Sep 10, 2018 · With this setting our servers never transmitted IPv6 packets larger than 1280 bytes, therefore "fixing" the issue. Since all IPv6 routers must have an MTU of at least 1280, we could expect that no ICMP Packet-Too-Big message would ever be sent to us.
When you reach the higher limit, you will see a message like this and you will find the MTU size : > From 192.168.1.1 icmp_seq=1 Frag needed and DF set (mtu = 1500) ping: local error: Message too long, mtu=1500 My answer is based on this one for windows: answer #25165641 Jun 26, 2020 · Gateway MTU vs. system MTU. You must configure your peer VPN gateway to use a MTU of no greater than 1460 bytes. A value of 1460 bytes is recommended because that matches the default MTU setting for Google Cloud VM instances. The effective MTU for peer systems and Google Cloud VMs is typically lower than the MTU of your VPN gateway: From this we need to add on 28 to get the maximum MTU figure. (28 being the header size for IP + ICMP) Do not go above 1472. (1472 + 28 = 1500 MTU) since 1500 is the maximum MTU." So in the above example, does Kitz put 1402 into the router MTU setting, or 1430 ?

To verify the MTU size on Aruba HPE Switch, collect "show tech all" and look for "ghsNetStatShow". This will show the MTU size for all the VLAN interface. There are no CLI commands available to increase/modify default MTU size on Aruba HPE Switch, but jumbo frames can be enabled on respective VLAN, if packet size are found to be exceeding 1500 1468 Your optimum MTU Setting . In your case if the maximum packet size is 1452 the optimal MTU (Maximum Transmission Unit) is 1452+28 i.e. 1480. Here 1452 is the packet size of the data sent but the MTU is 1480. Hope this information is helpful. Amrita M. Microsoft Answers Support Engineer

In networking MTU stands for Maximum Transmission Unit and dictates the maximum size for any packet of data that is sent from a device over a network. MTU is measured in bytes and has a maximum value of 1500, so an MTU of 1500 dictates that the largest packet of data that can be sent in one go from a device over a network is 1500 bytes.
