Planning 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 7550 and ICX 7650 devices. However, a stack can contain any combination of devices from the same product line, for example, any combination of ICX 7650 devices.
