• Use the Application > Port Management screens (see
port management basic, bandwidth control, broadcast storm control, security, authentication
settings for specific devices.
• Use the Application > AP Manager screen (see

8.2 RMON Introduction
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 (ZyXEL Ethernet
Switches), so a network manager (the ENC) 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 the ZyXEL Ethernet Switches support.
