What for? IIRC that's a thing for a router to tickle with.

You´re looking for an option to allow "jumbo frames", i.e. set a higher value for MTU?

I read somewhere that e.g. the CSR326 does support jumbo frames (I don't see a reason why that should be a setting that can be enabled and disabled - a switch has a certain maximum packet size that it supports, no more, no less) but I couldn't get it to work in my setup between a Win 10 desktop and a FreeBSD box. I cannot rule out admin's (= mine) incompetence, though.

Hello.. The MTU is not able con be configured in SwOS, however, there is a table which helps to know if a CRS or CSS support jumbo frames. Actually, you can find it here: https://wiki.mikrotik.com/wiki/Manual:CRS_features and here https://wiki.mikrotik.com/wiki/Manual:C ... s_switches

But to make it easier, here is the answer:

Jumbo frame support (CRS1xx: 4064 Bytes; CRS2xx: 9204 Bytes)
CRS326 / CRS317 support 10218 Bytes

Are you sure this is also valid for CSS? Doesn't state so in the linked articles.

CRS326 and CSS326 are almost identical, Jumbo frame values are the same.
