The NIOS-based IB-4030 or IB-4030-10GE appliance provides several commands to change settings in the system. To use these commands, you must connect through SSH or connect through the serial console port to the IB-4030 or IB-4030-10GE and login with the appropriate admin account.
The IB-4030 or IB-4030-10GE appliance supports the standard NIOS command-line interface for communicating with the device. For more information, refer to the Infoblox CLI Guide.
The following commands are disabled when the DNS Cache Acceleration license is installed on the appliance:
- set dns transfer–Schedules zone transfers. Note that set dns transfer is not used by the IB-4030 or IB-4030-10GE with an active DNS Cache Acceleration license.
- set monitor dns –Activates DNS monitoring in NIOS. Disabled on the IB-4030 or IB-4030-10GE with an active DNS Cache Acceleration license.
- show monitor dns –Displays DNS network monitoring data. Disabled on the IB-4030 or IB-4030-10GE with an active DNS Cache Acceleration license.
Supported IB-4030 and IB-4030-10GE CLI commands include the following:
