Configuring One-way Frame Delay Measurement

Context

To measure the one-way frame delay at a time or a specific number of times, use the on-demand mode.
To measure the one-way frame delay periodically, use the proactive mode.

Procedure

Configure on-demand one-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
    
    The MD view is displayed.
  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 { inward | outward }
    
    An MEP is configured.
  6. Run remote-mep mep-id mep-id
    
    The remote MEP ID is configured.
  7. Run mep ccm-send enable
    
    The CCM transmission function is enabled.
  8. Run remote-mep ccm-receive [ mep-id mep-id ] enable
    
    The CCM reception function is enabled.
  9. (Optional) Run delay-measure one-way threshold threshold-value
    
    The alarm threshold for one-way frame delay measurement is set.
2. On the receiver RMEP, run delay-measure one-way receive mep mep-id
  
  The RMEP is enabled to receive DM messages.
  
  By default, the RMEP is not enabled to receive DM frames.
3. On the initiator MEP, run delay-measure one-way send mep mep-id { mac mac-address | remote-mep mep-id } interval { 1000 | 10000 } count count-value
  
  On-demand one-way frame delay measurement is configured.
  
  By default, on-demand one-way frame delay measurement is not configured in an MA.
  VLAN-specific one-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 one-way frame delay measurement.
  - If the local MEP has learnt the MAC address of the RMEP, specify the RMEP ID before implementing one-way frame delay measurement.
Configure one-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
    
    The MD view is displayed.
  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
    
    An MEP is configured.
  6. Run remote-mep mep-id mep-id
    
    The remote MEP ID is configured.
  7. Run mep ccm-send enable
    
    The CCM transmission function is enabled.
  8. Run remote-mep ccm-receive [ mep-id mep-id ] enable
    
    The CCM reception function is enabled.
  9. (Optional) Run delay-measure one-way threshold threshold-value
    
    The alarm threshold for one-way frame delay measurement is set.
2. On the receiver RMEP, run delay-measure one-way continual receive mep mep-id
  
  The RMEP is enabled to receive DM messages.
  
  By default, the RMEP enabled with proactive one-way frame delay measurement in an MA is not configured to receive DM frames.
3. On the initiator MEP, run delay-measure one-way continual send mep mep-id { mac mac-address | remote-mep mep-id } interval 1000
  
  Proactive one-way frame delay measurement is configured.
  
  By default, proactive one-way frame delay measurement is not configured in an MA.
