Remote Monitoring (RMON)

Remote monitoring (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

Standards Compliance

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.
