4. Refer to the following diagram, where a switch with ports 1 to 24 is connected to devices with MAC addresses \( \mathrm{A} \) to \( \mathrm{H} \). Assume that the forwarding table is initially empty and that the following sequence of transmissions occurs (each is a one-way frame transmission and there is no timeout of Forwarding Table entries during this time): [1] Device A transmits a frame to device \( E \) [2] Device \( E \) transmits a frame to device \( A \) [3] Device \( D \) transmits a frame to device \( G \) [4] Device \( \mathrm{E} \) transmits a frame to device \( \mathrm{H} \) [5] Device \( G \) transmits a frame to device D [6] Device \( \mathrm{H} \) transmits a frame to device \( \mathrm{E} \) Assume that the forwarding table is initially empty and that the following sequence of transmissions occurs (each is a one-way frame transmission and there is no timeout of Forwarding Table entries during this time): [1] Device \( A \) transmits a frame to device \( E \) [2] Device \( E \) transmits a frame to device \( A \) [3] Device D transmits a frame to device \( G \) [4] Device \( \mathrm{E} \) transmits a frame to device \( \mathrm{H} \) [5] Device G transmits a frame to device D [6] Device \( \mathrm{H} \) transmits a frame to device \( \mathrm{E} \) a. (6 pts) For each frame transmission, list all switch port(s) on which the frame is sent out. Note: this will never include the port on which the switch receives the frame. You should do these in order (from [1] to [5]) and keep track of how the Forwarding Table changes with each frame transmission. For example, the Forwarding Table is empty when frame [1] is received, but then the Forwarding Table is updated from frame [1], so it is not empty when frame [2] is received, then it is updated from frame [2] before frame [3] is received, etc. The contents of your forwarding table will be entered in part \( b \). i. ii. iii. iv. v. vi. b. (5 pts) Show the contents of the Forwarding Table after all six frame transmissions have completed (should be 5 rows). Each line of the Forwarding Table will have a MAC Address (A thru \( \mathrm{H} \) ) and a Port (1 thru 8).
