Change MTU size error message

[Georg Pauwen]

When I try to change the MTU size on e.g an Ethernet interface, I get the error message "%Interface Ethernet0 does not support user settable mtu".

Is there a list out there of interfaces that DO support changing the MTU size ?

Thanks for your help in advance.

Regards,

Georg

You cannot change the MTU on ethernet interface(it's fixed at 1500). Some interfaces where you can change MTU are serial, gigabit ethernet
