Begin increasing the packet size from this number in small increments until you find the largest size that does not fragment.

1472, 1462, 1440, 1400) until you have a packet size that does not fragment:

The results above indicate that the packet needs to be fragmented. Repeat this test, lowering the size the packet in increments of +/-10 (e.g.

At the DOS prompt, type in ping -f -l 1492 and hit the Enter key:.

Type in cmd (Windows 2000/XP) or command (Windows 98/ME) into the Open: field.

In Windows, go to Start and select Run.

For example we try to ping with packet size 1500, without fragmentation.

To do the test, you could use the command ping-f-s on windows OS, ping-M-s on Linux, or ping-D-s on Mac OSX. Some service that sends data over the network will usually add a header in data packets, for example ping.Īt the time of data out of your device, data packet will be coupled with a couple of headers, IP Header among others 20bytes, and ICMP headers 8bytes. What if there are applications that require the data package value is static, then the network admin should be able to determine the size of the data packets will be passed so that packets can be received well.

Too many packages that difragment would result in long queues the packet as well, then the device that receives the packages also have to reconstitute packets that are received. In normal conditions the data package has a size too big will in fragment by the device automatically. If the MTU size is only pegged at a value of 1500 (元 MTU) without adding The MTU type other then for the traffic with service VLAN, MPLS, will not be allowed to pass. The big difference of the value of each MTU type depends on the type of traffic that will be on the handle.

On RouterOS for MTU is divided into several types, namely 元 MTU (IP/Layer-3), L 2.5 MTU (MPLS/Layer 2.5), L2 MTU (MAC/Layer-2), Full Frame MTU. which has a size standard large MTU of each interface. So too on the system MikroTik RouterOS i.e. If there is any damage to the package in the delivery of all the damaged package will be sent by the Protocol TCP (Transmission Control Protocol). Getting longer, the MTU is not reliable data delivery process. Large MTU values do not always effect conferring good. However, if the untukran a small box, then we need to send a few times. Then we simply sends all the data one time using one big box.

If it turns out that the package will be delivered has ukran MTU larger than the MTU of the device that receives the package, then the package will be difragmentasi, or cut into smaller sizes.Ī large MTU value makes it possible to send data faster, imagine if you have a lot of data collected so one big box. If the ip layer accepts packets will be forwarded to the network, then the device will calculate the size of the package if added with 20 bytes ip header. Very rarely do the MTU settings manually on the workstation or host. Setting the MTU is usually done on the kind of networking switches, routers and so on.
