10.4.1.4 Host Group

The Host group creates and maintains a host table for the segment monitored. The Host MIB is very useful as it contains information and cumulative statistics for every discovered host such as:

Host MAC address

Good packets/octets received/transmitted Error packets transmitted

Broadcast packets transmitted Multicast packets transmitted

The information provided by the Host MIB is stored for each MAC host. If the error count or broadcast count rises sharply, it is relatively easy to isolate the culprit by host address.

Note: As this process consumes a lot of storage, the monitoring device may delete entries as needed based on the least recently used (LRU) entries first.

10.4.1.5 Host Top N Group

The Host Top N group provides a list of a given number of hosts that are

top-performers based on selected statistics. The user can select statistics from the base Statistics MIB, taken over an interval period specified by the management station. The number of such hosts to be selected is also specified by the management station.

For instance, you can specify viewing the top 5 senders, top 10 broadcast hosts, top 3 multicast hosts, etc. The Host Top N group can be particularly useful in isolating hosts that are a source of problems in the network.

10.4.1.6 Matrix Group

The Matrix group consists of tables that store statistics for a particular conversation between two addresses. New entries are appended as the monitoring device detects new conversations.

Three tables are maintained within the Matrix group:

Control table

Source-Destination table Destination-Source table

The Control table specifies the maximum number of entries to be captured and placed into the Source-Destination table and Destination-Source table. As more and more conversations are appended, resources will be recovered by deleting the least recently used entries.

The Source-Destination table captures statistical information about a conversation between two hosts and indexes that information from a transmitter-oriented perspective.

The following information is stored in this table:

Source MAC address Destination MAC address

Number of packets transmitted (including error packets) Number of octets transmitted

Number of errors transmitted
