Optional.
10 minutes by default.
Configuring IPv6 TCP properties
You can configure the following IPv6 TCP properties:
• 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 non-FIN packets are
received, the finwait timer is reset upon receipt of the last non-FIN packet and the connection is
terminated after the finwait timer expires.
• Size of the IPv6 TCP sending/receiving buffer.

Command Remarks
1. Enter system view.
system-view N/A
2. Set the IPv6 TCP timers.
• Set the synwait timer:
tcp ipv6 timer syn-timeout
wait-time
• Set the finwait timer:
tcp ipv6 timer fin-timeout
wait-time
Optional.
• By default:
• The synwait timer is 75 seconds.
• The finwait timer is 675
seconds.
3. Set the size of the IPv6 TCP
sending/receiving buffer.
tcp ipv6 window size
Optional.
8 KB by default.
Configuring IPv6 FIB load sharing
In the IPv6 FIB load sharing mode, the device can decide how to select equal cost multi-paths (ECMP) to
forward packets. The device supports the following load sharing modes:
• Load sharing based on the HASH algorithm—An algorithm based on the source IPv6 address and
destination IPv6 address is adopted to select an ECMP route to forward packets.
• Load sharing based on polling—Each ECMP route is used in turn to forward packets.
