Configuring Single-ended Frame Loss Measurement in VLAN Networking

Context

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.

Single-ended frame loss measurement in VLAN networking can be either on-demand or proactive. On-demand single-ended frame loss measurement is manually initiated for diagnosis of frame loss in a limited time. It can be singular or periodic measurement. Proactive single-ended frame loss measurement is performed continuously to permit proactive reporting of frame loss or performance results.

  • To implement singular or periodic single-ended frame loss measurement, configure on-demand single-end frame loss measurement in VLAN networking.

  • To implement continual single-ended frame loss measurement, configure proactive single-ended frame loss measurement in VLAN networking.

Only S5730-HI, S5731-H, S5731-S, S5731S-H, S5731S-S, S5732-H, S6720-HI, S6730-H, S6730S-H, S6730-S, and S6730S-S support this function.

Procedure

  • Configure on-demand single-ended frame loss measurement.

    1. Perform the following steps on the devices configured with MEPs at both ends of a link:
      1. Run system-view

      4. Run map vlan vlan-id

        The MA is bound to a VLAN.

      5. Run mep mep-id mep-id interface interface-type interface-number [ pe-vid pe-vid ce-vid ce-vid ] { inward | outward }

        A MEP is configured.

      1. Run the test-id test-id mep mep-id { remote-mep mep-id } [ 8021p 8021p-value ] [ description description ] command to configure a test instance for a specific RMEP.
      2. Run the loss-measure single-ended receive test-id test-id command to enable the RMEP to receive LMMs.

    3. Perform configurations for enabling a MEP to send LMMs.

      P2P scenario

      Non-test instance-based statistics

      Run the loss-measure single-ended send mep mep-id [ mac mac-address | remote-mep mep-id ] interval { 1000 | 10000 } count count-value command to enable single-ended frame loss measurement in a VLAN.

      P2MP scenario

      Test instance-based statistics

      1. Run the test-id test-id mep mep-id { remote-mep mep-id } [ 8021p 8021p-value ] [ description description ] command to configure a test instance for a specific RMEP.
      2. Run the loss-measure single-ended send test-id test-id interval { 1000 | 10000 } count count-value command to enable on-demand single-ended frame loss measurement.

      Single-ended frame loss measurement is implemented for the link between the local MEP and an RMEP identified by an ID or a MAC address.

      • If the local MEP has not learned the MAC address of the RMEP, the MAC address of the RMEP must be specified to implement single-ended frame loss measurement.

      • If the local MEP has learned the MAC address of the RMEP, the ID of the RMEP can be used to implement single-ended frame loss measurement.

  • Configure proactive single-ended frame loss measurement.

    1. Perform the following steps on the devices at both ends of a link where proactive single-ended frame loss measurement will be implemented:
      1. Run system-view

        The system view is displayed.

      2. Run cfm md md-name

        The MD view is displayed.

      3. Run ma ma-name
