Huawei AR150 series - Setting the Aging Time of the PMTU; Setting the Size of the TCP Sliding Window

FIN-Wait timer expires, the TCP connection is closed. The value of the FIN-Wait timer
ranges from 76 to 3600, in seconds. The default value is 675s.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
tcp timer syn-timeout interval
The value of the SYN-Wait timer is set.
Step 3 Run:
tcp timer fin-timeout interval
The value of the FIN-Wait (FIN_WAIT_2) timer is set.

7.5.3 Setting the Aging Time of the PMTU
You can set a proper aging time of the path MTU (PMTU) to improve transmission efficiency
and network performance.
Context
When hosts on the same network communicate with each other, the MTU of the network is
important for the hosts. When hosts communicate with each other across multiple networks, it
is important to determine the minimum MTU on the network path because the MTUs of the link
layers on different networks are different. The minimum MTU on the network path is called the
PMTU.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
tcp timer pathmtu-age age-time
The aging time of the PMTU is set.
The aging time of an IPv4 PMTU is an integer ranging from 10 to 100, in minutes. The default
value is 0 minutes, that is, the PMTU never ages..
----End
7.5.4 Setting the Size of the TCP Sliding Window
You can set the size of the TCP sliding window, that is, the packet receive or transmit buffer
size of a connection-oriented socket, to improve network performance.
