Issue/Introduction

When the network environment uses jumbo packets, it's important to know the frame size PacketShaper supports.

Resolution

The maximum frame size that a PS12000 will forward is 2000 bytes.

You can change the MTU size on PacketShaper using the MSS system variables:

#
setup variable tcpMssInbound 1960
setup variable tcpMssOutbound 1960
#

Note: MSS is lower than MTU by 40 bytes. (20 bytes for IP header and another 20 bytes for TCP header).
