• For the first device in the stack, ports (1/2/1, 1/2/2) are being used as stacked ports.
• 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. This is a stacked-port configuration, odd-numbered port to odd-numbered port.
• 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 ring stack 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.
