To view a summary of the statistics of each OAM instance

  1. Access the page OAM â–¶Statistics.

  2. For detailed OAM statistics, click the OAM instance Name in the list.

For more information on specific parameters, refer to the following tables.

OAM Statistics (OAM â–¶Statistics)

Parameter Description
Name The name given to the OAM instance.
Rcv OAMPDU The number of OAMPDUs received by this instance, all types combined: info, var request, var response, loopback etc.
Txm OAMPDU The number of OAMPDUs transmitted by this instance, all types combined: info, var request, var response, loopback etc.
Rcv Info OAMPDUs The number of Info OAMPDUs received by this instance.
Txm Info OAMPDUs The number of Info OAMPDUs transmitted by this instance.

Receive

Parameter Description
Unsupported Codes A count of OAMPDUs received that contain an OAM code that is not supported by the device. This counter is incremented upon reception of a valid frame with the following:
  • Destination field value equal to the reserved multicast address for slow protocols.
  • Length Or Type field value equal to the reserved Type for slow protocols.
  • A slow protocols subtype equal to the subtype reserved for OAM.
  • An OAMPDU code for a function that is not supported by the device.
Generalized and non-resettable, this counter has a maximum increment rate for slow protocol frames: no more than 10 frames are transmitted in any one-second period.
Information A count of OAMPDUs received that contain the OAM Information code. This counter is incremented upon reception of a valid frame with the following:
  • Destination field value equal to the reserved multicast address for slow protocols.
  • Length Or Type field value equal to the reserved Type for slow protocols.
  • A slow protocols subtype equal to the subtype reserved for OAM.
  • An OAMPDU code for a function that is not supported by the device.
Generalized and non-resettable, this counter has a maximum increment rate for slow protocol frames: no more than 10 frames are transmitted in any one-second period.
Loopback Control A count of OAMPDUs received that contain the Loopback Control code. This counter is incremented upon reception of a valid frame with the following:
  • Length Or Type field value equal to the reserved Type for slow protocols.
  • A slow protocols subtype equal to the subtype reserved for OAM.
  • An OAMPDU code for a function that is not supported by the device.

    • Generalized and non-resettable, this counter has a maximum increment rate for slow protocol frames: no more than 10 frames are transmitted in any one-second period.
    Variable Request A count of OAMPDUs received that contain the Variable Request code. This counter is incremented upon reception of a valid frame with the following:
  • Length Or Type field value equal to the reserved Type for slow protocols.
  • A slow protocols subtype equal to the subtype reserved for OAM.
  • An OAMPDU code for a function that is not supported by the device.

    • Generalized and non-resettable, this counter has a maximum increment rate for slow protocol frames: no more than 10 frames are transmitted in any one-second period.
    Variable Response A count of OAMPDUs received that contain the Variable Response code. This counter is incremented upon reception of a valid frame with the following:
  • Length Or Type field value equal to the reserved Type for slow protocols.
  • A slow protocols subtype equal to the subtype reserved for OAM.
  • An OAMPDU code for a function that is not supported by the device.

    • Generalized and non-resettable, this counter has a maximum increment rate for slow protocol frames: no more than 10 frames are transmitted in any one-second period.
    Organization Specific A count of OAMPDUs received that contain the Organization Specific code. This counter is incremented upon reception of a valid frame, with:
  • Length Or Type field value equal to the reserved Type for slow protocols.
  • A slow protocols subtype equal to the subtype reserved for OAM.
  • An OAMPDU code for a function that is not supported by the device.

    • Generalized and non-resettable, this counter has a maximum increment rate for slow protocol frames: no more than 10 frames are transmitted in any one-second period.
