default stacking ports, refer to
Configuring default ports on FCX devices on page 36.

Earlier generations of Brocade switches did not have ports exclusively dedicated to stacking. ICX 6610
devices include 4 ports on the back panel that are used entirely for this purpose. Note that these ports
cannot be used as data ports, even when stacking is not enabled.
There are the two 40-Gbps ports and two 4 x 10-Gbps ports arranged in two rows. By default, these
ports form stacked trunks. The figure below shows one stacked trunk on the top row between 1/2/1
and 1/2/2 and the second stacked trunk on the bottom row between 1/2/6 and 1/2/7.

To properly connect stacked trunk ports between devices, you must connect corresponding trucks
from one device to another. For example, the following figures show correctly connected ports. The
two stacked trunks can form either linear or ring topologies.
