trap-threshold symbol-error high-threshold low-threshold (system view)

Function

The trap-threshold symbol-error high-threshold low-threshold command sets an upper threshold, lower threshold, and detection interval for the Symbol error alarm.

The undo trap-threshold symbol-error high-threshold low-threshold command restores the upper threshold, lower threshold, and detection interval of the Symbol error alarm to the default values.

By default, the upper threshold of the Symbol error alarm is 1000, the lower alarm threshold is 100, and the detection interval is 10 seconds.

Parameters

Parameter	Description	Value
card cardid	Specifies the ID of a registered subcard.	-
high-threshold high-threshold	Specifies an upper alarm threshold.	The value is an integer in the range from 1 to 4294967295. The default value is 1000.
low-threshold low-threshold	Specifies a lower alarm threshold.	The value is an integer ranging from 1 to 4294967295. The default value is 100.
interval-second interval	Specifies a detection interval for Symbol error frames.	The value is an integer ranging from 1 to 65535, in seconds. The default value is 10.

Usage Guidelines

Usage Scenario

To set an upper threshold, lower threshold, detection interval for the Symbol error alarm, run the trap-threshold symbol-error high-threshold low-threshold command. After this configuration is performed, a device generates an alarm and sends it to an NMS only when the number of Symbol error frames sent or received by the device reaches the upper threshold for three consecutive detection intervals. The device sends a clear alarm to the NMS only when the number of Symbol error frames sent or received by the device falls below the lower threshold for three consecutive detection intervals.

Precautions

The configured thresholds take effect only when the Symbol alarm function is enabled. You can run the snmp-agent trap enable port symbol-error command to enable the Symbol alarm function on an interface.

The value of high-threshold must be greater than or equal to that of low-threshold.

In VS mode, this command is supported only by the admin VS.

Example

# On each interface of subcard 1 in slot 1, set the upper threshold of the Symbol error alarm to 1500, lower threshold to 150, and detection interval to 15 seconds.
