Managing Ethernet MicroLAN Switches

Runt Packets

The number of runt packets detected by the selected

 

repeater, board, or port. A runt frame is one that is less

 

than the minimum Ethernet frame size of 64 bytes.

Giant Packets

The number of giant packets detected by the selected

 

repeater, board, or port. A giant frame exceeds the

 

maximum Ethernet frame size of 1518 bytes (excluding

 

the preamble).

Algn. Errors

The number of misaligned packets detected by the

 

selected repeater, board, or port. Misaligned packets are

 

those which contain a non-integral number of bytes; they

 

can result from a MAC layer packet formation problem,

 

or from a cabling problem that is corrupting or losing

 

data. Alignment errors are also known as framing errors.

OOW Collns.

The number of collisions out of the standard collision

 

window (51.2 µs) experienced by the selected repeater,

 

board, or port. There are two conditions which can cause

 

this type of error to occur: either the network’s physical

 

length exceeds IEEE 802.3 specifications, or a node on the

 

net is transmitting without first listening for carrier sense

 

(and beginning its illegal transmission more than 51.2 µs

 

after the first station began transmitting).

Nothing

The Errors scale is not currently monitoring error

 

packets.

Configuring the Performance Graphs

1.Click on the Percent Load button; select the desired Load mode from the menu.

2.Click on the Frames button; select the desired Frames mode from the menu.

3.Click on the Total Errors button; select the desired Errors mode from the menu.

Once you have selected a new mode, it displays in its respective button, and the Performance Graph and statistics will refresh and begin to measure using the new mode. To stop monitoring and exit the window, click Cancel.

The Detail Button

The Detail button allows you to view traffic processed by the repeater channel, board, or port according to general frame status (good, errors, or collisions); it also allows you to view errors by type. When you click the Detail button, a separate window appears (Figure 5-5) that displays pie charts and statistics for both frame status and error type.
