Application-Layer Matrix Group
The alMatrix group gathers statistics about pairs of hosts conversing over
a monitored port based on protocol. (The RMON-2 network-layer matrix
group gathers statistics based on the network address).
This group features one control table and three data tables. The alMatrix
SD and alMatrix DS tables monitor traffic flows per conversation over
monitored ports. The control table and its data table collect TopN
statistics (reports describing hosts that top a list).
Probe Configuration Group Capabilities
The probeConfig group outlines a standard set of configuration
parameters for RMON probes. Currently, your system supports one object
in the probeConfig group, the probeCapabilities object. The function of
this object is to identify the RMON groups that the probe supports.
Management
Information
Base (MIB)
This section provides information on the Management Information Base
(MIB). A MIB is a structured set of data that describes the way that the
network is functioning. The management software, known as the
agent ,
gains access to this set of data and extracts the information it needs. The
agent can also store data in the MIB. The following topics are covered:
■
MIB Files
■
Compiler Support
■
MIB Objects
■
MIB Tree
■
MIB-II
■
RMON-1 MIB
■
RMON-2 MIB
■
3Com Enterprise MIBs
MIB II is implemented for the EME module, Layer 2 and Multilayer
Switching Modules, and the switch fabric module of the Switch 4007
system. See the
Part II in this guide
for information about using the MIB II
features that are implemented for the EME module.
