Configuring TCP6 Timers

Set two TCP6 timers to control the TCP6 connection time.

Two TCP6 timers are available:

SYN-Wait timer: When SYN packets are sent, the SYN-Wait timer starts. If response packets are not received before the SYN-Wait timer expires, the TCP6 connection is terminated. The SYN-Wait timeout period ranges from 2 to 600, in seconds, and the default value is 75 seconds.
FIN-Wait timer: When the TCP connection status changes from FIN_WAIT_1 to FIN_WAIT_2, the FIN-Wait timer starts. If FIN packets are not received before the FIN-Wait timer expires, the TCP6 connection is terminated. The FIN-Wait timeout period ranges from 76 to 3600, in seconds, and the default value is 675 seconds.

Perform the following steps on the router:

Run system-view
The system view is displayed.
Run tcp ipv6 timer syn-timeout interval
The SYN-Wait timeout period is configured for TCP6 connections.
Run tcp ipv6 timer fin-timeout interval
The FIN_WAIT_2 timeout period is configured for TCP6 connections.
Run commit
The configuration is committed.
