After you deploy a NIOS virtual appliance on the VMware platform, you can configure it as a single or an HA Grid Master. To configure a NIOS virtual HA Grid Master, deploy two NIOS virtual appliances and define the network settings for each node. The procedure is the same as joining two physical appliances as an HA pair. You must configure a Grid Master and set up the Grid before you join Grid members. For more information about configuring HA pairs, see NIOS documentation at NIOS.
To configure a NIOS virtual appliance as a Grid Master:
- Deploy the NIOS virtual appliance, as described in Deploying NIOS Virtual Appliances on VMware.
- Specify initial settings on the NIOS virtual appliance, as described in Specifying Initial Settings on NIOS Virtual Grid Masters.
- Configure the NIOS virtual appliance as a Grid Master, as described in Configuring the NIOS Virtual Appliance as a Grid Master. For an HA Grid Master, ensure that you follow the procedures to configure node 2 of the HA pair.
Specifying Initial Settings on NIOS Virtual Grid Masters
After you successfully install the NIOS virtual appliance and start the NIOS virtual appliance, connect to the NIOS CLI and specify the initial settings. For an HA Grid Master, ensure that you specify the initial settings on both nodes.
- From the vSphere Client, select the NIOS virtual instance.
- Select the Console tab.
- Click anywhere in the console screen to activate the console.
- When the Infoblox login prompt appears, log in with the default user name and password.
The Infoblox prompt appears:
You must have valid licenses before you can configure the NIOS virtual appliance. To obtain permanent licenses, first use the
show versioncommand to obtain the serial number of the NIOS appliance, and then visit the Infoblox Support web site at https://support.infoblox.com. Log in with the user ID and password you receive when you register your product online at: https://www.infoblox.com/support/customer/evaluation-and-registration.
If the NIOS virtual appliance does not have the Infoblox licenses required to run NIOS services and to join a Grid, you can use the set temp_license command to generate and install a temporary 60-day license. The appliance lists the available licenses, and you select those you need.
Infoblox > set temp_license
1. DNSone (DNS, DHCP)
2. DNSone with Grid (DNS, DHCP, Grid)
3. Network Services for Voice (DHCP, Grid)
4. Add DNS Server license
5. Add DHCP Server license
6. Add Grid license
7. Add Microsoft management license
8. Add vNIOS license
9. Add IF-MAP Federation license
10. Add Multi-Grid Management license
11. Add Query Redirection license
12. Add Load Balancer license
Select license (1-12) or q to quit:For the vNIOS appliance, select 2 and 8.
You must have both the Grid and NIOS virtual licenses for the NIOS virtual appliance to join a Grid.
- Use the CLI command
set networkto configure the network settings.

Configuring the NIOS Virtual Appliance as a Grid Master
You configure the NIOS virtual appliance as a Grid Master using the Grid Setup wizard. If you are configuring a NIOS virtual HA Grid Master, you complete the configuration for each virtual node in the HA pair as described in this section.
To configure the single Grid Master or node 1 of the HA Grid Master:
- On your management system, open a new browser window, and connect to https://ip_addr, where ip_addr is the address of the single appliance or LAN1 port on node 1.
- Log in using the default user name admin and password infoblox.
- Review the End-User License Agreement and click I Accept.
- In the Grid Setup wizard, select Configure a Grid Master and click Next.
- Complete the following to specify the Grid properties, and then click Next:
- Grid Name: Enter a text string, such as DaveyJones, that the Grid Master and appliances joining the Grid use to authenticate each other when establishing a VPN tunnel between them. The default Grid name is Infoblox.
- Shared Secret: Enter a text string, such as L0ck37, that the Grid Master and appliances joining the Grid use as a shared secret to authenticate each other when establishing a VPN tunnel between them. The default shared secret is test.
- Show Password: Select this to display the password. Clear the checkbox to conceal the password.
- Hostname: Enter a valid domain name for the appliance. You can use the name that you entered for the NIOS virtual appliance when you deployed it.
- Is the Grid Master an HA pair?: Select No for the single Grid Master. Select Yes for an HA pair.
- Complete the following to configure the network settings, and then click Next:
- Host Name: Enter a valid domain name for the appliance.
- IP Address: Displays the IP address of the LAN port.
- Subnet Mask: Displays the subnet mask of the LAN port.
- Gateway: Displays the IP address of the gateway of the subnet on which the LAN port is set.
- Port Settings: The default is Automatic. You cannot change port settings for NIOS virtual appliances.
- For an HA pair, complete the following to specify the network properties and click Next:
- Virtual Router ID: Enter the VRID (virtual router ID). This must be a unique VRID number—from 1 to 255—for this subnet.
- Required Ports and Addresses: Enter information about the following virtual interfaces: VIP, Node 1 HA and LAN ports, Node 2 HA and LAN ports. The VIP address and the IP addresses for all the ports must be in the same subnet. Enter the IP address of the gateway for the subnet on which the interfaces are set. This is the same for all interfaces. All fields are required. Note that you cannot change the port settings.
- Optionally, enter a new password and click Next. The password must be a single hexadecimal string (no spaces) that is at least four characters long.
- Select the time zone of the Grid Master and indicate whether the Grid Master synchronizes its time with an NTP (Network Time Protocol) server, and then click Next.
- If you choose to enable NTP, click the Add icon and enter the IP address of an NTP server. You can enter IP addresses for multiple NTP servers.
- If you choose to disable NTP, set the date and time for the appliance.
The last screen displays the settings you specified in the previous panels of the wizard. Verify that the information is correct and click Finish. The application restarts after you click Finish.
The Grid Setup wizard provides options such as not changing the default password and manually entering the time and date. However, changing the password and using an NTP server improve security and accuracy (respectively), and so these choices are presented here.
Record and retain this information in a safe place. If you forget the shared secret, you need to contact Infoblox Technical Support for help. When you add an appliance to the Grid, you must configure it with the same Grid name, shared secret, and VPN port number that you configure on the Grid Master.
The last screen of the setup wizard states that the changed settings require the appliance to restart. When you click Finish, the appliance restarts.
For an HA pair, complete the following to configure node 2 using the Grid Setup wizard:
- On your management system, open a new browser window, and connect to https://ip_addr, where ip_addr is the address of the LAN1 port on node 2.
- Log in using the default user name and password admin and infoblox.
- Review the End-User License Agreement and click I Accept.
- In the Grid Setup wizard, select Join Existing Grid and click Next.
- Complete the following to specify the Grid properties and click Next
- Grid Name: Enter the Grid name you entered for node 1.
- Grid Master's IP Address: Enter the VIP you entered for node 1.
- Shared Secret: Enter a the shared secret you entered for node 1.
- Verify the IP address settings of the member and click Next.
- The last screen displays the settings you specified in the previous panels of the wizard. Verify that the information is correct and click Finish.
The setup of the HA Grid Master is complete. If the two nodes cannot join (it should not take more than a few seconds), check the IP addresses of Node 1 LAN and Node 1 HA (the Grid Master) and for Node 2 LAN and Node 2 HA (the node attempting to join the Grid Master to form the HA pair). Ensure that the network IP address of node 2 is set to the same value as Node 2 LAN on the Grid Master.
As a method of verifying successful communication, open the console window for node 2. You should see a pair of messages as follows:
Contacting the Grid Master at 10.36.0.200....
Synchronizing database with the Grid Master....
For more information about HA pair configurations, see NIOS documentation at NIOS.
