However, if you disable the ipforward-broadcast command, the ping packets can not be received by theVLAN-interface 2 of Switch B.Configuring TCPAttributesConfiguring TCPOptional ParametersTCP optional parameters that can be configured include:■ synwait timer: When sending a SYN packet, TCP starts the synwait timer. If noresponse packets are received within the synwait timer timeout, the TCPconnection is not successfully created.■ finwait timer: When the TCP connection is in FIN_WAIT_2 state, finwait timerwill be started. If no FIN packets are received within the timer timeout, the TCPconnection will be terminated. If FIN packets are received, the TCP connectionstate changes to TIME_WAIT. If non-FIN packets are received, the systemrestarts the timer from receiving the last non-FIN packet. The connection isbroken after the timer expires.■ Size of TCP receive/send bufferFollow these steps to configure TCP optional parameters:To do… Use the command… RemarksEnter system view system-view -
