Enable Error Monitoring The polling interval for Link Performance Monitoring is 100 milliseconds. Task Start (or stop) Link Performance Monitoring on an interface. Enable (or disable) support for Link Performance Monitoring on an interface. Command Syntax ethernet oam link-monitor on no ethernet oam link-monitor on Default: Enabled ethernet oam link-monitor supported no ethernet oam link-monitor supported Default: Enabled Command Mode INTERFACE INTERFACE 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. Command Syntax ethernet oam link-monitor symbol-period threshold high {symbols | none} Range: 1-65535 Default: None ethernet oam link-monitor symbol-period threshold low symbols Range: 0-65535 Default: 10 Command Mode INTERFACE INTERFACE 802.3ah | 99
