Administrator Guide

Using PE Console Commands
To debug an error condition in a PE stack, you can connect a console to the console port on the master unit and enter PE console
commands. Contact Dell Networking support for assistance. The supported PE console commands are described in the C9000 Series
Command-Line Reference Guide.
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.
