Managing Ethernet MicroLAN Switches

Packets

Use the text box in this field to determine the total number of packets (including all errors except collisions) that must be processed by the repeater, board, or port

within the user-specified time before an alarm is triggered. Allowable values are 1 to Ý 4 billion (232-1).

Broadcast Packets

Use the text box in this field to determine the number of broadcast packets that must be processed by the repeater, board, or port within the user-specified time before an alarm limit is reached. Allowable values are 1 to Ý 4 billion (232-1).

% Errors of Type

Use the text box in this field to determine what percentage of packets received by the repeater, board, or port within the specified time interval can be errors of the selected type or types before an alarm is triggered. Allowable values are one to 100; percentages will be calculated based on the number of error packets of all types selected (all those with an check in their check box). Again, a repeater-level alarm will count all selected error types received by the repeater channel; a port-level alarm will count only selected error types received by the individual port. (Remember, on an Ethernet MicroLAN Switch, a board is equivalent to a repeater channel.)

You can select any combination of the following error types:

CRC Errors

If this check box is selected, all packets with Cyclical

 

Redundancy Check (CRC) errors will be included in

 

calculating the overall percentage of errors.

Framing Errors

If this check box is selected, all misaligned packets will

 

be included in calculating the overall percentage of

 

errors. A misaligned packet is one with a non-integral

 

number of bytes; these are also sometimes referred to as

 

alignment errors.

Runts

If this check box is selected, the number of runt packets

 

will be included in calculating the overall percentage of

 

errors. A runt packet is one that is less than the minimum

 

Ethernet frame size of 64 bytes.

OOW Collisions

If this check box is selected, all collisions out of the

 

standard collision window (51.2 μs) will be included in

 

calculating the overall percentage of errors.

 

Out-of-window collisions are typically caused by faulty

 

network design.

Giants

If this check box is selected, the number of giant packets

 

will be included in calculating the overall percentage of

 

errors. A giant packet exceeds the maximum Ethernet

 

frame size of 1518 bytes (excluding the preamble).
