As a network
manager for a small/medium company, you are required to be aware of the health
of your LAN and help in taking decisions regarding its growth, security and
utilization rules by remotely monitoring some probes. You started your Remote monitoring
project by setting a number of objectives:1. The
current utilization percentage of the bandwidth and its trend.2. Create
history reports3. Know
which conversations (communicating hosts) are generating most traffic.4. Define
the settings to capture a specific type of frames.5. Set a
number of alarms raised by some critical states.6. Monitor
the traffic for some upper layer’s traffic.Task
1.a:For each
objective described in this task, the students are required to find the RMON
group and tables that will be pulled to get or set from it some parameters
as well as all objects that will be used. For some objectives, the student need
to set first the control table associated.Example:To determine
the traffic statistics with one host, we need to access the tables:
“hostControlTable” and “hostTable” in the Host group.The objects
that can be invocated:In
“hostControlTable”: hostControlTableSize and hostControlLastDeletedTime,
hostControlStatus,hostControlIndex.In
“hostTable” : hostAddress, hostCreationOrder and hostIndex.Task1.b:The students
need to give an example for the selected objects with a clear explanation.Example:In
“hostControlTable”:hostControlTableSize=10:
The number of hostEntries in the hostTable is 10. It is calculated by counting
distinct MAC addresses in the frames read.hostControlLastDeletedTime=0;is
the value of sysUpTime in the System group of mib-2 at which a row in the
hostTable was deleted. If no deletion was done than this number is set to 0.For all
other objects described in task a), the students need to provide an example and
its explanation.Task
1.c:The students
are required to conduct a comparison research about Open source tools for
Network monitoring and write a report based on it. The report must include the
features and limitations of each tool.Plagiarism
please its zero or 3%
