Chapter 1 IPv6 Basic Configuration
Command
Function
ZXR10(config)#
ipv6 tcp synwait-time
<
wait-time
>
Sets the duration of attempting to
establish a TCP connection,
which affects the TCP
connections established
afterwards. Range: 30–80,
unit: second, default: 75
seconds.
ZXR10(config)#
ipv6 tcp window-size
<
wait-size
>
Sets the size of the window
for listening to TCP packets,
which is invalid for the existing
TCP connections. Range:
100–65535, unit: byte, default:
32768 bytes.
ZXR10(config)#
ipv6 tcp finwait-time
<
wait-time
>
Sets the duration of waiting to
close a TCP connection. Range:
300–675, unit: second, default:
675 seconds.
ZXR10(config)#
ipv6 tcp queuemax
<
packet-numbers
>
Sets the maximum TCP output
queue length, which is invalid for
the existing connections. Range:
5–50, unit: packets, default: 5
packets.
3.
Verify the configurations.
To improve transfer efficiency, IPv6 does not support fragmentation by intermediate
nodes. When the length of an IPv6 packet that is forwarded by the intermediate node
is greater than the MTU of the interface of the intermediate node, an ICMPv6 error
packet is sent to inform the source node of the Path MTU value (PMTU). In this way,
packets are fragmented on the source node.
Command
Function
ZXR10#
show ipv6 pmtu
Displays the MTU value learned
on the local device.
ZXR10#
show tcp6 brief
Displays brief information about
all TCPv6 connections.
ZXR10#
show tcp6 config
Displays information about
TCPv6 configuration parameters.
ZXR10#
show tcp6 statistics
Displays TCP layer statistical
parameters.
ZXR10#
show tcp6 tcb
<
tcb-index
>
Displays the TCPv6 connection
parameters of the specified TCB.
