You can configure the following TCP attributes of the Ethernet switch:
synwait timer: When a SYN packet is sent, TCP starts the synwait timer. If no
■
response packet is received before the synwait timer times out, the TCP
connection is terminated. The timeout time of this timer ranges from 2 seconds to
600 seconds and defaults to 75 seconds.
finwait timer: When the TCP connection status changes from FIN_WAIT_1 to
■
FIN_WAIT_2, the finwait timer is started. If no FIN packet is received before the
finwait timer times out, the TCP connection is terminated. The timeout time of this
timer ranges from 76 seconds to 3,600 seconds and defaults to 675 seconds.
The sizes of receiving and sending buffers of connection-oriented sockets, which
■
range from 1 KB to 32 KB and default to 8 KB.

Operation
Enter system view
Set the timeout time of the TCP
synwait timer
Set the timeout time of the TCP
finwait timer
Set the transceive buffer size of
the TCP socket
After the above IP performance configuration, you can execute the display
commands in any view to display the system operating status and thus verify the IP
performance configuration.
