Rmon - ZyXEL Communications XS3800-28 Cli Reference Manual

75.1 RMON Overview
Similar to SNMP, RMON (Remote Network Monitor) allows you to gather and monitor network traffic.
Both SNMP and RMON use an agent, known as a probe, which are software processes running on
network devices to collect information about network traffic and store it in a local MIB (Management
Information Base). With SNMP, a network manager has to constantly poll the agent to obtain MIB
information. The probe on the Switch communicates with the network manager via SNMP.
RMON groups contain detailed information about specific activities. The following table describes the
four RMON groups that your Switch supports.
