All Ping Commands Over a Size Of 525 Bytes Are Getting Fragmented After Running An Over-Sized Ping Higher Than The Current MTU Value. (Doc ID 2240018.1)

Last updated on APRIL 03, 2017

Applies to:

Oracle VM - Version 3.3.1 and later
Information in this document applies to any platform.

Symptoms

The network has been configured to support a MTU of 9000 bytes , when making a ping test to make sure packets with a size higher than 1500 bytes can be transmitted, the ping command does not go through and the below error is seen, this only happens when using the " -M do " flag on the ping command, other wise this will work fine.

 

This is a normal test with a packed size of 525 bytes.
