RMON Monitoring Group Functions and Commands
RMON (Remote Network Monitoring) provides comprehensive network fault diagnosis, planning,
and performance tuning information and allows for interoperability between SNMP management
stations and monitoring agents. RMON extends the SNMP MIB capability by defining additional
MIBs that generate a much richer set of data about network usage.
These MIB “groups” each gather
specific sets of data to meet common network monitoring requirements.
Table 11-5 lists the RMON monitoring groups supported on Matrix Series devices, each group’s
function and the elements it monitors, and the associated configuration commands needed.
