The NIOS-Software based DNS cache acceleration appliances provide 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 and login with the appropriate admin account.
The Software based DNS cache acceleration appliances support the standard NIOS command-line interface for communicating with the device. For more information, refer to the Infoblox CLI Guide.

  • set dns transfer–Schedules zone transfers. Note that set dns transfer is not used by software based DNS cache acceleration appliances 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 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 with an active DNS Cache Acceleration license.
  • show dns-accel–Shows the cusrrent status of the appliance. This command applies only to software based DNS cache acceleration appliances.
  • show dns accel-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, with DNS cache acceleration license enabled.
  • set dns-accel 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 dns-accel-cache existing-file–Displays the existing cache data file of software based DNS cache acceleration appliances.
