About Remote Network Monitoring (RMON)

RFC 1757 is an extension of SNMP. It speciﬁes a standard MIB that deﬁnes both

parameters for recording statistics and the actual statistics themselves.

The purposes of RMON include

• Monitoring network performance

You can conﬁgure the DCM to continuously perform diagnostics and monitor

network performance. If a network failure occurs, the DCM can store

statistical information about the failure. The management stations can use this

information to investigate the cause of the failure.

• Detecting and reporting problems

You can conﬁgure the DCM to recognize and continuously check for error

conditions.

• Collecting information for problem solving

You can conﬁgure the DCM to give management stations information they

need to solve problems. For instance, the DCM can identify the hosts on a

network that generate the most trafﬁc or errors.

Refer to “RMON Implementa

tion Notes,” later in this chapter, for issues you

should consider when using an N11 DCM for RMON.

The RMON Groups

The RMON agent runs on the DCM, and comprises a set of MIB groups. RFC

1757 deﬁnes the function and organization of these groups. Bay Networks

implements the following groups in its RMON agent:

• Ethernet Statistics

• History Control

• Ethernet History

• Host

• HostTopN

• Matrix

• Filter

• Packet Capture
