Please explain frames and responds

Consider the following LAN structure. Initially the switch table in all switches is empty and we assume no aging out (i.e., TTL = ∞). Each number in parentheses is the interface number for each link for the switch. For example, switch S1 has four interfaces of (1), (2), (3), and (4). Also assume that the MAC address for every node is already known to every other node (so ARP does not need in this problem).

a) Suppose C sends a frame to I and I responds to C immediately. Show the switch table in S1, S2, S3, and S4, right after the communication between these two hosts.
