Planning to build a traditional stack
Before you begin to build a traditional stack, you should be familiar with supported stacking software requirements, topologies, and recommendations.
Software requirements
All units in a traditional stack must be running the same software version.
Maximum configuration file size for any stack is 1 MB.
Traditional stack requirements
Traditional stacks must contain devices of the same type or product line. For example, a traditional stack cannot combine ICX 7250, ICX 7450, and ICX 7750 devices. However, a traditional 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 traditional stack that contains only ICX 7750 devices, although the stack may contain different types of ICX 7750 devices. Refer to the
Brocade FastIron Campus Fabric Configuration Guide for more information.
