Usage
Information
If auto failover is disabled, enter the redundancy auto-failover-limit (without any 
parameters) to set auto failover to the default parameters (Count 3, Period 60 
minutes).Use the show redundancy command to view the redundancy status.
When you change one or both of the optional parameters, FTOS checks that the 
interval between auto failovers is more than five (5) minutes. If the interval is less, 
FTOS returns a configuration error message.

Usage
Information
Enabling this command will keep the failed RPM in the failed state. If there are two 
RPMs in the system, enabling this command prevents the failed RPM from becoming 
a working Standby RPM. If there is only one RPM in the system, the failed RPM will 
not recover — this will affect the system.
redundancy force-failover 
c e 
Force the secondary RPM to become primary RPM or force an SFM (on an E-Series 
chassis only) to become the standby SFM. This command can also be used to upgrade 
the software on one RPM from the other when the other has been loaded with the 
upgraded software. 
Syntax
redundancy force-failover 
{rpm | sfm [slot-number] }
rpm Enter the keyword rpm to disable auto-reboot of the failed RPM.
