[Help] CRS125 MAC/Port Filtering

I own one CRS125 with 20 ports switched.

Using Switch → FDB’s → Unicast FDB I see all MAC’s as dynamic entries from some ports. I can also create static entries, but dynamic entries will continue to fill up this list.

Is any way to disable the dynamic entries at all ?
Can we disable it for specific ports ?

In general I want to have all ports switched and allow specific MAC’s from specific ports.

any suggestion?
