Usage Information
The following describes the show redundancy command shown in the following example.
RPM Status
Displays the following information:
  • Slot number of the RPM.
  • Whether the RPM is Primary or Standby.
  • The state of the RPM: Active, Standby, Booting, or Offline.
  • Whether the link to the second RPM is up or down.
Displays the state of the second RPM, if present
RPM Redundancy Configuration
Displays the following information:
  • which RPM is the preferred Primary on next boot (the redundancy primary command)
  • the data sync method configured (the redundancy synchronize command)
  • the failover type (you cannot change this type; it is software-dependent). Hot Failover means that the running configuration and routing table are applied on secondary RPM. Fast Failover means that the running configuration is not applied on the secondary RPM until failover occurs, and the routing table on line cards is cleared during failover.
  • the status of auto booting the RPM (the redundancy disable-auto-reboot command)
  • the parameter for auto failover limit control (the redundancy auto-failover-limit command)
RPM Failover Record
Displays the following information:
  • RPM failover counter (to reset the counter, use the redundancy reset-counter command)
  • the time and date of the last RPM failover
  • the reason for the last RPM failover
Last Data Sync Record
Displays the data sync information and the timestamp for the data sync:
  • Start-up Config is the contents of the startup-config file.
  • Line Card Config is the line card types configured and interfaces on those line cards.
  • Runtime Event Log is the contents of the Event log.
  • Running Config is the current running-config.

This field only appears when you enter the command from the Primary RPM.
