RMON Monitoring Group Functions

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 15‐1 lists the RMON monitoring groups supported on SecureStack C3 devices, each group’s function and the elements it monitors, and the associated configuration commands needed.
