You can run the mtu command in the interface view to change the MTU of a Layer 3 interface. The MTU of an IP packet is the number of bytes from the IP header to the data of the packet. The IP layer then compares the MTU with. Correctly configuring the MTU value is a prerequisite to ensure normal and efficient communication between devices. - If the MTU is configured too small and the message size is large, it may result in too much message fragmentation, and the message may be discarded by the QoS queue, affecting. Using the mtu command, you can set the maximum transmission unit (MTU) of an interface.
