The IEEE 802.1D specification recommends a maximum network diameter of 7 switches. The term ‘diameter' refers to the maximum number of switches a frame would have to travel to get from one end of the network to the other. A network diameter of 7 switches means that no two distinct switches can be more than seven hops away from each other. To understand this concept, consider the switched network illustrated in Figure 3-28 below:
