Configuring Y.1731 Functions in VLAN Networking

This section describes how to config Y.1731 functions including single-ended frame loss measurement, dual-ended frame loss measurement, one-way frame delay measurement, two-way frame delay measurement, AIS, and multicast MAC ping in VLAN networking.

Applicable Environment

As shown in Figure 1, the Y.1731 functions can be used to monitor links between the CEs:

Pre-configuration Tasks

Before configuring Y.1731 functions in VLAN networking, complete the following tasks:

Completing VLAN-related configurations on the peer MEPs
Completing CFM-related configurations on the peer MEPs and configuring the type of the peer MEPs as outward

Binding an MA to a VLAN: Binding an MA to a VLAN is a prerequisite for configuring single-ended frame loss measurement, dual-ended frame loss measurement, one-way frame delay measurement, or two-way frame delay measurement in VLAN networking.

Configuring Single-ended Frame Loss Measurement in VLAN Networking: In VLAN networking, CFM is enabled. CCMs are not used to monitor link connectivity, preventing them from using a lot of network bandwidth resources. If frame loss measurement needs to be performed for a link, single-ended frame loss measurement can be configured to monitor the quality of the link.

Configuring Dual-ended Frame Loss Measurement in VLAN Networking: In VLAN networking, CFM is enabled to monitor link connectivity. If accurate frame loss measurement needs to be performed for a link, dual-ended frame loss measurement can be configured to monitor the quality of the link.

Configuring One-way Frame Delay Measurement in VLAN Networking: In VLAN networking, the clock frequency between the two ends is synchronized and CFM is enabled to monitor link connectivity. If the unidirectional delay measurement needs to be performed for a link, one-way frame delay measurement can be configured to monitor the quality of the link.

Configuring Two-way Frame Delay Measurement in VLAN Networking: In VLAN networking, the clock frequency between the two ends are not synchronized and CFM is enabled to monitor link connectivity. If the bidirectional delay measurement needs to be performed for a link, two-way frame delay measurement can be configured to monitor the quality of the link.

Configuring Single-ended SLM in VLAN Networking: This section describes how to configure single-ended synthetic loss measurement (SLM) in virtual local area network (VLAN) networking. To collect performance statistics for frame loss on point-to-multipoint or multipoint-to-multipoint links, deploy single-ended SLM, which helps monitor link quality.

Configuring the ETH-Test Function for a VLAN: The ETH-test function is short for Ethernet test signal. ETH-test instances are performed for a unidirectional on-demand service or during an on-demand-service interruption to calculate parameters, including the maximum bandwidth, frame loss ratio, and bit error rate.

Configuring AIS: Configuring AIS prohibits a MEP in an MD of a higher level from sending the same alarm as that sent by a MEP in an MD of a lower level to the NMS.

Enabling the ETH-BN Receiving Function for a VLAN: When routing devices connect to microwave devices, enable the ETH-BN receiving function to implement association with the microwave bandwidth.
