The RMON Groups
The RMON agent runs on the DCM, and comprises a set of MIB groups. RFC
1757 defines the function and organization of these groups. Bay Networks
implements the following groups in its RMON agent:
• Ethernet Statistics
• History Control
• Ethernet History
• Host
• HostTopN
• Matrix
• Filter
• Packet Capture
• Alarm
• Event
RMON groups contain control and data tables. Control tables contain control
parameters that specify which statistics you want to access. You can view and
change many entries in a control table. Data tables contain statistics that the agent
obtains, and usually you can only view entries in these tables.
Some of the groups work together to provide a particular RMON function. For
example, the History Control group and the Ethernet History group together
provide the history capability in the RMON agent for the DCM.
The following sections indicate the function of each group and the tables that each
group defines. Refer to RFC 1757 for the following information:
• A list of all the parameters that appear in a control table
• The read/write status of a control parameter
• The default values for control parameters with read/write status
• A list of all the objects that appear in a data table
Ethernet Statistics Group
The Ethernet Statistics group records data that the DCM measures on network
interfaces. The DCM creates one entry for the Ethernet interface that it monitors
on a device and places the entry in the EtherStatsTable. The EtherStatsTable also
contains control parameters for this group.
