•Overview of SMON
•Device SMON Tools
•AnyLayer SMON Tools
What is RMON
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.
- A brief description of the RMON standard.
- A general description of SMON switch
monitoring technology.
- An introduction to SMON.
- The Device SMON tools and how they
function.
- The anylayer SMON tool and how
they function.
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 C460 SMON User Guide1
Chapter 1
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.
2Avaya C460 SMON User Guide
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.
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.
SMON Overview
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.
This section describes the following topics:
SMON Devices
SMON provides monitoring capabilities for Avaya Inc.’s network devices
that support the SMON extensions of the RMON standard.
For Avaya C460 Devices, SMON monitoring capabilities can be activated
by purchasing an SMON license from Avaya Inc.

Filtering Options
SMON tools provide different methods of filtering the information
displayed on the screen. These methods include:
•Specific Filtering
•TopN Filtering
Specific
Filtering
To pN
Filtering
Specific filtering options provide the ability to specify the switches,
VLANs, ports, hosts, subnets, or protocols 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, ports, hosts, subnets, or
protocols 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.
TopN filtering is powerful in that it allows you to focus on the information
that is important to you. For information on implementing TopN filtering,
refer to “Using the Define TopN Filter Dialog Box” on page 86

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.
SMON Overview
•Discovering whether the device is being utilized efficiently or not.
•Monitoring the load distribution among switches.
•Detecting a large number of broadcast messages sent. This indicates
there may be a problem with a station on the network.
•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. For more
information on using the Switch Statistics tool, refer to Chapter 3,
Switch Statistics.

Avaya C460 SMON User Guide5
Chapter 1
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 the
display 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. You could then use Port Statistics
to help indicate the port from which the problem originates. For more
information on using the Port Statistics tool, refer to Chapter 4,
Statistics.
Using Port
Extended Port Statistics Overview
The Extended Port Statistics tool measures the traffic travelling through a
specific port. SMON shows details of the traffic on the port, including
packet types and error types.
If you notice that a particular port displays a disproportionate amount of
errors, Extended Port Statistics can help you identify the type of error
occurring most often. This can help you pinpoint the cause of the
problem. For more information on using the Extended Port Statistics tool,
refer to Chapter 5,
Using Extended Port Statistics.
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.
6Avaya C460 SMON User Guide
By comparing the load of each VLAN you can discover which VLANs are:
•Utilizing their full capacity.
•Under capacity.
•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 the port from which the problem originates. For more
information on using the VLAN Statistics tool, refer to Chapter 6,
VLAN Statistics.
Alarms and Events Overview
SMON Overview
Using
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.
Avaya C460 SMON User Guide7
Chapter 1
The following figure shows the scheme used to generate events.
Figure 1-1. Events Overview
Counter
Rate
Rising Threshold
Falling Threshold
- Rising
u
Event
- Falling
Event
Time
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 could then specify whether an event
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. For more information on using the
Alarms and Events tool, refer to Chapter 7,
Using Alarms and Events.

Protocol Distribution Overview
Protocol Distribution provides you with details about the protocols routed
by an Avaya C460 routing module, and tracks the distribution of traffic
through the device among various network and application layer
protocols. Protocol Distribution collects all information in real-time, and
displays it in a variety of powerful and easy to use graphic formats.
Protocol Distribution stores all data recently collected from the device.
Protocol Distribution also allows you to save collected information in
reports. You can learn what is normal and abnormal behavior for your
specific network by viewing the reports and analyzing changes in your
network’s traffic. This can help you discover problems in your network
configuration. In general, the Protocol Distribution tool can help you see
things that become apparent over time from a high-level view. For more
information on C460 implementation of Protocol Distribution, refer to
Chapter 9,
Using Protocol Distribution and DSCP Statistics.
- Describes how the C460
DSCP Overview
Protocol Distribution for the Avaya C460 router modules includes
monitoring of DSCP tagged traffic. DSCP is an extension of IP which
provides a method of encoding QoS (Quality of Service) information in
the IP header of traffic. This enables you to change the priority of packets
to conform to standards for applications such as Voice over IP. Protocol
Distribution for Avaya C460 router modules provides graphical
representations of IP traffic with non-zero DSCP headers and IP traffic
with zero DSCP headers.
A DSCP value between 0 and 63 is added to the IP header of data packets.
For more information on the implementation of DSCP, refer to “Viewing
DSCP Statistics” on page 72.

results. For more information, refer to “Logarithmic Display” on page 78
.
Comparing the traffic graphs to the meters can often point you in the
right direction for locating a problem. For example, the pie chart may
show an abnormal amount of non-unicast packets, while the bandwidth
usage shown in the traffic graph has increased significantly. This may
suggest that one of the stations attached to the switch is generating the
non-unicast packets. By using VLAN Statistics you can locate the VLAN
where the problem originates. By using Port Statistics you can locate the
port to which the suspected station is attached.
* Note: All counters are in packets except counters that measure
bandwidth, which are in kilobits per second (Kbps).

Using The Port Statistics Window
The Port Statistics window is organized as follows:
•The title of the Port Statistics window shows the IP address of the
device.
•The X axis represents packets or percentage for Utilization.
•The Y axis represents ports and LAGs. Each row on the graph
corresponding to a port or LAG is labeled on the Y axis with a port
number, LAG number, or with the user defined name for a port.
•Link Aggregation Groups (LAGs) are displayed. These are a group
of ports serving as one logical link. When referencing the LAG’s
information box (place your cursor over the LAG bar), each port
within the LAG appears (refer to the figure below). In addition, the
speed of the LAG is the sum of the speed of all the ports within the
LAG.
