IP performance configuration includes:
"Configuring TCP Attributes"
■
TCP attributes that can be configured include:
synwait timer: When sending the syn packets, TCP starts the synwait timer. If
■
response packets are not received before synwait timeout, the TCP connection
is terminated. The timeout of synwait timer ranges from 2 to 600 seconds and
it is 75 seconds by default.
finwait timer: When the TCP connection state turns from FIN_WAIT_1 to
■
FIN_WAIT_2, finwait timer is started. If FIN packets are not received before
finwait timer timeout, the TCP connection is terminated. The timeout of
finwait timer ranges from 76 to 3600 seconds and it is 675 seconds by default.
The receiving/sending buffer size of the connection-oriented socket is in the
■
range from 1 to 32 KB and is 8 KB by default.
Perform the following configuration in System view.
Table 58 Configure TCP attributes
Operation
Configure timeout time for the synwait timer
in TCP
Restore the default timeout time of the
synwait timer
Configure timeout time for the FIN_WAIT_2
timer in TCP
Restore the default timeout time of the
FIN_WAIT_2 timer
Configure the socket receiving/sending buffer
size of TCP
Restore the socket receiving/sending buffer
size of TCP to default value
After the above configuration, execute the display command in any view to
display the running of the IP performance configuration, and to verify the effect of
the configuration.
