22 Introduction
Configurable CX-4/Stacking Modules
This feature allows the stacking and CX-4 plug-in modules to be configured to either role (Ethernet or
Stacking). By default, the module will function according to its module ID. Upon changing the role of a
module, a reboot will be required for the change to take effect.
Non-stop Forwarding
This feature enables a stack to continue forwarding packets when the stack management unit fails due to
a power failure, hardware failure, or software fault.
