function.
RMON is the internationally recognized and approved standard for
detailed analysis of shared Ethernet and Token Ring media. It ensures
consistency in the monitoring and display of statistics between different
vendors.
RMON’s advanced remote networking capabilities provide the tools
needed to monitor and analyze the behavior of segments on a network.
In conjunction with an RMON agent, RMON gathers details and logical
information about network status, performance, and users running
applications on the network.
An RMON agent is a probe that collects information about segments,
hosts, and traffic, and sends it to a management station.
The network administrator uses software tools to view the information
collected by the RMON agent on the management station.
Avaya P120 SMON User Guide1
RMON has two levels:
•RMON I analyzes the MAC layer (Layer 2 in the OSI seven-layer
•RMON II analyzes the upper layers (Layers 3 and above).
RMON is an industry standard that Avaya Inc. and other companies have
adopted in their network management applications. SMON takes the
RMON standard and extends it to the switching environment.
What is SMON
SMON is an extension of the RMON standard. SMON adds to the
monitoring capabilities of RMON in the following ways:
•It provides additional tools and features for monitoring in the

model).
switch environment.
•It provides a global view of traffic flow in a network with multiple
switches.
Device SMON extends RMON I for the MAC layer, and AnyLayer SMON
extends RMON II for the network layer and above. SMON monitoring
collects and displays data in real-time.
Using SMON monitoring, you can get:
•A global view of traffic for all switches on the network.
•An overall view of traffic passing through a specific switch.
•Detailed data about the hosts transmitting packets through a
switch.
•An analysis of traffic passing through each port connected to a
switch.
•A view of traffic between various hosts connected to a switch.
Overview of SMON
SMON is an RMON-compliant network management suite that
implements the SMON extensions to RMON. SMON works with the other
components of Avaya MultiService Network Manager to provide a full
spectrum of in-depth monitoring of switch traffic and network
performance.
Avaya P120 SMON User Guide2
Chapter 1
SMON consists of a software console application on a workstation and
remote monitoring probes in network devices that support SMON.
The SMON console communicates constantly with the SMON devices on
your network. The console uses the SNMP protocol to gather information
from the devices. SMON provides a suite of powerful graphic display tools
to view this information.
SMON gives you detailed analysis of the traffic flow on your switched
network, from a global view down to a specific host, and from total MAC
layer traffic down to a specific application protocol - all in real-time.
In addition, SMON allows you to set alarms based on traffic thresholds.
When an alarm is triggered, a trap can be sent to the device’s manager
and the event that triggered the alarm can be entered in SMON’s Event
Log.
SMON Devices
SMON provides monitoring capabilities for Avaya Inc’s network devices
that support the SMON extensions of the RMON standard.
Filtering Options
SMON tools provide different methods of filtering the information
displayed on the screen. These method include:
•Specific filtering
•TopN filtering
For information on how to use filters, refer to Appendix A, SMON Dialog
Boxes.
Specific
Filtering
TopN
Filtering
Specific filtering options provide the ability to specify the switches,
VLANs, or ports for which you want to view SMON information.
TopN filtering provides the ability to filter information based on the
amount of a particular type of traffic being monitored. When using TopN
filtering, specify the number of switches, VLANs, or ports for which you
want to view SMON information. Then select a statistic which will be
used as the basis for the filtering.
Using TopN filtering you can, for example, view information on only the
top 5 most active ports, or on the 8 switches generating the most error
traffic.
3Avaya P120 SMON User Guide
T opN filtering is powerful in that it allows you to focus on the information
that is important to you.
Device SMON Tools
The Device SMON tools for Avaya P120 Devices include:
•Switch Statistics - Detailed information on traffic passing
through the switch fabric.
•VLAN Statistics - Detailed information on switch traffic
associated with a VLAN.
•Port Statistics - Detailed information on port traffic to help
determine the precise cause of a problem.
•Alarms and Events - Notification of user defined Events that
help monitor a rise or fall of the rate of specified packets on
selected ports.
SMON Overview
Switch Statistics Overview
The Switch Statistics tool provides details of the traffic passing through
the switch fabric and allows you to detect problems on the switch. Once a
problem has been detected, you can use VLAN or Port Statistics to
determine more precisely the cause of the problem.
The display includes two sections:
•Pie charts and gauges showing traffic breakdown.
•A traffic graph that describes the characteristics of the traffic
passing through the device.
