RPM Redundancy
Conguration
Displays the following information:
• which RPM is the preferred Primary on next boot (the redundancy
primary command)

Failover means that the running conguration and routing table are applied on
secondary RPM. Fast Failover means that the running conguration 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)
