In the case when a switch fails, we need to grab the spare one, plug everything into it, duplicate the configuration, and light it up. This is a cold spare because it requires setup and configuration (either physical or in software; in this case both) before it can take over for the failed component.<br /> <br />A warm spare is then a piece of hardware that is all configured for use and just needs to be flipped on (again, either physically or in software) to start using it.<br /> <br />The third and most preferable mode of redundancy is to have hot spare components. When one component fails, the others automatically take over from it. The dead component is detected, and the transition happens without any user intervention.<br />Arun Manglickhttps://www.blogger.com/profile/03915326692989759515noreply@blogger.com
