RMON Monitoring Group Functions
RMON(RemoteNetworkMonitoring)providescomprehensivenetworkfaultdiagnosis,
planning,andperformancetuninginformationandallowsforinteroperabilitybetweenSNMP
managementstationsandmonitoringagents.RMONextendstheSNMPMIBcapabilityby
definingadditionalMIBsthatgenerateamuchrichersetofdataaboutnetworkusage.
TheseMIB
“groups”eachgatherspecificsetsofdatatomeetcommonnetworkmonitoringrequirements.
Table 14‐1liststheRMONmonitoringgroupssupportedonSecureStackB3devices,eachgroup’s
functionandtheelementsitmonitors,andtheassociatedconfigurationcommandsneeded.
