Usage Guidelines

Usage Scenario

When a TCP6 connection changes from FIN_WAIT_1 to FIN_WAIT_2, the TCP FIN-Wait timer is started. If the local device does not receive a packet with the FIN flag after the TCP6 FIN-Wait timer expires, the TCP6 connection is closed.

Precautions

If you run the tcp ipv6 timer fin-timeout command multiple times, only the latest configuration takes effect.

You are advised to use this command under the supervision of technical support personnel.
