RPM Redundancy

The current version of Dell Networking OS supports 1+1 hitless route processor module (RPM)
redundancy.
The primary RPM performs all routing, switching, and control operations while the standby RPM monitors
the primary RPM. In the event that the primary RPM fails, the standby RPM can assume control of the
system without requiring a chassis reboot.
This section contains the following sub-sections:
• Boot the Chassis with a Single RPM
• Boot the Chassis with Dual RPMs
• Automatic and Manual RPM Failover
• Support for RPM Redundancy by Dell Networking OS Version
• RPM Synchronization
