Cell Network—Trunk-Drop Topology
Switches are connected to each other to form a chain of switches in a trunk-drop topology (also known
as a cascaded topology). See
Figure 1-2.
• The connection between the Layer 3 switch and the first Layer 2 switch is very susceptible to
oversubscription, which can degrade network performance.
• There is no redundancy to the loss of a connection.
