A symbol error occurs when a symbol degrades in transit so that the receiver is notable 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 athreshold.• 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 athreshold.• Frame Error Seconds per Time Period—an error second is a 1-second period with at least oneframe error. The Frame Error Seconds per Time Period error occurs when the number of error secondswithin the last M seconds exceeds a threshold.Symbol Errors per SecondTask Command Syntax Command ModeSpecify the high threshold value forsymbol errors, or disable the highthreshold.ethernet oam link-monitor symbol-period thresholdhigh {symbols | none}Range: 1-65535Default: NoneINTERFACESpecify the low threshold for symbolerrors.ethernet oam link-monitor symbol-period thresholdlow symbolsRange: 0-65535Default: 10INTERFACESpecify the time period for symbolerrors per second condition.ethernet oam link-monitor symbol-period windowsymbolsRange: 1-65535 (times 1,000,000 symbols)Default: 10 (10,000,000 symbols)INTERFACE
