Hi All
I facing Problem about Actual MTU will decrease after connected. please let me know algorithm to calculate Actual MTU. i need to find down why mtu decrease.
You need to adjust both L2MTU and MTU values for interface, and if interface is part of a bridge, check MTU values for the bridge and other bridge ports as well.
