Impact on the System

Possible Causes

The MEP received no CCM in a period of time 3.5 times the interval at which CCMs were sent.

Procedure

Perform the following operations to check the network operating status on the MEP:
1. Run the display cfm mep [ md md-name [ ma ma-name [ mep-id mep-id ] ] ] command to view the value of the Interface Name field. Obtain the interface type and number.
2. Run the display interface interface-type interface-num command with the obtained interface type and number specified. View the value of the current state field.
  - If the value of the current state field is Up, go to Step 2.
  - If the value of the current state field is not Up, the interface connection fails. For the troubleshooting procedure, see "Physical Interconnection Troubleshooting."
Run the display cfm mep [ md md-name [ ma ma-name [ mep-id mep-id ] ] ] command to view the value of the CCM Send field on the RMEP. Check whether the RMEP is enabled to send CCMs.
- If the value of the CCM Send field is enabled, go to Step 4.
- If the value of the CCM Send field is disabled, go to Step 3.
Perform the following steps on the RMEP:
1. Run the cfm md md-name command to enter the MD view.
2. Run the ma ma-name command to enter the MA view.
3. Run the mep ccm-send enable command to enable the RMEP to send CCMs. Check whether the trap is cleared. If the trap persists, go to Step 4.
Run the display cfm remote-mep [ md md-name ma ma-name mep-id mep-id ] command to view the value of the CCM Receive field on the MEP.
- If the value of the CCM Receive field is enabled, go to Step 6.
- If the value of the CCM Receive field is disabled, go to Step 5.
Perform the following steps on the MEP:
1. Run the cfm md md-name command to enter the MD view.
2. Run the ma ma-name command to enter the MA view.
3. Run the remote-mep ccm-receive enable command to enable the MEP to receive CCMs. Check whether the trap is cleared. If the trap persists, go to Step 6.
Collect alarm information and configuration information, and then contact technical support personnel.
