RMON is an industry-standard implementation that monitors network traffic by sharing network monitoring information. RMON provides

both 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 be

chosen by using alarms and events with standard management information bases (MIBs).

Implementation Information

Configure SNMP prior to setting up RMON.

For a complete SNMP implementation description, refer to

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 History

RMON implements the following standard request for comments (RFCs) (for more information, refer to the

Fault Recovery

RMON provides the following fault recovery functions.

Interface Down — When an RMON-enabled interface goes down, monitoring continues. However, all data values are registered as

0xFFFFFFFF (32 bits) or ixFFFFFFFFFFFFFFFF (64 bits). When the interface comes back up, RMON monitoring processes resumes.

A network management system (NMS) should be ready to interpret a down interface and plot the interface

performance 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.
