access backup-check detect-interval

Function

The access backup-check detect-interval command configures the backup detection interval and number of detections on an interface.

The undo access backup-check detect-interval command cancels the configuration.

By default, the backup detection interval is 8 hours, total number of detections is 21, and number of detection failures is 14 on an interface.

This command is supported only on the NetEngine 8000 F1A.

Format

access backup-check detect-interval detect-interval detect-count detect-count fail-count fail-count

undo access backup-check detect-interval detect-interval detect-count detect-count fail-count fail-count

Parameters

Parameter	Description	Value
detect-interval detect-interval	Specifies a backup detection interval.	The value is an integer ranging from 0 to 24, in hours. The default value is 8h.
detect-count detect-count	Specifies the total number of detections.	The value is an integer ranging from 1 to 255. The default value is 21.
fail-count fail-count	Specifies the number of detection failures on an interface. In other words, the number of times that the system detects that no backup protection is configured on an interface.	The value is an integer ranging from 1 to 255. The default value is 14.

Parameter

Description

Value

detect-interval detect-interval

Specifies a backup detection interval.

The value is an integer ranging from 0 to 24, in hours. The default value is 8h.

detect-count detect-count

Specifies the total number of detections.

The value is an integer ranging from 1 to 255. The default value is 21.

fail-count fail-count

Specifies the number of detection failures on an interface. In other words, the number of times that the system detects that no backup protection is configured on an interface.

The value is an integer ranging from 1 to 255. The default value is 14.

Usage Guidelines

Usage Scenario

The system detects the number of users on interfaces at the interval specified by detect-interval. If no backup protection is configured on a physical interface (sub-interfaces included), an intra-board Eth-Trunk interface (sub-interfaces included), or an interface with access response delay based on odd and even MAC addresses configured but load imbalance occurs (for example, access response delay based on odd and even MAC addresses fails to take effect due to an interface fault), a large number of users may fail to go online in case of a board fault. To configure the backup detection interval and number of detections on an interface, run the access backup-check detect-interval command. Then, an alarm is generated when the number of detection failures exceeds that specified by fail-count after the total number of backup detections performed reaches that specified by detect-count.

Precautions

This command is supported only on the admin VS.

The value of fail-count must be less than or equal to that of detect-count. Otherwise, the configuration fails.

Example

# Set the backup detection interval to 8 hours, total number of detections to 20, and number of detection failures to 15.
