Specifing an Auto-failover Limit<br />

When a non-recoverable fatal error is detected, an automatic failover occurs. However, FTOS is<br />

configured to auto-failover only three times within any 60 minute period. You may specify a different<br />

auto-failover count and period using the command redundancy auto-failover-limit.<br />

To re-enable the auto-failover-limit with its default parameters, in CONFIGURATION mode, use the<br />

redundancy auto-failover-limit command without parameters.<br />

Disabling Auto-reboot<br />

Prevent a failed RPM from rebooting after a failover using the command redundancy disable-auto-reboot<br />

from CONFIGURATION mode.<br />

Manually Synchronizing RPMs<br />

Manually synchronize RPMs at any time using the command redundancy synchronize full from EXEC<br />

Privilege mode.<br />

Switch Fabric Module redundancy<br />

Switch Fabric Module Redundancy is supported only on platform: c<br />

Since the RPM on the C-Series also contains the switch fabric, even though the second RPM comes online<br />

as the standby, the switch fabric is active and is automatically available for routing. Change this behavior<br />

using the command redundancy sfm standby from CONFIGURATION mode. To bring the secondary<br />

SFM online, enter no redundancy sfm standby. There is sub-second packet-loss anytime an SFM is<br />

brought online or taken offline. Use the command show sfm all to determine the status of the SFMs on the<br />

RPMs.<br />

Online Insertion and Removal<br />

You can add, replace, or remove chassis components while the chassis is operating.<br />

This section contains the following sub-sections:<br />

RPM Online Insertion and Removal<br />

<strong>Force10</strong> systems are functional with only one RPM. If a second RPM is inserted, it comes online as the<br />

standby RPM, as shown in Figure 187.<br />
