The NIOS-Software based DNS cache acceleration appliances provide 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 software based DNS cache acceleration appliances IB-4030 or IB-4030-10GE and login with the appropriate admin account.
The Software based DNS cache acceleration appliances support 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.

Supported software based DNS cache acceleration appliance 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 software based DNS cache acceleration appliances 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 software based DNS cache acceleration appliances 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 software based DNS cache acceleration appliances IB-4030 or IB-4030-10GE with an active DNS Cache Acceleration license.
  • set interface–Defines port speed and duplex settings for all supported interfaces.
  • show dns-accelinterface–Shows the status and configuration of a chosen port.
  • show smartnic–Shows the cusrrent status of the appliance. This command applies only to software based DNS cache acceleration IB-4030 or IB-4030-10GE appliances.
  • show dns accel smartnic-cache–You can view the current accelerator cache contents or view the prior cache dump file. This command may affect DNS query response performance for around 15 seconds during execution. This command applies only to software based DNS cache acceleration appliances, IB-4030 and IB-4030-10GE appliances with DNS cache acceleration license enabled.
  • set dns-accel 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 dnssmartnic-accel-cache existing-file–Displays the existing cache data file of software based DNS cache acceleration appliancesIB-4030 and IB-4030-10GE.

The CLI commands listed below are frequently used on the appliance. For detailed information about the supported CLI commands, refer to the Infoblox CLI Guide.
