Configuring 802.1ag MAC Ping

Context

Similar to IP ping, 802.1ag MAC ping monitors connectivity of a path between a MEP and an RMEP.

802.1ag MAC ping can be only implemented on the network where the MD, MA, and MEP are configured.

Procedure

A device is usually configured with multiple MDs and MAs. To accurately detect connectivity of a link between two or more devices, perform either of the following operations.
- MA view:
  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 ping mac-8021ag mep mep-id mep-id { md md-name ma ma-name { mac mac-address | remote-mep mep-id mep-id } | mac mac-address | remote-mep mep-id mep-id } [ -c count | interface interface-type interface-number | -s packetsize | -t timeout | -p priority-value ] ^*
    
    Connectivity between a MEP and an RMEP or a MIP is monitored.
  - The ping mac-8021ag command without md md-name and ma ma-name specified checks connectivity of links in a specified MA.
  - The ping mac-8021ag command with md md-name and ma ma-name specified checks connectivity of links based on the configured MA and MD.
- All views except the MA view:
  
  Run ping mac-8021ag mep mep-id mep-id md md-name ma ma-name { mac mac-address | remote-mep mep-id mep-id } [ -c count | interface interface-type interface-number | -s packetsize | -t timeout | -p priority-value ] ^*
  
  Connectivity between a MEP and an RMEP or a MIP is monitored.
When performing 802.1ag MAC ping, ensure that:
- The MA has been associated with a VLAN.
- The MEP has been configured in the MA.
- The outbound interface (if specified) cannot be the interface on which an inward-facing MEP is configured. The interface must join the VLAN associated with the MA.
- If the destination node is an RMEP, either mac mac-address or remote-mep mep-id mep-id can be specified. If remote-mep mep-id mep-id is specified, the RMEP must have been created using the remote-mep command and the bridge MAC address of the device on which the RMEP is located must be specified.
- If the destination node is a MIP, specify mac mac-address.
An intermediate device on a link is only used to forward LBMs and LBR messages; therefore, the intermediate device does not need to be configured with the MD, MA, or MEP.
