Note

From NIOS 9.0 onwards, IB-4030 and IB-4030-10GE appliances are not supported.
Similar features and functionalities are available on software-based DNS Cache Acceleration appliances, and it is recommended to use the software-based DCA supported appliances. For a list of supported appliances, see as described in Supported DNS Cache Acceleration Appliances.
For software-based DNS Cache Acceleration appliances, replace smartnic keyword with dns-accel in the CLI command. 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 the NIOS Documentation at docs.infoblox.com, CLI section.

The CLI commands listed below are frequently used on the DNS Cache Acceleration appliance(s). For more information see the NIOS Documentation, CLI section at docs.infoblox.com.

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. This command is used on software-based and hardware DNS Cache Acceleration appliances.

Syntax

set temp_license

Example

set temp_license

`show license`

The show license command displays the capacity of the applicable DNS cache acceleration license type.

Syntax

show license [ all | csv | gridwide | revoked ]

`Example`

Infoblox > show license all
Infoblox > show license csv
Infoblox > show license gridwide
Infoblox > show license revoked

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]

Argument	Description
`all`	Flushes the cache file from the default view.
`dns_view`	Specifies a particular DNS view.
`name`	Flushes 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...]}

Argument	Description
`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 monitor

This command activates the DNS monitoring in NIOS. This command is applied on software-based DNS Cache Acceleration appliance.

Syntax

set monitor dns

Example

Infoblox > set monitor dns

show monitor dns

This command displays DNS network monitoring data. This command is applied on software-based DNS Cache Acceleration appliance.

Syntax

show monitor dns

Example

Infoblox > show monitor dns

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

You can view information about the SFPs on the IB-4030 or IB-4030-10GE application. To view the details:

From the Grid tab, select the Grid Manager tab
Click the Members tab -> member check box -> Detailed Status icon.

You can also use this command to view the VLAN ID, tagged networks, and additional IP addresses that are configured for the network when you enable VLAN on an IB-4030 or IB-4030-10GE appliance. For more information about enabling VLAN support using CLI commands, see Infoblox DNS Firewall.

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.

Syntax

show smartnic-cache

Example

Infoblox > show smartnic-cache

The following warning message is displayed, after you run this command.

WARNING

This operation will temporarily disable the acceleration cache to obtain the latest cached data.
The operation should take about 15 seconds to complete.
During this period, this member's DNS query performance may be significantly reduced, and changes to the member's DNS configuration will not be permitted.
