Example for Configuring Dual-ended Frame Loss Measurement in VLAN Networking
This section provides an example showing how to configure dual-ended frame loss measurement in VLAN networking.
Networking Requirements
With the increasing popularization and wide application of the Internet, various value-added services such as IPTV, video conferencing, and VoIP services are widely deployed. Link connectivity and network performance determine the Quality of Services (QoS) on bearer networks. Therefore, performance monitoring is especially important for service transmission channels.
As shown in Figure 1, CFM is configured between CEs. To provide high-quality audio services, providers hope to monitor the frame loss over mobile bearer links in real time, while monitoring link connectivity. Monitoring the frame loss over mobile bearer links allows the providers to respond quickly to video service quality deterioration.
Configuration Roadmap
Configure dual-ended frame loss measurement for the end-to-end link between the CEs to collect frame loss statistics.
Data Preparation
To complete the configuration, you need the following data:
Configure the VLAN ID of a interface belong to CE.
Configure the names of the MD and MA between CE1 and CE2.
Configure the interval at which LM messages are sent.
Procedure
- Configure basic Ethernet CFM functions and specify the MEP type as outward.
Configure basic Ethernet CFM functions on each CE. Specify the Ethernet CFM protocol in the version of IEEE Standard 802.1ag-2007. Create an MD named md3 and an MA named ma3, and bind the MA to the VLAN.
