∙
For the second device in the stack, ports (2/2/1, 2/2/2 and 2/2/3, 2/2/4) are being used as stacked ports.
∙
There is a single physical connection between device 1 and device 2 in the stack, ports 1/2/1 and 2/2/1 (odd-numbered port to
odd-numbered port). This is a stacked-port configuration.
∙
There are two physical connections between device 2 and device 3 in the stack. Port 2/2/3 is connected to port 3/2/7 (odd-
numbered port to odd-numbered port) and port 2/2/4 is connected to 3/2/8 (even-numbered port to even-numbered port).
This is a stacked-trunk configuration.

In a ring stacking topology, there is an extra connection between the logical first and last devices, forming a "ring" or "closed-loop." The
closed-loop connection provides a redundant path for the stack link, so if one link fails, stack communications can be maintained.
