RRL provides the ability to control excessive UDP responses that are identical or almost identical. For more information about how RRL works, refer to the *BIND* *Administrators* *Reference* *Manual* at <span style="color: #0000ff">[*http://www.isc.org/downloads/bind/doc/*](http://www.isc.org/downloads/bind/doc/)</span>.  
You can configure parameters for this feature through the following CLI commands: `set dns_rrl` and `show dns_rrl`. For more information about these commands, refer to the Infoblox CLI Guide.  
You can also log RRL events to the syslog. To enable RRL logging, select **rate-limit** in the **Logging** **Category** when you configure logging for the Grid or member. For more information about how to select logging categories, see *<span style="color: #0000ff">[Setting](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35784616/Using+a+Syslog+Server#UsingaSyslogServer-bookmark2793)</span>*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35784616/Using+a+Syslog+Server#UsingaSyslogServer-bookmark2793)*<span style="color: #0000ff">[DNS](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35784616/Using+a+Syslog+Server#UsingaSyslogServer-bookmark2793)</span>*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35784616/Using+a+Syslog+Server#UsingaSyslogServer-bookmark2793)*<span style="color: #0000ff">[Logging](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35784616/Using+a+Syslog+Server#UsingaSyslogServer-bookmark2793)</span>*[ ](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35784616/Using+a+Syslog+Server#UsingaSyslogServer-bookmark2793)*<span style="color: #0000ff">[Categories](https://infoblox-docs.atlassian.net/wiki/spaces/nios85/pages/35784616/Using+a+Syslog+Server#UsingaSyslogServer-bookmark2793)</span>*[.](http://www.isc.org/downloads/bind/doc/)
