1. Consider the organization of an advanced switch. The outer box has room for a total of 20 line-card slots. Each data plane (DP) line card supports 12 ports, and the DP requires an additional 25% line card redundancy. (a) If a 48-port switch is intended, how many line-card slots remain unused? (b) If we decide to maximize the usage of the device capacity by using up the full capacity of the switch box, what is the maximum numbers of the applicable switch ports and all line cards? (c) Following part (b), is there any unused line card slots left? If yes, what would you suggest doing with them? 1. Consider the organization of an advanced switch.
