Adding option keys using the web interface
To add an option key:
1. In the Add option key field, enter the key that has been provided to you for the option you want to add.
2. Click Add option.
Some option keys require that the VCS is restarted before the option key will take effect. In such cases you
will receive an alarm on the web interface, which will remain in place as a reminder until the system has been
restarted. However, you can continue to use and configure the VCS in the meantime.
Adding option keys using the CLI
To return the indexes of all the option keys that are already installed on your system:
xStatus Options
To add a new option key to your system:
xConfiguration Option [1..64] Key
Note: when using the CLI to add an extra option key, you can use any unused option index. If you chose an
existing option index, that option will be overwritten and the extra functionality provided by that option key will
no longer exist. To see which indexes are currently in use, type xConfiguration option.
