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,
Using Port
Statistics.
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.
