Table 391 Configure router forwarding redirect packets
Operation
Configure router forwarding redirect packets
Disable router forwarding redirect packets
By default, router forwarding redirect packets is enabled.
4 Configure Router Receiving/Forwarding Source Route Packets
The following configurations should be made in system view.
Table 392 Configure router receiving/forwarding source address route packets
Operation
Configure router receiving/forwarding source
address route packets
Disable router receiving/forwarding source address
route packets
By default, router receiving/forwarding source address route packets is disabled.
To configure TCP performance, carry out the following steps:
1 Configure TCP Header Compression
When small messages are transmitted on low-rate physical lines (such as PSTN),
the TCP header occupies an obviously larger portion in the messages. To raise
transmission efficiency, TCP header compression can be configured on this
interface. At present, TCP head compression can only be used on PPP links.
Perform the following task in interface view.
Table 393 Enable/disable TCP header compression
Operation
Enable TCP/IP VJ header compression
Disable TCP header compression
TCP header compression is disabled in default status.
2 Configure TCP Timers
The following TCP timers can be configured:
Synwait timer: When a syn message is sent, TCP starts the synwait timer. If no
response message is received till synwait timeout, TCP connection will be
terminated.
Finwait timer: When the TCP connection status changes from FIN_WAIT_1 to
FIN_WAIT_2, the finwait timer is started. If no FIN message is received till the
finwait timer timeout, then TCP connection is terminated.
Size of the receiving and sending window for the connection-oriented Socket.
Perform the following task in system view.
