Figure 18-3. Using the redundancy force-failover rpm Command to Copy Software between RPMs
Specify an Auto-failover Limit
When a non-recoverable fatal error is detected, an automatic failover occurs. However, FTOS is
configured to auto-failover only three times within any 60 minute period. You may specify a different
auto-failover count and period using the command redundancy auto-failover-limit.
To re-enable the auto-failover-limit with its default parameters, in CONFIGURATION mode, use the
redundancy auto-failover-limit command without parameters.
Disable Auto-reboot
Prevent a failed RPM from rebooting after a failover using the command redundancy disable-auto-reboot
from CONFIGURATION mode.
Manually Synchronize RPMs
Manually synchronize RPMs at any time using the command redundancy synchronize full from EXEC

no redundancy sfm standby. There is sub-second packet-loss anytime an SFM is brought
online or taken offline. Use the command
show sfm all to determine the status of the SFMs on the RPMs.
