--- title: "DNS Cache Acceleration CLI Commands" canonical: "https://docs.infoblox.com/space/dca9x/399474987/DNS%20Cache%20Acceleration%20CLI%20Commands" format: markdown --- Infoblox NIOS has commands that can be used to change settings related to DNS Cache Acceleration in an appliance that supports DNS Cache Acceleration. To use these commands, you must connect through SSH or connect through the serial console port to the NIOS appliance and log in with the appropriate admin account. The NIOS appliance supports the standard NIOS command-line interface for communicating with the device. For more information see the CLI section in the NIOS Documentation at *[docs.infoblox.com](https://docs.infoblox.com/)*. The CLI commands listed below are frequently used on the DNS Cache Acceleration appliances: > Macro (toc) # 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. 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 dns-accel log Sets the logging level for the DNS Cache Acceleration service on a DNS Cache Acceleration capable appliance. The logging level is between 0 being the least verbose and 7 being the most verbose. ## Syntax `set dns-accel log {level]` | **Argument** | **Description** | | --- | --- | | `level` | The logging level (from 0 to 7) of messages. | ## Example `Infoblox > set dns-accel 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 dns-accel The `show dns-accel`  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 dns-accel` command displays the following operating characteristics of the DNS Cache Acceleration appliance. | | | | --- | --- | | - 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 `show dns-accel` ## Example `Infoblox > show dns-accel` `Firmware version:     1.3.19, Nov 08, 2011` `Cache:                Enabled` `Cache hit count:      109397` `Cache miss count:     3008` `Minimum cached TTL:   10` `DNS query stats:      SUCCESS=109380 NXDOMAIN=0 NXRRSET=0 FAILURE=0 REFERRAL=0` `DNS UDP packet count: port0=299339 port1=93408 port2=0 port3=0` `Log level:            6` `Failed cores:         None` # show dns-accel The `show dns-accel` command displays the following operating characteristics of the software-based DNS Cache Acceleration appliance: `Infoblox > show dns-accel` `Log level:                       6(Info)` `Cache:                           Enabled` `Minimum cached TTL:              1` `Maximum cached lifetime:         86400` `Cache hit count:                 0` `Cache miss count:                0` `DNS query stats:                 SUCCESS=0 NXDOMAIN=0 NXRRSET=0 FAILURE=0 REFERRAL=0` `System UDP DNS query count:      MGMT=0 LAN1=0 HA=0 LAN2=0` `System UDP DNS response count:   0` `System DOH/DOT query count:      MGMT=0 LAN1=0 HA=0 LAN2=0 BOND0=0` `System DOH/DOT response count:   0` `Infoblox >` You can view information about the SFPs on the DNS Cache Acceleration appliance. To view the details: 1. From the **Grid** tab, select the **Grid** **Manager** tab 2. 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 DNS Cache Acceleration appliance. For more information about enabling VLAN support using CLI commands, see *[Infoblox DNS Firewall](https://infoblox-docs.atlassian.net/wiki/spaces/DAAG/pages/10748029)*. # show dns-accel-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 appliances with DNS cache acceleration license enabled. ## Syntax `show dns-accel-cache` ## Example `Infoblox > show dns-accel-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. 1,[88ff8189f2f7548d.pacebook.com](http://88ff8189f2f7548d.pacebook.com/),AAAA,IN,NO,0,1,3600,3557,6828,0,AA,AAAA,[88ff8189f2f7548d.pacebook.com](http://88ff8189f2f7548d.pacebook.com/),3600,356f:3f49:366f:3f49:376f:3f49:386f:3f49,,0,2320,3557 2,[abe4d043815df77d.akamaidn.edu](http://abe4d043815df77d.akamaidn.edu/),A,IN,NO,0,1,3600,3557,1151352,0,AA,A,[abe4d043815df77d.akamaidn.edu](http://abe4d043815df77d.akamaidn.edu/),3600,52.111.63.73,,0,2321,3557 3,[7443b4a129f534b6.applexxx.net](http://7443b4a129f534b6.applexxx.net/),AAAA,IN,NO,0,1,3600,3557,1438037,0,AA,AAAA,[7443b4a129f534b6.applexxx.net](http://7443b4a129f534b6.applexxx.net/),3600,306f:3f49:316f:3f49:326f:3f49:336f:3f49,,0,2322,3557 4,[c42e7ae4ad44b227.pacebook.com](http://c42e7ae4ad44b227.pacebook.com/),AAAA,IN,NO,0,1,3600,3557,492849,0,AA,AAAA,[c42e7ae4ad44b227.pacebook.com](http://c42e7ae4ad44b227.pacebook.com/),3600,396f:3f49:3a6f:3f49:3b6f:3f49:3c6f:3f49,,0,2323,3557 5,[51bd345d7ac2a4b2.facebook.com](http://51bd345d7ac2a4b2.facebook.com/),AAAA,IN,NO,0,1,3600,3557,412,0,AA,AAAA,[51bd345d7ac2a4b2.facebook.com](http://51bd345d7ac2a4b2.facebook.com/),3600,3d6f:3f49:3e6f:3f49:3f6f:3f49:406f:3f49,,0,2324,3557 # show dns-accel-cache The `show dns-accel-cache` command displays the operating characteristics of the software-based DNS Cache Acceleration appliance. ## Syntax show dns-accel-cache ## Example ``` Infoblox > show dns-accel-cache This operation should take about 15 seconds to complete.
