Configure a license slave

This topic discusses configuring a Splunk indexer as a license slave. Before you proceed, you may want to review these topics:

• Read "How Splunk licensing works" in this manual for an introduction to Splunk licensing.
• Read "Groups, stacks, pools, and other terminology" in this manual for more information about Splunk license terms.
• Read "Configure a license master" in this manual for instructions on setting up a license master.
• Read "Manage licenses from the CLI" in this manual for help with performing these tasks from the command line.

1. On the indexer you want to configure as a license slave, log into Splunk Web and navigate to Manager > Licensing.

2. Click Change to Slave.

3. Switch the radio button from Designate this Splunk instance, <this indexer>, as the master license server to Designate a different Splunk instance as the master license server.

4. Specify the license master to which this license slave should report. You must provide either an IP address or a hostname and the Splunk management port, which is 8089 by default.

Note: The IP address can be specified in IPv4 or IPv6 format. For detailed information on IPv6 support, read "Configure Splunk for IPv6" in this manual.

5. Click Save. If this instance does not already have an Enterprise license installed, you must restart Splunk. This indexer is now configured as a license slave.

To switch back, navigate to Manager > Licensing and click Switch to local master. If this instance does not already have an Enterprise license installed, you must restart Splunk for this change to take effect.
