Configuration Notes for FastIron Devices in a Traditional Stack

In a RUCKUS traditional stack system, a LAG may have port members distributed across multiple stack units. Both static and dynamic LAGs are supported.

The following notes apply to FastIron stackable devices that are part of a traditional stack:

• If a stack unit fails or is removed from the stack, its static LAG configuration becomes a reserved configuration on the Active Controller. Any remaining ports of the static LAG in the traditional stack continue to function.
• When a new stack unit is added to a traditional stack, the new unit receives the running configuration and LAG information, including a list of ports that are up and are members of a LAG, from the Active Controller.
• Before merging two traditional stack devices, make sure that there are no static LAGs configured between them, which may result in self-looped ports.
• When a traditional stack device with a static LAG partitions into multiple traditional stacks, loops and forwarding errors may occur. In these cases, user intervention is required to remove the loops.
• 10-Gbps links support up to 16 ports in a LAG for stackable units.
• You cannot configure a LAG between CB and PE ports in SPX stacks.
