R3204P16-HP Load Balancing Module System Maintenance Command Reference-6PW101

128
Description
Use the tcp mss command to configure the TCP MSS.
Use the undo tcp mss command to restore the default.
By default, the TCP MSS is 1460 bytes.
As the default MTU on an interface is 1500 bytes, and there are link layer cost and IP packet header, so
the recommended TCP MSS is about 1200 bytes.
Examples
# Set the TCP MSS to 300 bytes on Ten-GigabitEthernet 0/0.1.
<Sysname> system-view
[Sysname] interface Ten-GigabitEthernet 0/0.1
[Sysname-Ten-GigabitEthernet0/0.1] tcp mss 300

Parameters
time-value: Length of the TCP finwait timer in seconds, in the range 76 to 3,600.
Description
Use the tcp timer fin-timeout command to configure the length of the TCP finwait timer.
Use the undo tcp timer fin-timeout command to restore the default.
By default, the length of the TCP finwait timer is 675 seconds.
The actual length of the finwait timer is determined by the following formula:
Actual length of the finwait timer = (Configured length of the finwait timer – 75) + configured length of
the synwait timer
Related commands: tcp timer syn-timeout, tcp window.
Examples
# Set the length of the TCP finwait timer to 800 seconds.
<Sysname> system-view
[Sysname] tcp timer fin-timeout 800
