Remote Monitoring (RMON)RMON is an industry-standard implementation that monitors network traffic by sharing network monitoring information. RMON providesboth 32-bit and 64-bit monitoring facility and long-term statistics collection on Dell Networking Ethernet interfaces.RMON operates with the simple network management protocol (SNMP) and monitors all nodes on a local area network (LAN) segment.RMON monitors traffic passing through the router and segment traffic not destined for the router. The monitored interfaces may bechosen by using alarms and events with standard management information bases (MIBs).Topics:• Implementation Information• Fault RecoveryImplementation InformationConfigure SNMP prior to setting up RMON.For a complete SNMP implementation description, refer to Simple Network Management Protocol (SNMP).Configuring RMON requires using the RMON CLI and includes the following tasks:• Setting the rmon Alarm• Configuring an RMON Event• Configuring RMON Collection Statistics• Configuring the RMON Collection HistoryRMON implements the following standard request for comments (RFCs) (for more information, refer to the Standards Compliancechapter).• RFC-2819• RFC-3273• RFC-3434• RFC-4502Fault RecoveryRMON provides the following fault recovery functions.• Interface Down — When an RMON-enabled interface goes down, monitoring continues. However, all data values are registered as0xFFFFFFFF (32 bits) or ixFFFFFFFFFFFFFFFF (64 bits). When the interface comes back up, RMON monitoring processes resumes.NOTE: A network management system (NMS) should be ready to interpret a down interface and plot the interfaceperformance graph accordingly.• Device Down — When a device goes down, all sampled data is lost. But the RMON configurations are saved in the configuration file.The sampling process continues after the chassis returns to operation.• Platform Adaptation — RMON supports all Dell Networking chassis and all Dell Networking Ethernet interfaces.45778 Remote Monitoring (RMON)
