What is MTU? In networking, maximum transmission unit (MTU) is a measurement representing the largest data packet that a network-connected device will accept.Imagine it as being like a height limit for freeway underpasses or tunnels: Cars and trucks that exceed the height limit cannot fit through, just as packets that exceed the MTU of a network cannot pass through that network. The maximum transmission unit (MTU) is the largest size frame (packet), specified in bytes, that can be sent over a network interface. The MTU is a configurable setting. The default MTU used on Azure VMs, and the default setting on most network devices globally, is 1,500 bytes. MAC/Layer-2/L2 MTU. L2MTU indicates the maximum size of the frame without MAC header that can be sent by this interface. Starting from the RouterOS v3.25 L2MTU values can be seen in "/interface" menu. L2MTU support is added for all Routerboard related Ethernet interfaces, VLANs, Bridge, VPLS and wireless interfaces.

Network maximum transmission unit (MTU) for your EC2

Online MTU test allows you to test the maximum MTU size from our host to your destination. To check your MTU, simply provide your IP or DNS hostname. We will test the PMTU (Path Maximum Transfer Unit) aka maximum MTU size (unfragmented) between our host and your destination, most likely the outside of your router or firewall.
