 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.

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. You could then use Port Statistics

to help indicate the port from which the problem originates.

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.
