Splitting a Daisy-Chained PE Stack
If you split a PE stack in a daisy-chain topology into two sub-stacks and each sub-stack has a PE uplink to the controlling
bridge, the C9010 detects the stack split and generates an alarm. System administrator intervention is required to diagnose and
correct the split condition; for example, check cable connections or reboot stack units to reactivate each PE stack.
