  • From NIOS 9.0 onwards, IB-4030 and IB-4030-10GE appliances are not supported.
    Similar features are available on software based DNS cache acceleration appliances. You can enable them by using the DNS cache acceleration CLI commands.
    From NIOS 9.0 onwards, all smartnic CLI commands (
  • applicable only for hardware For software based DNS cache acceleration appliances) are replaced by , in CLI commands replace "smartnic" CLI command with "dns-accel" CLI commandscommand.   For example,  replace "set smartnic log, is replaced as " to "set dns-accel log".

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 see docs.infoblox.com, CLI section.

Supported IB-4030 and IB-4030-10GE CLI commands include the following:

  • set dns transfer–Schedules zone transfers. Note that set dns transfer is not used by IB-4030 or IB-4030-10GE with an active DNS Cache Acceleration license.
  • set monitor dns –Activates DNS monitoring in NIOS. This command is disabled on IB-4030 or IB-4030-10GE with an active DNS Cache Acceleration license.
  • show monitor dns –Displays DNS network monitoring data. This command is disabled on IB-4030 or IB-4030-10GE with an active DNS Cache Acceleration license.
  • show dns –Displays DNS query statistics for all DNS views in the IB-4030 or IB-4030-10GE appliance.
  • show smartnic–Shows the current status of the appliance. This command applies only to IB-4030 or IB-4030-10GE appliances.
  • show smartnic-cache–You can view the current accelerator cache contents or view the prior cache dump data file. This command may affect DNS query response performance for around 15 seconds during execution. This command applies only to IB-4030 and IB-4030-10GE appliances with DNS cache acceleration license enabled.
  • set smartnic log–Specify the log level for the DNS Cache Acceleration service on the appliance.
  • set temp_license–Generates and installs a temporary DNS cache acceleration license. You can add a temporary DNS cache acceleration license for up to one million qps. Note that you cannot add a temporary license if a permanent license already exists.
  • show license–Displays the capacity of the applicable DNS cache acceleration license type.
  • show smartnic-cache existing-file–Displays the existing cache data file of IB-4030 and IB-4030-10GE.
