Network Monitoring

This section is divided into three main areas: Statistics, Address Table, and
Applications. In addition, this section contains secondary windows.

Statistics

This section contains descriptions and illustrations of the following windows:

Port Utilization

Port Error Packets

Port Packet Analysis

Port Utilization

The switch module can display the utilization percentage of a specified port in the
following window.

The information on this window is described as follows:

Tx/sec

The rate at which the given port is transmitting packets, in packets per
second.

Rx/sec

The rate at which the given port is receiving packets, in packets per
second.

% Utilization

The percentage utilization of the available bandwidth of the given port.

Port Error Packets

The Web Manager enables various packet statistics to be viewed as either a line
graph or a table.

The Port Error Packet window contains the following information:
