In this case, The Ping command displays one of the local stack's IP addresses as the host address where fragmentation is needed, and the next-hop MTU value displayed by the Ping command is the current path MTU value to the destination. MTU 1525 bytes, BW 100000 Kbit/sec, DLY 100 usec, Now we have the ability to send a frame with an MTU that is just larger than the MTU on R2's fa0/1 link, but that the fa 0/0 link on R2 will still be happy to process. Because the MTU on R2's fa0/1 interface is 1520, let's send a ping with a size of 1521 and the df-bit set. Feb 16, 2018 · Enable jumbo frames on a VMkernel network interface by changing the maximum transmission units (MTU) of the VMkernel interface. The vmkping command will, by default, use any path to reach the destination IP. By specifying an additional parameter we can send out a ping command via a specific vmkernel port. We'll show that option in a minute. 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
