Thanks, this is what I need. Unfortunately, this option is only for CRS1xx/2xx series switches, newer series (CRS3xx) hasn't it. And it is not included generally in bridge options usable for all RB.
many of us will miss the CRS 1xx/2xx switches, a lot more versatile and powerful than CRS3xx.
the sin and cause of limited success of CRS 1xx/2xx was their complex and unique way of configuring simple thinks like vlans, but the range of functionalities and versatility was magnificent
CRS3xx are a simpler switches, with less functionalities but simpler to configure, that make them much more popular and successful.
Maybe in a future when mikrotik manages to penetrate the switching market more significantly there is a space for a separate line of switches with advanced features like CRS1xx/2xx
CRS 1xx/2xx were too good to be an introductory product
There is no doubt CRS 3xx are more much successful than CRS1xx/2xx making a name for mikrotik in entry level manageable switching market
