configure tunnel tunnel_name ip tcp adjust-mss [off | on tcp_mss_value]


Adjusts the TCP Maximum Segment Size (MSS) on GRE Tunnel.

Syntax Description

tunnel_name Specifies an IPv4 tunnel name.
ip Specifies IP networking.

on Specifies to turn on TCP MSS adjustment.
tcp_mss_value Specifies the value of TCP MSS in bytes. Range is 536-9130.



Usage Guidelines

This command is only available for GRE Tunnel.

For the tcp_mss_value option, because it is an adjustment, there is no default value. When TCP MSS is off, the value is ignored.


The following example configures tcp adjust-mss for tunnel "mytunnel" with an adjust-mss value of 1300:

configure tunnel mytunnel ip tcp adjust-mss on 1300
