Note

  • 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.
  • For software based DNS cache acceleration appliances, all smartnic CLI commands are replaced by dns-accel CLI commands. For example,  set smartnic log CLI command is replaced by set dns-accel log CLI command.

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–Displays 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 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.

The CLI commands listed below are frequently used on the appliance. For more information see docs.infoblox.com, CLI section.

set dns

The set dns command enables you to control the DNS cache. You can flush the cache of a DNS view or flush a particular entry from the cache.

Syntax

set dns flush all [dns_view]
set dns flush name [dns_view]

ArgumentDescription
allFlushes the cache file from the default view.
dns_viewSpecifies a particular DNS view.
nameFlushes the specific entry from the cache.

Example

Infoblox > set dns flush name accounting.corp100.com
Infoblox > set dns flush all

show dns

The show dns command displays DNS query statistics for all DNS views in the IB-4030 or IB-4030-10GE appliance. It also displays the recursive cache for the specified DNS views.

Syntax

show dns {stats | cache [wait_time ntime][dns_view...]}

ArgumentDescription
stats Displays DNS query statistics for all DNS views. If the DNS Cache Acceleration service is enabled, show dns stats will show the combined statistics for BIND and DNS Cache Acceleration service.
ntime The maximum time (from 1 to 600 seconds) to wait for the cache file to be ready.

Example

Infoblox > show dns stats
success 6718810
referral 0
nxrrset 0
nxdomain 0
recursion 257
failure 0

set smartnic log

Sets the logging level for the DNS Cache Acceleration service on the IB-4030 or IB-4030-10GE appliance, where the level is between 0 being the least verbose and 7 being the most verbose.

Syntax

set smartnic log {level]

Argument Description
level The logging level (from 0 to 7) of messages.

Example

Infoblox > set smartnic log 7


set dns-accel log

Sets the logging level for the DNS Cache Acceleration service on software-based DNS Cache Acceleration appliance, where the level is between 0 being the least verbose and 7 being the most verbose.


Example


Infoblox > set dns-accel log 7

show smartnic

The show smartnic  command checks the status and settings of the DNS Cache Acceleration service.

Note

When you use this command on a specific appliance, the configuration applies only to that appliance. When using this command for an HA pair, you must run the command separately on both the active and passive nodes to ensure consistent behavior.

The show smartnic command displays the following operating characteristics of the IB-4030 or IB-4030-10GE:

  • Firmware version
  • DNS query statistics
  • Cache status, enabled/disabled
  • DNS per-port packet count
  • Cache hit count
  • Log level
  • Cache miss count
  • Failed cores (if any)
  • DNS minimum cached TTL

Syntax
