Managing Ethernet MicroLAN Switches

Soft Errors

 

CRC Errors

Displays the total number of packets with CRC (Cyclical

 

Redundancy Check) errors that the repeater, board, or

 

port has received from the network. CRC errors occur

 

when packets are somehow damaged in transit.

Alignment Errors

Displays the total number of misaligned packets received

 

by the repeater, board, or port. A misaligned packet is

 

one that contains a non-integral number of bytes (that is,

 

any unit of bits less than a byte). Alignment errors are

 

also known as framing errors.

Runts

Displays the number of runt packets that the repeater,

 

board, or port has received from the network. A runt

 

packet is one that is less than the minimum Ethernet

 

frame size of 64 bytes.

NOTE

For more detailed deÞnitions of these statistics and information on the possible network conditions they represent, consult the Cabletron Systems Network Troubleshooting Guide, included with this package.

Using the Total and Delta Option Buttons

By using the Total and Delta option buttons located at the bottom of the Statistics windows, you can choose whether to view the total statistics count (Total) or the statistics count for the last polling interval (Delta).

To choose Total or Delta:

1.Click on the Total option button; after the completion of the current polling cycle plus one complete polling cycle, the window will display the total count of statistics processed since the most recent start-up of the Ethernet MicroLAN Module.

2.Click on the Delta option button; after the completion of the current polling cycle plus two more polling cycles, the window will display the count of statistics processed during the last poll interval. These counts will be refreshed after each polling interval.

The statistics windows use the polling interval you have set for the monitored device via

TIP the Device Management page of the Options window, which is launched from the Tools menu in the SPECTRUM Element Manager primary window menu bar. See your SPECTRUM Element Manager UserÕs Guide for more information on setting the Chassis Manager polling interval.
