How to view mtu size in wireshark? up vote 2 down vote favorite. i've been reading about maximum transmission unit which is the size of the largest protocol data unit (pdu) that can be communicated in a single, network layer, transaction.. 2. when the switch is doing routing, the ip mtu needs also to be increased before the larger packets can be routed by the switch. use the command below to change the mtu size:. Windows 98/98se (or 95 with dun 1.3) - changing mtu use drtcp to change mtu. mtu and other os for linux, it is a matter of using the ifconfig command (read the main page for ifconfig)..
In my network connection settings, the mtu is set to automatic and i would like to know wich value was automatic selected for it. how to check current mtu value. ask question. to view the current mtu. example (just searching for mtu):. The mtu defines the packet size. different types of data or network links respond differently. to change the mtu on a windows server we’re going to use the netsh command. first, we’re going to use ping to ping a host on our network, using -f and then -l which allows us to define the mtu size.. Begin increasing the packet size from this number in small increments until you find the largest size that does not fragment. add 28 to that number (ip/icmp headers) to get the optimal mtu setting. for example, if the largest packet size from ping tests is 1462, add 28 to 1462 to get a total of 1490 which is the optimal mtu setting..
