Parameters
high-factor high-factor-value: Specifies the upper bit error ratio calculation factor in the range of 1 to 99.
low-factor low-factor-value: Specifies the lower bit error ratio calculation factor in the range of 1 to 99.
Usage guidelines
With error code detection enabled, the device periodically samples and checks the packets sent and received by an interface and performs the following operations:
· When the interface is in lower bit error ratio status, the device uses the upper bit error ratio calculation factor to calculate a result. Then, the device compares the calculation result with the upper bit error ratio threshold to determine whether the interface is in upper bit error ratio status.
· When the interface is in upper bit error ratio status, the device uses the lower bit error ratio calculation factor to calculate a result. Then, the device compares the calculation result with the lower bit error ratio threshold to determine whether the interface is in lower bit error ratio status.
You can use this command to adjust the bit error ratio calculation factors to adjust the timeliness and reliability of the calculation results. A smaller calculation factor means a higher timeliness and lower reliability.
This command takes effect only when the link-quality crc-error bit-error-ratio or port ifmonitor crc-error bit-error-ratio command is executed.
Examples
# On Twenty-FiveGigE 1/0/1, set the upper bit error ratio calculation factor to 10 and lower bit error ratio to 50.

Parameters
bfd: Specifies BFD for transferring error code detection information.
lldp: Specifies LLDP for transferring error code detection information.
Usage guidelines
When an error code failure occurs on an interface, the error code status of the interface must be sent to the peer device. The device supports using BFD or LLDP for transferring the error code status of interfaces. When the device is connected to a third-party device, you can use this command to select a protocol for transferring error code information, so that the peer device can recognize the error code information.
To use LLDP for transferring error code detection information, make sure LLDP is enabled and LLDP operates in nearest bridge agent mode. For more information about LLDP, see LLDP configuration in Layer 2—LAN Switching Configuration Guide.
Examples
# Configure Twenty-FiveGigE1/0/1 to use LLDP for transferring error code detection information.
<Sysname> system-view
[Sysname] interface twenty-fivegige 1/0/1
[Sysname-Twenty-FiveGigE1/0/1] crc-error bit-error-ratio transfer-protocol lldp
This command takes effect only after LLDP is enabled both globally and on the interface.

Parameters
high-threshold high-value-coefficient high-value-power: Specifies the upper bit error ratio threshold, which is calculated by using the formula xE-y. The high-value-coefficient argument specifies the coefficient (x in xE-y) in the range of 1 to 9. The high-value-power argument specifies the power (y in xE-y) in the range of 1 to 7.
low-threshold low-value-coefficient low-value-power: Specifies the lower bit error ratio threshold, which is calculated by using the formula xE-y. The high-value-coefficient argument specifies the coefficient (x in xE-y) in the range of 1 to 9. The high-value-power argument specifies the power (y in xE-y) in the range of 1 to 7.
Usage guidelines
With this command executed on an interface, the device periodically samples, calculates, and detects the packets received on the interface.
· If the bit error ratio exceeds the upper threshold, an error code failure occurs on the interface. Then, the link quality of the interface becomes LOW, and an error code event is reported. In this case, IGP (for example, OSPF and IS-IS) increases the cost for the link and recalculates the routes, so that IGP does not preferentially select the link and keeps off error code failures.
· If the bit error ratio drops below the lower threshold, the error code failure is cleared on the interface. Then, the link quality of the interface restores to GOOD, and an error code clearing event is reported. In this case, IGP restores the cost value for the interface and recalculates the routes, so that IGP can preferentially select the link again.
The bit error ratio is calculated by using the formula xE-y, where E=10.
When an error code failure occurs on a Layer 3 Ethernet interface that is not assigned to any aggregation group, LSP switchover is also triggered in addition to link cost adjustment and IGP route recalculation.
Make sure the lower threshold is no greater than the upper threshold.
This command and the port ifmonitor crc-error or port ifmonitor crc-error bit-error-ratio command are mutually exclusive.
Examples
# Set the link quality detection parameters for Twenty-FiveGigE 1/0/1 as follows:

Parameters
high-threshold high-value-coefficient high-value-power: Specifies the upper bit error ratio threshold, which is calculated by using the formula xE-y. The high-value-coefficient argument specifies the coefficient (x in xE-y) in the range of 1 to 9. The high-value-power argument specifies the power (y in xE-y) in the range of 1 to 5.
low-threshold low-value-coefficient low-value-power: Specifies the lower bit error ratio threshold, which is calculated by using the formula xE-y. The high-value-coefficient argument specifies the coefficient (x in xE-y) in the range of 1 to 9. The high-value-power argument specifies the power (y in xE-y) in the range of 1 to 6.
trigger-lsp: Enables error code failures to trigger LSP switchover. Layer 2 Ethernet interfaces and Layer 2 aggregate interfaces do not support this keyword.
trigger-section: Enables error code failures to trigger section layer service protection.
Usage guidelines
With the trigger-lsp keyword specified, an error code failure occurring on an interface is reported to the upper-layer service module to switch traffic from the primary LSP to the secondary LSP. After the error code failure is cleared, traffic is switched back to the primary LSP.
With the trigger-section keyword specified, an error code failure occurring on an interface is reported to the interface management module to set the link layer protocol status of the interface to DOWN(Bit-error down). Then, the upper-layer service module associated with the interface triggers section layer service protection. After the error code failure is cleared, the link layer protocol status of the interface restores to UP and the upper-layer service module cancels section layer service protection.
The bit error ratio is calculated by using the formula xE-y, where E=10.
The requirements for the bit error ratio vary by device and service. Set the bit error ratio thresholds according to the network planning and device requirements.
This command and the link-quality command are mutually exclusive.
If you execute this command and the port ifmonitor crc-error command multiple times, the most recent configuration takes effect.
Examples
# Set the error code detection parameters for Twenty-FiveGigE 1/0/1 as follows:
· For the upper bit error ratio threshold, set the coefficient to 1 and the power to 4.
· For the lower bit error ratio threshold, set the coefficient to 1 and the power to 5.
