Setting the MSS Value for a TCP6 Connection

The minimum MSS value and maximum MSS value can be configured for TCP6 connections.

Context

Setting a minimum MSS value for a TCP6 connection defines the smallest TCP6 packet size, preventing DoS attacks caused by packets with small MSS values.

Setting a maximum MSS value for a TCP6 connection defines the largest TCP6 packet size, allowing TCP6 packets to be successfully forwarded by intermediate devices when no MTU is available.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run tcp ipv6 min-mss min-mss-val

    A minimum MSS value is configured for a TCP6 connection.

  3. Run tcp ipv6 max-mss max-mss-val

    A maximum MSS value is configured for a TCP6 connection.

    The maximum MSS value configured using the tcp ipv6 max-mss command must be greater than or equal to the minimum MSS value configured using the tcp ipv6 min-mss command.

  4. Run commit

    The configuration is committed.
