Overview
Devices can either function on their own, or they can be connected into a stack of devices in
various stacking modes (see
).
By default, a device is always stackable, but has no port configured as a stack port. All the
ports in the devices are configured as network ports by default. A device without any stack
port can be thought of as the master device in a stack of only itself or as a standalone device.
To stack two or more devices, configure the desired network ports as stack ports in the devices
and connect the devices with the resulting stack ports in a ring or chain topology.
The devices (units) in a stack are connected through stack ports. These devices are then
collectively managed as a single logical device. In some cases, stack ports can become
members in a stack of Link Aggregation Groups (LAGs) increasing the bandwidth of the stack
interfaces. See
