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 Expressway 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 Expressway in the
meantime.

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.
