  2. On the receiver RMEP, perform the following operation:

     Table 1 Enabling the DMM frame reception function

     Scenario	Procedure
     Point-to-point scenario	Performance statistics collection not based on a test instance: Run delay-measure two-way receive mep mep-id The receiver is enabled to receive DMMs. Performance statistics collection based on a specified test instance: Run test-id test-id mep mep-id { remote-mep mep-id } [ 8021p 8021p-value ] [ description description ] A test instance is configured. Run delay-measure two-way receive test-id test-id The receiver is enabled to receive DMMs.
     Point-to-multipoint scenario	Run test-id test-id mep mep-id { remote-mep mep-id } [ 8021p 8021p-value ] [ description description ] A test instance is configured based on RMEPs. Run delay-measure two-way receive test-id test-id The receiver is enabled to receive DMMs.

  3. On the initiator MEP, perform the following operation:

     VLAN-specific two-way frame delay measurement is implemented based on an RMEP ID or destination MAC address:

     • If the local MEP has not learnt the MAC address of the RMEP, specify the RMEP destination MAC address before implementing two-way frame delay measurement.

     • If the local MEP has learnt the MAC address of the RMEP, specify the RMEP ID before implementing two-way frame delay measurement.

• Configure proactive two-way frame delay measurement.

  1. Perform the following operations on the MEP and RMEP.

     1. Run system-view

        The system view is displayed.

     2. Run cfm md md-name

     3. Run ma ma-name

        The MA view is displayed.

     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 }

        An MEP is configured.
