Adjusts the TCP Maximum Segment Size (MSS) on GRE Tunnel.
| tunnel_name | Specifies an IPv6 tunnel name. |
| ipv6 | Specifies IPv6 networking. |
| tcp | Specifies the TCP protocol. |
| adjust-mss | Specifies to adjust the TCP payload MSS. |
| off | Specifies to turn off TCP MSS adjustment (Default). |
| on | Specifies to turn on TCP MSS adjustment. |
| tcp_mss_value | Specifies the value of TCP MSS in bytes. Range is 536-9110. |
Off.
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 ipv6 tcp adjust-mss on 1300
This command was first available in ExtremeXOS 32.3.
This command is available on the platforms listed for the IPv6 interworking feature in the Switch Engine v33.1.1 Licensing Guide document.
