C5x maximum MTU


We are planning to user C5x PtP as backup for our fiber optic customers, but some of our customers have big MTU (1600/1700 and etc.) request. I read about this in a Mimosa community post:

But there is no option in: Management >> Miscellaneous >> Jumbo Packet Support (set the slider to “On”)

Do you know what is the default MTU, maximum MTU and how can we set it.

In PTP mode the C5x radios don’t have support for User adjustable MTU.
