Adjusts the TCP maximum segment size (MSS) to improve the throughput for the TCP session over a Fabric Extend (FE) adjacency.
default ip tcp adjust-mss
ip tcp adjust-mss [<max-segment-size>] [enable]
no ip tcp adjust-mss enable
Specifies the Maximum Transmission Unit (MTU) size for each packet. Different hardware platforms support different MTU ranges. Use the CLI Help to see the available range for the switch.
The default varies depending on hardware platform:
For XA1400 Series, this functionality is enabled, when at least one Fabric Extend (FE) tunnel with a MTU less than or equal to 1500 is configured, and the value is auto-derived.
For VSP 4900 Series and VSP 7400 Series, this functionality is disabled. The default value, when enabled, is 1300.
