Configuring Single-ended SLM in a VLAN

Context

To collect packet loss statistics on a point-to-multipoint or multipoint-to-multipoint link, you can deploy single-ended SLM to monitor the link quality.

Single-ended SLM in a VLAN falls into on-demand and proactive single-ended SLM. On-demand single-ended SLM, which is triggered manually, collects single-ended frame loss statistics for diagnosis at one time or periodically. Proactive single-ended SLM is carried out continuously.

To collect single-ended SLM statistics at one time or periodically, configure on-demand single-ended SLM.
To collect single-ended SLM statistics continuously, configure proactive single-ended SLM.

Procedure

Configure on-demand single-ended SLM.
1. Perform the following operations on both devices of the link enabled with single-ended SLM.
  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 [ pe-vid pe-vid ce-vid ce-vid ] { inward | outward }
    
    A MEP is configured.
  6. Run remote-mep mep-id mep-id [ mac mac-address ]
    
    The remote MEP ID is configured.
  7. Run mep ccm-send [ mep-idmep-id ] enable
    
    The MEP is enabled to send CCMs.
  8. Run remote-mep ccm-receive [ mep-idmep-id ] enable
    
    The RMEP is enabled to receive CCMs.
  9. Run test-id test-id mep mep-id { remote-mep mep-id } [ 8021p 8021p-value ] [ description description ]
    
    A test instance is configured.
2. Perform the following operation on the receive device of the link enabled with single-ended SLM.
  
  Run loss-measure single-ended-synthetic receive test-id test-id [ time-out timeout-value ]
  
  The device is configured to receive SLM frames.
3. Perform the following operation on the transmit device of the link enabled with single-ended SLM.
  
  Run loss-measure single-ended-synthetic send test-id test-id interval { 3.3 | 10 | 100 | 1000 | 10000 } [ sending-count count-value ] [ time-out time-out-value ] [ packet-size packet-size ] [ measurement-count measurement-count ]
  
  On-demand single-ended SLM is configured.
Configure proactive single-ended SLM.
1. Perform the following operations on both devices of the link enabled with single-ended SLM.
  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 [ pe-vid pe-vid ce-vid ce-vid ] { inward | outward }
    
    A MEP is configured.
  6. Run remote-mep mep-id mep-id [ mac mac-address ]
    
    The remote MEP ID is configured.
  7. Run mep ccm-send [ mep-idmep-id ] enable
    
    The MEP is enabled to send CCMs.
  8. Run remote-mep ccm-receive [ mep-idmep-id ] enable
    
    The RMEP is enabled to receive CCMs.
  9. Run test-id test-id mep mep-id { remote-mep mep-id } [ 8021p 8021p-value ] [ description description ]
    
    A test instance is configured.
2. Perform the following operation on the receive device of the link enabled with proactive single-ended SLM.
  
  Run loss-measure single-ended-synthetic receive test-id test-id [ time-out timeout-value ]
  
  The remote device is configured to receive SLM frames.
3. Perform the following operations on the initiator of the link enabled with proactive single-ended SLM.
  
  Run loss-measure single-ended-synthetic continual sendtest-idtest-idinterval { 3.3 | 10 | 100 | 1000 | 10000 } [ sending-countcount-value ] [ time-outtimeout ] [ packet-sizepacket-size ]
  
  Proactive single-ended SLM is configured.
4. (Optional) Configure the remote packet loss ratio thresholds for single-ended SLM on both devices.
  - Run loss-measure single-ended-synthetic remote-ratio-threshold test-id upper-limit upper-limit lower-limit lower-limit
    
    Remote packet loss rate thresholds are configured for single-ended SLM.
  - Run loss-measure single-ended-synthetic local-ratio-threshold test-id upper-limit upper-limit lower-limit lower-limit
    
    Local packet loss rate thresholds are configured for single-ended SLM.
