The accept-mismatch enable command enables the local end to receive packets without the AO option from the peer end.
The undo accept-mismatch enable command restores the default configuration.
By default, the local end does not receive the packets that do not carry the AO option when the peer initiates a TCP connection.
Usage Scenario
To ensure the security of a TCP connection, the local end does not receive the packets that do not carry the AO option when the peer end initiates a TCP connection by default.
If the peer end does not support the AO option in TCP packets, run the accept-mismatch enable command to enable the local end to receive packets without the AO option for a TCP connection initiated by the peer end to ensure that the TCP connection can be established.
