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.
dataplane ethernet default-mtu <size> command sets the default MTU for
Ethernet interfaces, in bytes. Valid values are from
Any interface that will contain an IPv6 address must have an MTU of
1280 or higher. This includes both the default MTU and MTU values set on
See Interface Configuration Options for information on setting the MTU on an interface directly.
