Host Group
The Host group identifies hosts on the network by recording the source and
destination media access control (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
might want to rank the hosts by the number of errors they generate. Control
parameters for this group appear in the hostTopNControlTable, and data this
group generates appears 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 interfaces at
different addresses. This group’s control parameters, such as hosts, appear 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 what type of packets the Ethernet DCM should capture.
Filter control parameters, such as the minimum length of the packets to capture,
appear 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.
