Overview of chassis management redundancy

Some switches provide high availability through the use of hot-swappable, redundant management modules. In the event of a failure on the active management module, management module redundancy allows a quick and unattended transition from the active management module to the standby management module. The standby management module now becomes the active management module. Management module redundancy keeps the switch operating and reduces network downtime.

The advantages of redundant management are:

  • Maintaining switch operation if a hardware failure occurs on the active management module

  • Minimizing restart time caused by the failure of a management module

  • Hotswapping a failed management module with no downtime
