After the above configurations, if you ping the subnet broadcast address (2.2.2.255) of VLAN-interface 

2 of Switch A on the host, the ping packets can be received by VLAN-interface 2 of Switch B. 

TCP optional parameters that can be configured include: 

z 

synwait timer: When sending a SYN packet, TCP starts the synwait timer. If no response packet is 

received within the synwait timer interval, the TCP connection cannot be created.  

z 

finwait timer: When a TCP connection is changed into FIN_WAIT_2 state, the finwait timer is 

started. If no FIN packets is received within the timer interval, the TCP connection will be 

terminated. If a FIN packet is received, the TCP connection state changes to TIME_WAIT. If a 

non-FIN packet is received, the system restarts the timer upon receiving the last non-FIN packet. 

The connection is broken after the timer expires.
