It Depends, if MSS MTU is smaller, it will cause chatty communication

 

If Oversized MSS, it will generate can't fragment ICMP

 

F5 LTM will detect client path MTU with following command

 

tmsh show net cmetrics

So if MSS is configured for 536 and path MTU is 1500, what is the max MSS...is it 536 or 1460?
