Chapter 9 IP Performance Configuration
9.1 IP Performance Configuration
IP performance configuration includes:
z Configure TCP attributes
9.1.1 Configure TCP Attributes
TCP attributes that can be configured include:
z synwait timer: When sending the syn packets, TCP starts the synwait timer. If
response packets are not received before synwait timeout, the TCP connection
will be terminated. The timeout of synwait timer ranges 2 to 600 seconds and it is
75 seconds by default.
z finwait timer: When the TCP connection state turns from FIN_WAIT_1 to
FIN_WAIT_2, finwait timer will be started. If FIN packets are not received before
finwait timer timeout, the TCP connection will be terminated. The timeout of finwait
timer ranges 76 to 3600 seconds and it is 675 seconds by default.
z The receiving/sending buffer size of connection-oriented Socket is in the range
from 1 to 32K bytes and is 8K bytes by default.
Perform the following configuration in System view.
