Set Threshold Values - Dell Force10 C150 Configuration Manual

Set Threshold Values

The available pre-defined errors fall under two categories:
• Symbol Errors—a symbol is an (electrical or optical) pulse on the physical medium that represents
one or more bits. A symbol error occurs when a symbol degrades in transit so that the receiver is not
able to decode it. Gigabit and 10-Gigabit Ethernet have and expect symbol rate, also called Baud.
• Frame Errors—frame errors are frames with a bad CRC.
The available pre-defined errors are:
• Symbol Errors per Second—the number of symbol errors during a specified period exceeds a
threshold.
• Frame Errors per Second—the number of frame errors during a specified period exceeds a threshold.
• Frame Errors per Frame Period—the number of frame errors within the last N frames exceeds a
threshold.
• Frame Error Seconds per Time Period—an error second is a 1-second period with at least one
frame error. The Frame Error Seconds per Time Period error occurs when the number of error seconds
within the last M seconds exceeds a threshold.
Symbol Errors per Second
Task
Specify the high threshold value for
symbol errors, or disable the high
threshold.
Specify the low threshold for symbol
errors.
Specify the time period for symbol
errors per second condition.
