Configuring Dual-ended Frame Loss Measurement in VLAN Networking

Context

Dual-ended frame loss measurement in VLAN networking is carried out continuously to permit proactive reporting of frame loss or performance results.

Dual-ended frame loss measurement in VLAN networking is usually deployed on end-to-end MEPs. Frame loss statistics are collected based on the transmit and receive counters carried by CCMs. Dual-ended frame loss measurement can be successfully performed only when the RMEP is in the Up state.

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

Perform the following steps on the devices initiates dual-ended frame loss measurement:
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
  
  The RMEP ID is configured.
7. Run mep ccm-send [ mep-id mep-id ] enable
  
  The MEP is enabled to send CCMs.
8. Run remote-mep ccm-receive [ mep-id mep-id ] enable
  
  The MEP is enabled to receive CCMs from the RMEP.
9. Run loss-measure dual-ended continual mep mep-id remote-mep mep-id
  
  Dual-ended frame loss measurement is enabled in the VLAN.
