Dear All
To find the optimum MTU size , on the MS Windows client , we need to try for "C:\ping www.google.com -f -l 1472" and then do for trial and error to find the optimum size . Can you please do me favor and let me know what is the equivalent of "ping -f -l" on the Linux server ?
Let me thank you in advance

Ok I give up, what are the -f and -l switches on the MS ping command do?

Looks like -l might be packet size...so you might be after this:

-s packetsize
Specifies the number of data bytes to be sent. The default is 56, which translates into 64 ICMP data bytes when combined
with the 8 bytes of ICMP header data.

But just run ping --help and read....

in Windows -l is send buffer size and -F is set don't fragment flag in packet
