RMON and RMON2 MIB Groups

300018-A Rev. 00

B-3

The data collection function records periodic statistical samples from Ethernet

networks, for example, interval start time and number of packets. This function

places the statistical samples in the etherHistoryTable.

Host Group

The host group identifies hosts on the network by recording the source and

destination MAC addresses in good packets, and places the information in the

hostTable. This group also records the time it discovered a host on the network in

the hostTimeTable. The hostControlTable specifies control parameters, such as

which monitoring operations the Ethernet DCM performs, and contains some

information about the monitoring process.

HostTopN Group

The HostTopN group ranks hosts according to a statistic type. For example, you

can rank the hosts by the number of errors they generate. Control parameters for

this group are stored in the hostTopNControlTable, and data this group generates

is stored in the hostTopNTable. To use the HostTopN group, you must set up the

host group.

Matrix Group

The matrix group stores statistics for an interchange between hosts at different

addresses. This group’s control parameters, such as number of hosts, are stored in

the matrixControlTable. When the matrix group receives information from a good

packet, it places data in both the matrixSDTable and the matrixDSTable.

Filter Group

The filter group specifies the types of packets the Ethernet DCM can capture.

Filter control parameters, such as the minimum length of those packets, are stored

in the filterTable. Associated with each filter is a channel (a specific path along

which data flows). Control parameters in the channelTable define how and where

the filtered packets flow.
