Figure 7 Core-edge fabric (typical depiction)
.
Core-edge fabric topologies are typically depicted as shown in
Figure
7, but can also be depicted
hierarchically as shown in
Figure
8. Both figures represent the same physical implementation. How
a topology is logically represented can help you understand the potential performance of a core-edge
topology.

Core-edge fabric types
The number of ISLs between edge and core switches—typically expressed as a fan-in ratio, such as
7:1—characterizes the core-edge fabric types. The first number (7) indicates the number of edge
ports. The second number (1) indicates the number of ISLs used by the edge ports to connect to a core
switch in the fabric.
