12.3 RMON
RMON (Remote Monitoring) based on SNMP (Simple Network Management Protocol)
architecture, functions to monitor the network. RMON is currently a commonly used network
management standard defined by Internet Engineering Task Force (IETF), which is mainly used to
monitor the data traffic across a network segment or even the entire network so as to enable the
network administrator to take the protection measures in time to avoid any network malfunction. In
addition, RMON MIB records network statistics information of network performance and
malfunction periodically, based on which the management station can monitor network at any time
effectively. RMON is helpful for network administrator to manage the large-scale network since it
reduces the communication traffic between management station and managed agent.
RM ON Group
This switch supports the following four RMON Groups defined on the RMON standard (RFC1757):
History Group, Event Group, Statistic Group and Alarm Group.
