the MTU of the outgoing interface is used as a starting point, and we can jump down the list when an intermediate router sending a "can't fragment" message includes its next hop MTU (as described in RFC 1191 and required by RFC 1812) Example Usage . nmap --script path-mtu target Document Display | HPE Support Center The default MTU and jumbo frame size is 1500 bytes. User cannot change the MTU on an individual interface. One must set the MTU globally. Reset the switch afterwards for the MTU change to take effect. Configure: Use the system mtu command to change the MTU for all 10/100 interfaces. This command only effects 10/100 interfaces. 3750(config Michigan Tech Single Sign On
Alternative method: ip addr | grep mtu For example: ip addr | grep mtu 1: lo:

So to test for MTU of 9000, you actually need to set your ping packet size to 9000-28 = 8972. By adjusting the MTU value its possible to find the supported MTU value in the network. If the MTU value is not enables in the client side the ping output will be : PING xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx): 8184 data bytes ping: sendto: Message too long
Set MTU in VPN environment in case of throughput issues The MTU Size will be. 1492 Non-VPN traffic MTU Size - X IPSec Overhead. X Definive MTU Size. EXAMPLE: 1492 Non-VPN traffic MTU Size - 73 IPSec Overhead 1419 Definive MTU Size. To set up the new MTU value, you can go under Network | Interfaces, select the WAN interface from which the VPN traffic is going through and: Navigate to Advanced tab.
