Tell Packets to Don't Fragment While in Ping Test (ping -f)

So even if the packet size we specified is invalid, we will get reply from the destination. This situation is not good because it fails the actual objective of the ping by giving reply from destination though the packets we send are having invalid size. So it is important to disable fragmentation of packets send from your computer to ensure you are using optimum packet size. We can use ping -f syntax to stop fragmentation of ping packets.


How to Stop Ping Packet Fragmentation Let us explain it by an example. Here we send packets to global DNS address with size 1480 bytes. See the difference with and without the ping syntax -f. By using this syntax, we prevent the packets from dividing and try to reach the destination address with actual size. To change the original packet size, you must use another ping syntax -l. Use of this syntax is explained at t…

Packet Needs To Be Fragmented But DF Set -Reason and Solution

While testing the correct MTU size of your current network, sometimes you may receive the error message "Packet needs to be fragmented but DF set". In this tutorial let us check the reason and solution for this error message. If the MTU size you have set on ping test is too high, you will get this message. Let us check this by an example. Here I am testing whether the MTU value 1480 is the proper value for my network. The ping command to perform this test is:

ping www.corenetworkz.com -f -l 1480