You can use the Switch Statistics tool for the following purposes:
•Gaining an overall view of the switched traffic over a specific time
period. This can help in discovering problems and analyzing traffic
trends.
•Discovering whether the device is being utilized efficiently or not.
•Monitoring the load distribution among VLANs.
•Detecting a large number of broadcast messages sent. This indicates
there may be a problem with a station on the network.
Avaya P120 SMON User Guide4
Chapter 1
•Treating any variable with abnormal behavior as an issue that
should be investigated further using other SMON tools.
In general, the Switch Statistics tool can help you spot problems that only
become apparent from a high-level view over time. By periodically
viewing Switch Statistics, you can detect normal and abnormal behavior
of the specific switch configuration.
SMON collects and displays all information in real-time. In addition,
information collected during a session can be saved in a report.
Port Statistics Overview
The Port Statistics tool measures the traffic travelling through each port
on the selected device. For each port, SMON summarizes the traffic, such
as packets into the device and packets from the device. You can sort by
port name or by any of the packet types. You can see, for example, the
ports generating the most errors.
If you notice that a particular port displays a disproportionate amount of
errors, this may suggest that a device connected to the port is responsible
for the problem.
You select the most active ports by using a rate base. SMON measures the
rate base for all the ports to find the most active ports and then displays
these ports and their statistics. This process is called Port TopN.
Using the Port Statistics tool in conjunction with VLAN Statistics and
Switch Statistics makes it straightforward to discover the cause of a
problem. For example, using Switch Statistics you may discover that there
are too many errors on a specific switch. Y ou could then use Port Statistics
to help indicate the port from which the problem originates.
VLAN Statistics Overview
The VLAN Statistics tool measures the switched traffic travelling through
VLANs on the selected switch. A VLAN consists of stations connected
logically rather than physically. A VLAN can be used, for example, to
distribute network resources by department, even if the department’s
stations are not all located in the same area. Therefore, a VLAN can
incorporate stations from different devices.
By comparing the load of each VLAN you can discover which VLANs are:
•Utilizing their full capacity.
•Under capacity.
5Avaya P120 SMON User Guide
•Over-extended and probably causing a degradation in performance
to the users.
VLAN Statistics represents the information as a horizontal bar chart. Using
this tool in conjunction with Port Statistics and Switch Statistics makes it
straightforward to discover the cause of a problem. For example, using
VLAN Statistics you may discover that there are too many broadcast
errors on a specific VLAN. You could then use Port Statistics to help
indicate from which port the problem originates.
Alarms and Events Overview
The Alarms and Events tool reports when a specified counter on selected
ports, or on a device, cross user defined thresholds. The Alarm Wizard
provides a simple method for defining upper and lower thresholds of a
counter on selected ports or on the device. This definition of the
thresholds is an Alarm.
An Event is the crossing of a defined threshold in the direction it was
defined. For example, a Rising Event is when the rate of a specified
counter on a selected port rises above the defined Rising (upper)
Threshold. A Falling Event is when the rate of a specified counter on a
selected port falls below the defined Falling (lower) Threshold.
SMON Overview
The following figure shows the scheme used to generate Events.
Figure 1-1. Events Overview
Counter
Rate
Rising Threshold
Falling Threshold
u
- Rising Event
- Falling Event
Time
Avaya P120 SMON User Guide6
Chapter 1
The first Event is a Rising Event, caused by the counter rate rising above
the Rising Threshold. The second Event is a Falling Event, caused by the
counter rate falling below the Falling Threshold. The third Event is a
Rising Event. Note, that although the rate falls below the Rising Threshold
and then rises above it again, no Event is generated. A new Rising Event
can only be generated after the rate falls below the Falling Threshold.
Similarly, after the fourth Event, although the rate rises above the Falling
Threshold and then falls below it again, no Event is generated. A new
Falling Event can only be generated after the rate rises above the Rising
Threshold.
If you want to be informed of the rise or fall of the rate of a particular type
of packet on a port, you could use the Alarm Wizard to define thresholds
for the packet type on the port. You co uld then specify whethe r an Even t
causes a trap to be sent to the device’s manager, or is listed in SMON’s
Device Event Log, or both.
If you suspect a problem on a port, you can use Alarms and Events to
notify you when a problem occurs. You could then use the Port History
tool to identify the duration and frequency of the problem. This can help
you locate the cause of the problem.
