However, all datavalues are registered as 0xFFFFFFFF (32 bits) or ixFFFFFFFFFFFFFFFF (64 bits). When the interfacecomes back up, RMON monitoring processes resumes.Line Card Down—The same as Interface Down (see above).RPM Down, RPM Failover—Master and standby RPMs run the RMON sampling process in thebackground. Therefore, when an RPM goes down, the other RPM maintains the sampled data—the newmaster RPM provides the same sampled data as did the old master—as long as the master RPM had beenrunning long enough to sample all the data.NMS backs up all the long-term data collection, and displays the failover downtime from the performancegraph.Chassis Down—When a chassis goes down, all sampled data is lost. But the RMON configurations aresaved in the configuration file, and the sampling process continues after the chassis returns to operation.Platform Adaptation—RMON supports all Dell Force10 chassis and all Dell Force10 EthernetInterfaces.Note: A Network Management System (NMS) should be ready to interpret a down interfaceand plot the interface performance graph accordingly.
