RMON
RMON (Remote Network Monitoring) is an industry standard specification that 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 18-1 lists:
• The RMON monitoring groups supported on Fixed Switch devices
• Each group’s function
• The elements it monitors
• The group’s associated commands
