Note

From NIOS 9.0 onwards, IB-4030 and IB-4030-10GE appliances are not supported.
Similar features and functionalities are available on software-based DNS Cache Acceleration appliances, and it is recommended to use the software-based DCA supported appliances. For a list of supported appliances, see as described in Supported DNS Cache Acceleration Appliances.

For initial hardware setup instructions, refer to the NIOS Documentation at docs.infoblox.com. Once you install the system and run the set network command, you enable the DNS service and the DNS Cache Acceleration service on the DNS Cache Acceleration appliances.
The procedure to start DNS Cache Acceleration service consists of the following:

  1. Install and activate the DNS Cache Acceleration license, as described in Licensing Requirements below.
  2. Enable the DNS service and the DNS Cache Acceleration service, as described in enabling the DNS cache acceleration service and enabling the DNS service, see  Configuring DNS Cache Acceleration. 
     

Licensing Requirements

The DNS Cache Acceleration appliance require a DNS Cache Acceleration license. The IB-4030 and IB-4030-10GE support four tiers of DNS Cache Acceleration licenses. These licenses enable DNS caching and control DNS queries per second performance on the appliance. The Tier-4, Tier-3,  and Tier-2 licenses enable the appliance to process up to 150K, 300K and 600K qps (queries per second) respectively. The Tier-1 license enables the appliance to perform at its full capacity.

You can install either a temporary or a permanent license on the appliance. The temporary license provides a 60 days free trial for up to one million queries per second. You can upgrade a temporary license to any of the permanent DNS Cache Acceleration license on the appliance using either Grid Manager or the CLI.

A lower tier license cannot be added for DNS cache acceleration when a higher tier permanent license is installed. You can add a lower tier license if a temporary license exists. You cannot downgrade any permanent DNS cache acceleration license from a higher tier license to a lower tier license. For more information about the different tier licenses, contact your Infoblox representative.
The appliance displays a warning message if the DNS cache acceleration utilization exceeds a predefined threshold. You can configure the appliance for various levels of performance based on your current license type.

Tiered licenses are supported only on IB-40x5 appliances. Other software-based appliances are enabled to perform at their full capacity.

The system restarts automatically when you install the license or upgrade it to a higher tier. For more information about adding and upgrading licenses through Grid Manager, see the NIOS Documentation at docs.infoblox.com.

You can also use the CLI command set license to apply a permanent license or the set temp_license command to add a temporary license. For more information about the CLI command, see DNS Cache Acceleration CLI Commands.
