Jumbo frames 493g

Hi,

I understand that the 493g cannot do jumbo frames. What I can’t find is whether this is because of the switch chip or the logic in the rest of the board. Would it be able to use jumbo frames between 2 ports that are in switch mode?

MAX L2MTU for interface is hardware limitation. You should choose ppc board to get hardware that is capable to transmit and receive larger packets.
