Prepare for Deployment
In order to prepare for the deployment of a Cisco DNA Center on ESXi virtual appliance, you'll need to complete the following tasks:
Install VMware vSphere
To run, Cisco DNA Center on ESXi requires VMware vSphere (which includes ESXi and vCenter Server) 7.0.x or later, including all patches. Click here to access an overview of the VMware vSphere installation and setup process. After you have installed ESXi, confirm that the ESXi you set up can be reached from the computer that you will use to deploy the virtual appliance's OVA file.
Reserve Enterprise Interface
Before you set up the virtual appliance, ensure that you reserve one 1-Gbps/10-Gbps Enterprise interface to connect to and communicate with your enterprise network. Jot down the IP address for this interface, since you'll need to enter it during appliance configuration.
Optionally, you can also reserve one 1-Gbps/10-Gbps Management network interface to access the Cisco DNA Center on ESXi GUI. Jot down this interface's IP address as well if you plan to configure it.
Note the following points:
-
The intracluster interface's IP address is predefined, so you won't need to enter it when you complete either the Maglev Configuration wizard with default mode selected or the browser-based Install configuration wizard.
-
Cisco DNA Center on ESXi supports the configuration of one additional interface for use by the virtual appliance. If you do so, make sure that you choose VMXNET from the Adapter Type drop-down list. Otherwise, appliance configuration will not complete successfully. For more information, see the Add a Network Adapter to a Virtual Machine topic in vSphere Virtual Machine Administration.
Import the IdenTrust Certificate Chain
The Cisco DNA Center on ESXi OVA file is signed with an IdenTrust CA certificate, which not included in VMware's default truststore. As a result, the Deploy OVF Template wizard's Review details page will indicate that you are using an invalid certificate while completing the wizard. You can prevent this by importing the IdenTrust certificate chain to the host or cluster on which you want to deploy the OVA file.
Procedure
Step 1 |
On the VMware ESXi host or cluster where your virtual appliance will reside, download trustidevcodesigning5-2.3.7.0-VA.tar.gz from the same location that Cisco specified to download the Cisco DNA Center on ESXi OVA file. |
Step 2 |
Unzip this file. |
Step 3 |
Log in to the vSphere Web Client. |
Step 4 |
Choose . |
Step 5 |
In the Trusted Root Certificates field, click Add. |
Step 6 |
In the Add Trusted Root dialog box, click Browse. |
Step 7 |
Navigate to and select the certificate chain you downloaded in Step 1 (trustidevcodesigning5.pem), then click Open. |
Step 8 |
Check the Start Root certificate push to vCenter Hosts check box, then click Add. A message indicates that the certificate chain was successfully imported. When you complete the Deploy OVF Template wizard, the Review details page's Publisher field should indicate that you are using a trusted certificate. |
Prepare NTP and Proxy Servers
You'll be prompted to specify two items:
-
The Network Time Protocol (NTP) server that Cisco DNA Center on ESXi will use for clock synchronization.
-
(Optional) The proxy server that Cisco DNA Center on ESXi will use to access internet-bound URLs.
Before you configure your virtual appliance, do the following:
-
Ensure that the servers you want to use are both available and running.
-
For an NTP server, obtain its IP address or hostname. And for a proxy server, collect either its URL or hostname and its login credentials.
Enable Storage Input/Output Control
For the datastore in which you are planning to deploy a virtual appliance, complete the following procedure so the appliance's virtual machine input/out (I/O) is prioritized over other virtual machines when the network is experiencing I/O congestion.
Procedure
Step 1 |
In the vSphere Client, navigate to and click the datastore in which you plan to deploy a virtual appliance. |
Step 2 |
Click the Configure tab, then click General. |
Step 3 |
In the Datastore Capabilities area, click Edit. |
Step 4 |
In the Configure Storage I/O Control window, do the following: |
Step 5 |
Click OK. |
Check HA Admission Control Setting
You cannot connect Cisco DNA Center on ESXi VMs to create three-node clusters. If you want to enable High Availability (HA), you'll need to use VMware vSphere's HA functionality and enable strict admission control to ensure that:
-
A virtual machine cannot be powered on if it will result in the violation of availability constraints.
-
Configured failover capacity limits are enforced.
-
HA operates as expected during a failover.
For more information, in the Cisco DNA Center on ESXi Administrator Guide, Release 2.3.7, see the "High Availability" section in the "Configure System Settings" chapter.
Prepare for the Quick Start Workflow
After you create a virtual machine on an ESXi host and configure a Cisco DNA Center on ESXi virtual appliance, you'll be prompted to complete the Quick Start workflow. By completing this workflow, you'll discover the devices that Cisco DNA Center on ESXi will manage and enable the collection of telemetry from those devices. In order to complete this workflow successfully, you'll need to perform the following tasks:
-
Decide on the username and password for the new admin user you're going to create. The default admin username and password (admin/maglev1@3) should only be used the very first time you log in to Cisco DNA Center on ESXi.
Important
Changing this password is critical to network security, especially when the people who set up a Cisco DNA Center on ESXi virtual appliance are not the same people who will serve as its administrators.
-
Obtain the credentials you use to log in to Cisco.com.
-
Identify the users that need access to your system. For these users, define their roles as well as unique passwords and privilege settings.
You have the option to use an IPAM server and Cisco Identity Services Engine (ISE) with your virtual appliance. If you choose to use one or both of them, you'll also need to obtain the relevant URL and login credentials.
Deploy a Virtual Appliance
To set up a Cisco DNA Center on ESXi virtual appliance, you'll need to complete the following tasks:
If you want to set up your virtual appliance using the ESXi launcher app, you'll first complete the steps described in Configure a Virtual Appliance Using the ESXi Launcher App. Then you'll complete the Quick Start workflow.
