summary window, with a blue link menu at the upper right, as shown below.
  2. From the blue link menu, choose Launch KVM and then select either Java based KVM or HTML based KVM. If you select the Java-based KVM, you will need to launch the Java startup file from your browser or file manager in order to view the KVM console in its own window. If you select the HMTL-based KVM, it will launch the KVM console in a separate browser window or tab automatically.

    Irrespective of the KVM type you choose, use the KVM console to monitor the progress of the configuration and respond to Maglev Configuration Wizard prompts.

  3. With the KVM displayed, reboot the appliance by making one of the following selections:

    • In the main Cisco IMC GUI browser window: Choose Host Power > Power Cycle. Then switch to the KVM console to continue.

    • In the KVM console: Choose Power > Power Cycle System (cold boot).

    If asked to confirm your choice to reboot the appliance, click OK.

    After displaying reboot messages, the KVM console displays the Maglev Configuration wizard welcome screen.
