1.6 Configuring IPv6 TCP Properties

The IPv6 TCP properties you can configure include:
synwait timer: When a SYN packet is sent, the synwait timer is triggered. If no
response packet is received before the synwait timer expires, the IPv6 TCP
connection establishment fails.
finwait timer: When the IPv6 TCP connection status is FIN_WAIT_2, the finwait
timer is triggered. If no packet is received before the finwait timer expires, the IPv6
TCP connection is terminated. If a FIN packet is received, the IPv6 TCP
connection status becomes TIME_WAIT. If other packets are received, the finwait
timer is reset from the last received packet and the connection is terminated after
the finwait timer expires.
Size of the IPv6 TCP sending/receiving buffer.
Follow these steps to configure IPv6 TCP properties:
Enter system view
Set the finwait timer of
IPv6 TCP packets
Set the synwait timer of
IPv6 TCP packets
Set the size of the IPv6
TCP sending/receiving
buffer

1.7 Configuring ICMPv6 Packet Sending

1.7.1 Configuring the Maximum ICMPv6 Error Packets Sent in an Interval

If too many ICMPv6 error packets are sent within a short time in a network, network
congestion may occur. To avoid network congestion, you can control the maximum
number of ICMPv6 error packets sent within a specified time, currently by adopting the
token bucket algorithm.
You can set the capacity of a token bucket, namely, the number of tokens in the bucket.
In addition, you can set the update period of the token bucket, namely, the interval for
updating the number of tokens in the token bucket to the configured capacity. One
token allows one ICMPv6 error packet to be sent. Each time an ICMPv6 error packet is
sent, the number of tokens in a token bucket decreases by 1. If the number of ICMPv6
error packets successively sent exceeds the capacity of the token bucket, subsequent
ICMPv6 error packets cannot be sent out until the number of tokens in the token bucket
is updated and new tokens are added to the bucket.
