To deploy an independent HA pair, you cable the HA and LAN1, LAN1 (VLAN), or LAN2, LAN2 (VLAN) ports to the network and configure the IP settings for these ports and the VIP address within the same subnet. For more information about HA pairs, see About HA Pairs.
The default LAN1 or LAN2 settings are as follows:

  • IP address: 192.168.1.2
  • Netmask: 255.255.255.0
  • Gateway: 192.168.1.1.

You can configure an HA pair using the Infoblox NIOS Startup Wizard. IPv4 and IPv6 network values are supported for the NIOS Startup Wizard and for HA Pair configuration. The NIOS appliance MGMT port also can be configured to support an IPv6 address.

  • Requirements: HTTPS connections from your management system to the Ethernet ports on the two appliances.
  • Advantage: The startup wizard provides step-by-step guidance for configuring the network settings of the VIP address and HA and LAN1 or LAN1 (VLAN) ports on both nodes, for setting the host name, admin password, and system clock, and—if using NTP (Network Time Protocol)—for enabling the HA pair as an NTP client.

Using the Infoblox NIOS Startup Wizar d to Configure an HA Pair

When you first make an HTTPS connection to the NIOS appliance, the Infoblox NIOS Startup Wizard guides you through various deployment options, basic network settings, and opportunities for changing the password of the superuser admin and for setting the system clock.
Configuring the Connecting Switch
To ensure that VRRP (Virtual Router Redundancy Protocol) works properly, configure the following settings at the port level for all the connecting switch ports (HA, LAN1, LAN1 (VLAN), LAN2, and LAN2 (VLAN)):

  • Spanning Tree Protocol: Disable. For vendor specific information, search for "HA" in the Infoblox Knowledge Base system at https://support.infoblox.com.
  • Trunking: Disable
  • EtherChannel: Disable
  • IGMP Snooping: Disable
  • Port Channeling: Disable
  • Speed and Duplex settings: Match these settings on both the Infoblox appliance and switch
  • Disable other dynamic and proprietary protocols that might interrupt the forwarding of packets

Note: By default, a NIOS appliance automatically negotiates the optimal connection speed and transmission type (full or half duplex) on the physical links between its LAN1, HA, and MGMT ports and the Ethernet ports on the connecting switch. If the two appliances fail to auto-negotiate the optimal settings, see Modifying Ethernet Port Settings for steps you can take to resolve the problem.



Putting Both Nodes on the Network

  1. Use one of the methods described in Deploying a Single Independent Appliance to configure the network settings of the LAN1 port of each node so that they are on the same subnet and you can reach them across the network.
  2. Cable the LAN1 port and the HA port on each node to the network switch.

    Note: The Ethernet ports on the TE-810, TE-820, TE-1410, TE-1420, TE-2210, TE-2220, and IB-4010 appliances are autosensing, so you can use either a straight-through or cross-over Ethernet cable for these connections.

  3. Cable your management system to the network switch.


Configuring Node 1

  1. Open an Internet browser window and enter https://* *<the IP address of the appliance> to make an HTTPS connection to the first node. For information about supported browsers, see Supported Browsers.
    Several certificate warnings may appear during the login process because the preloaded certificate is self-signed and has the hostname www.infoblox.com, which may not match the destination IP address you entered in step 1. To stop the warning messages from occurring each time you log in to Grid Manager, you can generate a new self-signed certificate or import a third-party certificate with a common name that matches the FQDN (fully qualified domain name) of the appliance. For information, see Creating a Login Banner.
  2. Enter the default username and password (admin and infoblox) on the Grid Manager login page, and then click Login or press Enter. For information, see Logging in to the GUI.
  3. Read the Infoblox End-User License Agreement, and then click I Accept to proceed. Grid Manager may take a few seconds to load your user profile.
  4. In the first screen of the Grid Setup wizard, select Configure a Grid Master and click Next.
  5. Specify the following:
    • Grid Name: Type the name of the Grid. The default name is Infoblox.
    • Shared Secret: Enter the shared secret that both nodes use to authenticate each other when establishing a VPN tunnel for ensuing bloxSYNC traffic. The default shared secret is test.
    • Confirm Shared Secret: Enter the shared secret again.
    • Host Name: Enter a valid domain name for the node.
    • Type of Network Connectivity: Select the type of network connectivity from the drop-down list:

  7. Click Finish.

The setup of the HA pair is complete. When you next make an HTTPS connection to the HA pair, use the VIP address.
The communication protocol for all the services in a dual mode (IPv4 and IPv6) HA appliance is the same protocol as the one used for VRRP advertisements. For example, if you select IPv4 in the Send HA and Grid Communication Over field on the first screen of the NIOS Setup wizard, then IPv4 is set as the communication protocol for all the services. However, you can override the communication protocol for all the services in a dual mode HA pair. For information, see Changing the Communication Protocol for a Dual Mode Independent Appliance.
