(Optional) Setting an MSS Value for MAP-E Services

The maximum segment size (MSS) value defined in TCP specifies the maximum length of a TCP packet to be sent without fragmentation. Two devices exchange SYN packets to negotiate the MSS value for a TCP connection to be established. If the size of packets for MAP processing is larger than a link MTU, the packets are fragmented. You can reduce the MSS value in TCP, which prevents a service board from fragmenting packets and helps improve MAP efficiency.

Prerequisites

If the size of packets for processing is larger than a link MTU, IPv6 packets are fragmented. You can reduce the MSS value in TCP, which prevents a service board from fragmenting packets and helps improve MAP efficiency.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run map-e instance instance-name [ id id ]

    The MAP-E instance view is displayed.

  3. Run map tcp adjust-mss mss-value

    An MSS value is set in TCP SYN and SYN ACK packets.

  4. Run commit

    The configuration is committed.
