SMON continuously monitors statistics for all available Switch Statistics
traffic variables, even those that are not currently selected. For
information on finding the 5 highest peaks of traffic, refer to “Using the
Find Top5 Peaks Dialog Box” on page 87.
The X axis of the graph represents time. The scale on the X axis can be
changed using the
Samples Per Screen
field in the Switch Options dialog
box. For more information, refer to “Using the Options Dialog Box” on
page 74.
The units of the Y axis for all variables are packets. The scale on the Y axis
depends on the maximum value among all of the variables. If the spread
of values is wide, the graphs of variables with small values may not be
visible. In this case, use the logarithmic traffic display to produce better
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).
TPkts In Total packets entering the switch.
Uncsts in Good unicast packets entering the switch.
