Default Ethernet MTU

The Maximum Transmission Unit (MTU) can be set on interfaces individually, and a common default value can be set in the dataplane as well. Setting the default value allows interfaces to use the proper MTU for the environment without using a manually configured value on every interface.

The dataplane ethernet default-mtu <size> command sets the default MTU for Ethernet interfaces, in bytes. Valid values are from 64 to 9000.
