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.
- Perform the following operations on the MEP and RMEP.
Run system-view
The system view is displayed.
Run cfm md md-name
The MD view is displayed.
Run ma ma-name
The MA view is displayed.
Run map vlan vlan-id
The MA is bound to a VLAN.
Run mep mep-id mep-id interface interface-type interface-number { inward | outward }
An MEP is configured.
Run remote-mep mep-id mep-id
The remote MEP ID is configured.
Run mep ccm-send enable
The CCM transmission function is enabled.
Run remote-mep ccm-receive [ mep-id mep-id ] enable
The CCM reception function is enabled.
(Optional) Run delay-measure one-way threshold threshold-value
The alarm threshold for one-way frame delay measurement is set.
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.
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.

Run remote-mep mep-id mep-id

Run mep ccm-send enable

Run remote-mep ccm-receive [ mep-id mep-id ] enable
The CCM reception function is enabled.
(Optional) Run delay-measure one-way threshold threshold-value
The alarm threshold for one-way frame delay measurement is set.
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.
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.
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.
- Perform the following operations on the MEP and RMEP.
