From NIOS 9.0 onwards, IB-4030 and IB-4030-10GE appliances are not supported. |
To achieve optimal DNS query resolution performance, ensure that the switching infrastructure surrounding the IB-4030 or IB-4030-10GE can handle high performance gigabit ethernet traffic load. Efficient IB-4030 or
IB-4030-10GE operation requires switches with adequate memory buffer capacity and support for 1000Base-TX full duplex operation.

Enabling the DNS Cache Acceleration Service
| Note | ||

NIOS 9.0.4 onwards, ensure that DNS recursion checkbox is enabled at the Grid/Member/view level before you start the virtual DNS cache acceleration service. You can select to start the DNS Cache Acceleration Service first. Should you do so, the appliance will also start the DNS service and display a notification that it is doing so. |
To enable the DNS Cache Acceleration service on the DNS Cache Acceleration appliances, do the following:
- From the Grid tab, select the Grid Manager tab and click DNS Cache Acceleration.
- Select the Grid_member check box for the appliance.
- Click the Start icon to activate the DNS Cache Acceleration service on the appliance.
- To disable DNS Cache Acceleration Service: click the Stop icon.
Ensure that DNS recursion checkbox is enabled at the Grid/Member/view level.
If the DNS Cache Acceleration appliance is an independent appliance, do the following:

To enable the DNS name resolution service for an installed DNS Cache Acceleration appliance in an Infoblox Grid:
...
Each DNS response cached in the DNS Cache Acceleration appliance has its own TTL (Time-To-Live) value. For example, entering a value of 3599 seconds (1 hour-1 second) ensures that the appliance caches all DNS responses with a defined TTL of one hour (3600 seconds) or greater. All DNS responses with TTL values of 3599 seconds or less will not be cached by the appliance, and will instead be cached by non-accelerated cache server.
To specify Grid DNS cache acceleration settings:
