Version Compatibility between RPMs<br />

The system checks to ensure <strong>the</strong> high availability compatibility of <strong>the</strong> software images on <strong>the</strong> two RPMs.<br />

Images are compatible only if <strong>the</strong> first two digits of <strong>the</strong> version number match. If <strong>the</strong>y do not, an error<br />

message is displayed. View <strong>the</strong> loaded versions of <strong>FTOS</strong> on <strong>the</strong> RPMs using <strong>the</strong> command show<br />

redundancy (Figure 266).<br />

Second RPM online as standby<br />

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

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

using <strong>the</strong> command offline sfm standby. To bring <strong>the</strong> secondary SFM online, issue <strong>the</strong> online sfm<br />

standby command. There is traffic loss anytime an SFM is brought online or taken offline. Use <strong>the</strong><br />

command show sfm all to determine <strong>the</strong> status of <strong>the</strong> SFMs on <strong>the</strong> RPMs.<br />
