NetScaler VPX - Initial Configuration

If you haven’t already read my Installing NetScaler VPX on Client Hyper-V (Windows 10) post, start there and come back here when you’re good to go.

What I have done since that post is:

  • I have downloaded an updated version of the NetScaler 11.1, 10.5 was used in that post
  • I have repeated the steps in that post for a second NetScaler so I can configure a HA pair

Initial Configuration

Initially you will want to configure the following:

  • At least one Subnet IP Address (SNIP)
  • The Hostname and DNS Server/s
  • Install the license
  • Configure NTP
  • Change the NSROOT password and optionally add another user to administer the device with

The Welcome wizard makes many of these steps a little easier, I will use the wizard for the steps below but also show you where the configuration is saved by the wizard.

Add a SNIP

1. Click the Subnet IP Address option in the wizard

image

2. Enter in a SNIP mask combination and click Done

image

You can check it out later, the above information is saved in System –> Network –> IPs –> IPV4s (shown below)

image

Configure the Hostname, DNS Servers and Time Zone

1. Click The Host Name, DNS IP Address, and Time Zone step in the wizard

image

2. Enter a hostname for the NetScaler, Enter at least one DNS Server, select the Time Zone and click Done

image

3. You will likely be asked to reboot, go ahead and do that

image

You can check it out later, the Time Zone is saved in System –> Settings (Shown below)

image

The DNS Server/s are saved in Traffic Management –> DNS  -> Name Servers (Shown below)

image

The Hostname can be changed at any time by re-entering the welcome wizard or by using the CLI

To quickly view the Hostname, click your username in the top right

image

License the NetScaler

1. Click the Licenses step in the wizard

image

2. You have a few options for adding a license. I’m going to use a License Access Code

image

3. No matter how you add the licenses, you will need to reboot after adding them, so go ahead and do that

image

4. After restarting, you will be told what you have been licensed for, and the wizard should disappear

Returning to the Wizard

If you want to return to the wizard at any time, select the “Cog” in the top right corner of the menu

Configure NTP

It’s important for your NetScaler to have a reliable time source, so it’s best to configure an NTP server

1. Select Configuration in the top menu

image

2. Select System and then NTP Servers in the left menu

image

3. Click Add

image

4. Enter an NTP server address and click Create

image

5. Repeat the process for any additional NTP Servers

image

You may need to enable NTP synchronisation, to do this follow the steps below:

6. Click the Select Action drop down menu

image

7. Select NTP Synchronisation

image

8. Select ENABLED and click OK

image

9. Save your configuration by clicking the Save Configuration icon in the top right

image

Change the default password

1. Click Configuration in the top menu

image

2. In the left menu, select System –> User Administration –> Users

image

3. Select the checkbox next to the nsroot user and click Change Password

IMPORTANT: The nsroot passwords on a HA pair of NetScaler devices must match

You now have a One-Arm NetScaler deployment. In the next post, we will configure High Availability
