mpls oam l2vc loss-measure oam-packet loss-ratio

Function

The mpls oam l2vc loss-measure oam-packet loss-ratio command configures alarm thresholds on a PW for the OAM packet loss ratio.

By default, the alarm threshold for the OAM packet loss ratio is 0.

Format

mpls oam l2vc loss-measure oam-packet loss-ratio threshold1 threshold1-value threshold2 threshold2-value peer-ip peer-ip vc-id vc-id vc-type vc-type

mpls oam l2vc loss-measure oam-packet loss-ratio { threshold1 threshold1-value | threshold2 threshold2-value } peer-ip peer-ip vc-id vc-id vc-type vc-type

Parameters

Parameter	Description	Value
threshold2 threshold2-value	Sets alarm threshold 2.	The value is an integer ranging from 0 to 100, in percentage.
peer-ip peer-ip	Specifies the destination IP address of a PW.	The value is in dotted decimal notation.
vc-id vc-id	Specifies the PW ID.	The value is an integer ranging from 1 to 4294967295.
vc-type vc-type	Specifies the type of a remote L2VC.	Encapsulation types supported: Other encapsulation types: cep: This encapsulation type is used for CEP services. ethernet: This encapsulation type is used when Ethernet packets do not carry VLAN information. ip-interworking: This encapsulation type is used for interworking between Huawei devices. ip-layer2: This encapsulation type is used for interworking between Huawei devices and non-Huawei devices. vlan: This encapsulation type is used when Ethernet packets carry VLAN information.
threshold1 threshold1-value	Sets alarm threshold 1.	The value is an integer ranging from 0 to 100, in percentage.

Usage Guidelines

Usage Scenario

When configuring OAM packet loss ratio detection on a PW, you can run the mpls oam ingress loss-measure oam-packet loss-ratio command to configure alarm thresholds. If the detected packet loss ratio exceeds a specified alarm threshold, an alarm is reported.

Two alarm thresholds can be configured. If the packet loss ratio exceeds alarm threshold 1 but does not reach alarm threshold 2, alarms are reported based on alarm threshold 1. If the packet loss ratio exceeds alarm threshold 2, alarms are reported based on both alarm thresholds 1 and 2.

Alarm threshold 1 can be set to a small value, and its associated alarms are informational only.

Alarm threshold 2 must be set to a value greater than alarm threshold 1, and its associated alarms must be cleared.

Configuration Impact

After the mpls oam bidirectional-tunnel loss-measure oam-packet loss-ratio command is run, the system detects the packet loss ratio. If the packet loss ratio exceeds a specified alarm threshold, SD1-NEAR or SD2-NEAR alarms are reported. When an alarm is generated, APS is triggered on the protection ring. After the alarm is cleared, an APS switchback is triggered.

Precautions

You must configure alarm thresholds based on the actual link status.

Example

# Set an alarm threshold to 50 for the OAM packet loss ratio on the ingress of a PW.
