Hello!
Sorry, my english is bad =(

I tested learning mac address in crs-106. My steps: switch - ports, i check "learning-override" and "learning-limit". After I uncheck this option for back to default settings (!learn-override, !learn-limit). But! In "bridge"-"ports" in tested port in tab "status" i see check "learning". I dont stand why.
And after someone time client in tested ports not work (as learning is on and learn-limit = 0. After i again enable learning-override and set learn-limit - client from port start working.
Why I can restore default behavior?
