add distance=1 g

set time-zone-na

then i reset config and remove configuration and re configure switch

make new screen

and have wrong work with vlan 20 without any understanding why?!

First of, you should upgrade, one of your devices is using a bridge without hardware offloading. Upgrade to 6.41.x or newer and enable hardware offloading with /interface bridge port set [f] hw=yes

Secondly, you are making a very common mistake:
https://wiki.mikrotik.com/wiki/Manual:L ... th_testing

if you seen sreens i have already ver 6.43rc19 on back winbox device!
and make /interface bridge port set [f] hw=yes via winbox "hardware offload option" and have H flag on every port !
