Do Not Fragment bit in Fabric Engine 'Ping'

[tcsr121]

Hi
I want to test MTU between two Fabric Extend endpoints both running 9.0.4 that traverse a third party network where the third party does not always set the path MTU to allow FE (it's usually 1900 end to end).
I'm pinging from the tunnel interface on our core switch to a remote logical interface address that I know works as follows:

     ping 10.a.b.c datasize 1900 vrf fe-int source 10.x.y.x 

This works - but then so does 

     ping 10.a.b.c datasize 9000 vrf fe-int source 10.x.y.x 

as I know the intervening network has a limit of 1900 I'm guessing that packets are being fragmented which makes the test useless. There seems to be no 'do not fragment' option for ping (there is with Cisco). Is there an option I'm missing or a better test on Fabric Engine?? As MTU is limited to 1500 elsewhere I can only check directly between the two Extreme switches.

yes @Jave  I read your post - hopefully more people will ask the same question - odd that the functionality is there in EXOS but not VOSS

Hi @tcsr121 

Already asked for this functionality years ago...with no luck unfortunately.

Regards.
