2) Learning Switches - Basics. Consider the LAN below consisting of 10 computers connected by two self-learning Ethernet switches. At t=0 the switch table entries for both switches are empty. At t = 1, 2, 3, and 4, a source ends to a destination as shown below, and the destination replies immediately (well before the next time step). H F B 15 11 8 7 K 14 12 E D Switch 2 MAC addr interface TTL MAC addr interface TTL Switch 1 Assume that the following connections occur: t=1: C-> L (C has sent a frame to L and L has responded to C) t=2: K->H (K has sent a frame to H and H has responded to K) t=3: D-> A (D has sent a frame to A and A has responded to D) t=4: B -> F (B has sent a frame to F and F has responded to B) Find out how the two switch tables will be filled out and answer the questions below. The answer to the question below is given as a sample. Question At t=1, what is the source entry for switch 1? Format your answer as (letter, number) or 'n/a' Answer: At time t=1, (C,3) is added as an entry to switch table 1 So, your answer in the blank MUST be in this format (C,3) or n/a if no entry Question 10 At t=1, what is the destination entry for switch 1? N.B: Format your answer as (letter, number) or n/a Question 11 At t=1, what is the source entry for switch 2? N.B: Format your answer as (letter, number) or n/a 1 pts 1 pts Question 12 At t=1, what is the destination entry for switch 2? N.B: Format your answer as (letter, number) or n/a Question 13 At t=2, what is the source entry for switch 1? N.B: Format your answer as (letter, number) or n/a Question 14 At t=2, what is the destination entry for switch 1? N.B: Format your answer as (letter, number) or n/a 1 pts 1 pts 1 pts Question 15 At t=2, what is the source entry for switch 2? N.B: Format your answer as (letter, number) or n/a Question 16 At t=2, what is the destination entry for switch 2? N.B: Format your answer as (letter, number) or n/a Question 17 At t=3, what is the source entry for switch 1? N.B: Format your answer as (letter, number) or n/a 1 pts 1 pts 1 pts Question 18 At t=3, what is the destination entry for switch 1? N.B: Format your answer as (letter, number) or n/a Question 19 At t=3, what is the source entry for switch 2? N.B: Format your answer as (letter, number) or n/a Question 20 At t=3, what is the destination entry for switch 2? N.B: Format your answer as (letter, number) or n/a 1 pts 1 pts 1 pts Question 21 At t=4, what is the source entry for switch 1? N.B: Format your answer as (letter, number) or n/a Question 22 At t=4, what is the destination entry for switch 1? N.B: Format your answer as (letter, number) or n/a Question 23 At t=4, what is the source entry for switch 2? N.B: Format your answer as (letter, number) or n/a 1 pts 1 pts 1 pts Question 24 At t=4, what is the destination entry for switch 2? N.B: Format your answer as (letter, number) or n/a 1 pts
