Alarm Limits

packets were collisions (15 collisions for every good packet). Therefore, the lower you set your threshold value, the lower the percentage of collisions per good packet you are allowing.

Remember, a repeater-level alarm will calculate the number of collisions per good packet based on all traffic received on the repeater channel; a board- or port-level alarm will make the calculation based on traffic on the specific board or port only.

Packets

Use the text box in this field to determine the number of good packets (excluding all errors) 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 1 to 100; percentages will be calculated based on the number of error packets of all types selected (all those with an X in their check box). Again, a repeater-level alarm will count all selected error types received by the repeater; a board- or port-level alarm will count all selected error types received by the individual board or port.

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.
