Configuration
Use this menu item to look at and configure RMON (Remote Network Monitor) on a switch.
18.1 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. With RMON, the probe is located on a remote device
(the MSC), so a network manager (the EMS) does not need to constantly poll the probe for
information. The probe 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 IES supports.
18.2 History Config
Use this screen to view and configure RMON history configuration settings. To open this
