Packet Errors

The Web Manager allows port error statistics compiled by the Switch's management agent to be viewed as either a line graph or a table. Four windows are offered.

Received (RX)

The table displays the error packets received on the Switch. To view statistics for a specific port, select the port by using the Port pull down menu. The user may also use the real-time graphic of the Switch at the top of the web page by simply clicking on a port. To view this window, click Monitoring > Packet Errors >
