to top in multiples of four, starting with zero; for example, 0, 4, 8, 12, and so on. When a breakout cable is
installed, the resulting four 10GbE ports are numbered with the remaining numbers. For example, 40GbE
port 0 contains 10GbE ports 0, 1, 2, and 3; 40GbE port 4 contains 10GbE ports 4, 5, 6, and 7.
Line card 0 consists of ports 0 to 143; line card 1 consists of ports 0 to 191; line card 2 consists of ports 0
to 191.
