Planning to build a stack
Before you begin to build a stack, you should be familiar with supported stacking software requirements, topologies, and
recommendations.

Software requirements

All units in a stack must be running the same software version.
Maximum configuration file size for any stack is 1 MB.

Stack requirements

Stacks must contain devices of the same type or product line. For example, a stack cannot combine ICX 7150, ICX 7250, ICX 7450,
ICX 7650, ICX 7750, or ICX 7850 devices. However, a stack can contain any combination of devices from the same product line, for
example, any combination of ICX 7250 devices.
NOTE
A core stack for an 802.1br (SPX) configuration is a stack that contains only ICX 7750 devices or only ICX 7650 devices,
although the stack may contain different types of ICX 7750 or ICX 7650 devices. Refer to the Ruckus FastIron Campus
Fabric Configuration Guide for more information.

Ruckus stacking topologies

Ruckus stacking technology supports linear and ring topologies.
Although Ruckus stackable units may be connected in a simple linear topology, Ruckus recommends a ring topology because it
offers the best redundancy and the most resilient operation. Unicast switching follows the shortest path in a ring topology. When
the ring is broken, the stack recalculates the forwarding path and then resumes the flow of traffic within a few seconds.
In a ring topology, all stack members must have two stacking directions; however, in a linear topology, both end units use only
one stacking direction. A direction may be represented by a stacking port or a stacking trunk that contains multiple ports. A
stacking trunk provides better bandwidth and redundancy.
