Usage guidelines
This configuration takes effect only on TCP connections that are established after the configuration and
not on the TCP connections that already exist.
This configuration is effective only on IP packets. If MPLS is enabled on the interface, do not configure the
TCP MSS on the interface.
The MSS option informs the receiver of the largest segment that the sender can accept. Each end
announces its MSS during TCP connection establishment.
If the size of a TCP segment is smaller than the MSS of the receiver, TCP sends the TCP segment without
fragmentation. If not, it fragments the segment according to the receiver's MSS.
