Chapter 6 IP Performance Configuration

6.1 IP Performance Configuration
IP performance configuration includes:
Configure TCP attributes
6.1.1 Configure 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
will be terminated. The timeout of synwait timer ranges 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 will be started. If FIN packets are not received before
finwait timer timeout, the TCP connection will be terminated. Finwait timer ranges
76 to 3600 seconds. By default, finwait timer is 675 seconds.
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.
Table 6-1 Configure TCP attributes
Configure synwait timer time for TCP connection
establishment
Restore synwait timer time for TCP connection
establishment to default value
Configure FIN_WAIT_2 timer time of TCP
Restore FIN_WAIT_2 timer time of TCP to default
value
Configure the Socket receiving/sending buffer size
of TCP
Restore the socket receiving/sending buffer size of
TCP to default value
By default, the TCP finwait timer is 675 seconds, the synwait timer is 75 seconds, and
the receiving/sending buffer size of connection-oriented Socket is 8K bytes.
