bwmgr_license is a utility that is used to generate a license request, and to start the bandwidth manager with a test, demo, or full license. It also handles registration of backup disks.

If you are running version 5.0.33 or later, you should use the License section of the ET/BWMGR GUI to generate your license request, retrieve and install your license, and stop/start the BWMGR.


# bwmgr_license start [test] [demo]
# bwmgr_license stop
# bwmgr_license restart
# bwmgr_license license-request
# bwmgr_license register-backup [disk]
# bwmgr_license check-backup [disk]


Issue the "start" command to start the ET/BWMGR. If there is a license installed, the license will be applied. If there is no license installed, the BWMGR will start in "Test Mode", which allows for limited functionality intended to test basic hardware compatibility. Use the test or demo keyword to start in test or demo mode.

# bwmgr_license start

The start command should be the last command in your startup file, which is /etc/rc.bwmgr by default.

Note: In versions prior to 5.0.32, the "test" keyword was required to activate test mode.

# bwmgr_license start test


Stopping the ET/BWMGR is not normally necessary, but when you are installing a license and have a running demo or test license, you will need to issue a stop command, and then start. You can also do this from the ET/BWMGR GUI.

bwmgr_license stop


If the BWMGR is running and you want to apply a new license, you can use the restart command. restart is the equivalent of doing a stop and then a start without any time gap in between. Note that if the new license fails to start, the BWMGR will be stopped when the command completes.

bwmgr_license restart

License Requests

If you do not have the License section in you ET/BWMGR GUI, you will have to generate the request file and install your license manually on the command line.

When ordering a license or requesting a demo license, you must first generate a license request file and send it to us. You can generate a request file by running the utility as follows. This command will output the name of the request file.

# cd /usr/bwmgr
# bwmgr_license license-request


This will create a file named BWMGR_LICENSE_REQUEST.########, the contents of which we will need to issue the license. To print the license request,


This will print the file name and the contents of the file. Send the entire output, including the file name, and the "##############" lines, and post it on your sales or support ticket. When we receive your license request, we will send the license, which you will need to install in the following location:


Both the BWMGR_LICENSE_REQUEST and BWMGR_LICENSE file should be installed in the directory /usr/bwmgr/.

Once your license file is installed, you should stop (if running) and start the BWMGR - see above.

Register a Backup Disk

The first time you backup to a disk, you should register it as part of your system, which will allow the license to be used on the hardware. This only needs to be done once per backup drive. If you purchased an appliance with multiple hard disks, they are pre-registered.

# bwmgr_license register-backup ada1

Check a Backup Disk

The check-backup command will tell you if a disk is registered properly.

# bwmgr_license check-backup ada1

If the disk is properly registered, you will see the message "Backup Setup OK"
