If you always admin down ports that are not supposed to be in use - this is easily done with a change to the datasource discovery.
The reason we don't set this up by default is we only discover interfaces that are operationally 'up', as most people leave all interfaces admin up, so whether operationally up or not is the thing that matters for discovery.
We don't undiscover interfaces that are operationally down, as that is when you want to alert on them.
If, in your case, all admin up interfaces should be discovered, and alerted on whether operationally up or not, it's easy to set the filters that way. (Although it would result in alerts for admin up interfaces that have never been operationally up.)
Is this regarding Optical interfaces, or the regular datasource?
