Duplicate event
A count of the OAMPDUs received that contain the Event Notification code. This counter is incremented on reception of a
valid frame, with:
• DestinationField equal to the reserved multicast address for slow protocols.
• LengthOrType field value equal to the reserved Type for slow protocols.
• A slow protocols subtype value equal to the subtype reserved for OAM.
• The OAMPDU code equals the Event Notification code.
• The Sequence Number field is equal to the Sequence Number field of the last received Event Notification
OAMPDU.
Generalized nonresettable counter. This counter has a maximum increment rate of slow protocol frames (No more than
10 frames shall be transmitted in any one-second period).
Loopback control
A count of OAMPDUs received that contain the Loopback Control code. This counter is incremented on reception of a
valid frame, with:
• DestinationField equal to the reserved multicast address for slow protocols.
• LengthOrType field value equal to the reserved Type for slow protocols.
• A slow protocols subtype value equal to the subtype reserved for OAM.
• The OAMPDU code equals the Loopback Control code and is supported by the device.
Generalized nonresettable counter. This counter has a maximum increment rate of slow protocol frames (No more than
10 frames shall be transmitted in any one-second period).
Variable request
A count of OAMPDUs received that contain the Variable Request code. This counter is incremented on reception of a
valid frame, with:
• DestinationField equal to the reserved multicast address for slow protocols.
• LengthOrType field value equal to the reserved Type for slow protocols.
• A slow protocols subtype value equal to the subtype reserved for OAM.
• The OAMPDU code equals the Variable Request code and is supported by the device.
Generalized nonresettable counter. This counter has a maximum increment rate of slow protocol frames (No more than
10 frames shall be transmitted in any one-second period).
Variable response
A count of OAMPDUs received that contain the Variable Response code. This counter is incremented on reception of a
valid frame, with:
• DestinationField equal to the reserved multicast address for slow protocols.
• LengthOrType field value equal to the reserved Type for slow protocols.
• A slow protocols subtype value equal to the subtype reserved for OAM.
• The OAMPDU code equals the Variable Response code and is supported by the device.
Generalized nonresettable counter. This counter has a maximum increment rate of slow protocol frames (No more than
10 frames shall be transmitted in any one-second period).
