CHAPTER 17 RMON Configuration Use this menu item to look at and configure RMON (Remote Network Monitor) on a switch. 17.1 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 OLT), 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 RMON groups that your device supports. Table 113 Supported RMON Groups GROUP DESCRIPTION History Records network traffic information on a specified Ethernet port. Alarm Provides alerts when configured alarm conditions are met. Event Defines event generation and resulting actions to be taken based on an alarm. NetAtlas EPON Manager User's Guide 229
