Configure Offline (Air-gapped) Licensing on 9800 WLC

Introduction

This document describes how to configure offline (air-gapped) licensing on Catalyst 9800 Wireless LAN Controller (WLC).

Prerequisites

Requirements

Recommended knowledge of 9800 WLC and CSSM (Cisco Smart Software Manager) portal basic operation.

Components Used

The information in this document is based on these software and hardware versions but applies to all versions after 17.3:

• Virtual 9800-CL WLC version 17.9.5

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Configurations

Step 1. On the WLC

1. Set Licensing connection mode to Air Gap and AirGap Feature to Enabled:

The CLI equivalent is:

9800-17-09-05(config)#license smart transport off

2. Export the RUM report from the WLC. This saves your current license consumption to a file:

9800-17-09-05#license smart save usage all file bootflash:rum.txt

Step 2. On the CSSM

1. Log into your CSSM account.

2. Navigate to Reports tab, then Usage Data Files. Click Usage Data Files:

3. Click Browse, then select the RUM report that was obtained from the WLC. Click Upload Data:

4. Once the RUM report is uploaded to the CSSM, the Download button appears under the Acknowledgement column. Click Download:

Step 3. On the WLC

Import the ACK on the WLC:

9800-17-09-05#license smart import bootflash:ACK_rum.txt
Import Data Successful

Note: After a license factory reset, you must wait at least 1 hour to generate the RUM report.

Verify

After applying the configuration steps above, the WLC appears on the CSSM under Inventory > Product Instances.

If an active WLC from the HA pair was registered, both active and standby WLCs are shown under the Product Instances tab on CSSM.

Example of an output from a successfully configured WLC:

Troubleshoot

If the RUM upload to the CSSM portal fails, it can be because your WLC is already registered through direct connection on the portal. Delete the device from the CSSM inventory. You can then upload the RUM report.
