Port Statistics Overview

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. You 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.

Events OverviewThe 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 Accessing Device SMON 2 Device SMONThe Device SMON User Interface Figure 2-1.

Traffic Variables in Switch StatisticsComparing 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 Using Port Statistics 4 Port StatisticsSelecting Ports to Display Port Statistics Variables Figure 4-1.
