IP CLI Commands

ip set interface tcpmssclamp

12.18.1 Syntax
ip set interface <name> tcpmssclamp {enabled|disabled}
12.18.2 Description
This command enables/disables TCP MSS (Maximum Segment Size) Clamp
functionality on an existing IP interface. When TCP MSS Clamp is enabled on
an interface, all TCP traffic routed through that interface will be examined. If a
TCP SYN (synchronize/start) segment is sent with a maximum segment size
larger than the interface MTU (Maximum Transmission Unit), the MSS option
will be rewritten in order to allow TCP traffic to pass through the interface
without requiring fragmentation.
