Two ethernet switches sw1 and sw2 , Computer Engineering

Six machines H1, H2, ..., H6 are linked by two Ethernet switches SW1 and SW2 as given below. Both switches have four ports drawn. The port numbers are as indicated. Suppose the two switches are just turned on, so both switch tables are empty. Give the content of the switch tables at SW1 and SW2 after the following transmissions: 

 

(1) H1 sends a frame to H2; 

(2) H3 sends a frame to H5; 

(3) H4 sends a frame to H2;  

(4) H6 sends a frame to H3; 

(5) H5 sends a frame to H6. 

 

Use H1 to H6 to show the MAC addresses in your answer. Ignore the time stamp in every entry. Suppose no table entry expires. You do not have to list the table content after every transmission.
