This is the implementation of Netlink notifications out of CFM.
Notifications are initiated whenever a state change happens in CFM.
IFLA_BRIDGE_CFM:
Points to the CFM information.
IFLA_BRIDGE_CFM_MEP_STATUS_INFO:
This indicate that the MEP instance status are following.
IFLA_BRIDGE_CFM_CC_PEER_STATUS_INFO:
This indicate that the peer MEP status are following.
CFM nested attribute has the following attributes in next level.
IFLA_BRIDGE_CFM_MEP_STATUS_INSTANCE:
The MEP instance number of the delivered status.
The type is NLA_U32.
IFLA_BRIDGE_CFM_MEP_STATUS_OPCODE_UNEXP_SEEN:
The MEP instance received CFM PDU with unexpected Opcode.
The type is NLA_U32 (bool).
IFLA_BRIDGE_CFM_MEP_STATUS_VERSION_UNEXP_SEEN:
The MEP instance received CFM PDU with unexpected version.
The type is NLA_U32 (bool).
IFLA_BRIDGE_CFM_MEP_STATUS_RX_LEVEL_LOW_SEEN:
The MEP instance received CCM PDU with MD level lower than
configured level. This frame is discarded.
The type is NLA_U32 (bool).
IFLA_BRIDGE_CFM_CC_PEER_STATUS_INSTANCE:
The MEP instance number of the delivered status.
The type is NLA_U32.
IFLA_BRIDGE_CFM_CC_PEER_STATUS_PEER_MEPID:
The added Peer MEP ID of the delivered status.
The type is NLA_U32.
IFLA_BRIDGE_CFM_CC_PEER_STATUS_CCM_DEFECT:
The CCM defect status.
The type is NLA_U32 (bool).
True means no CCM frame is received for 3.25 intervals.
IFLA_BRIDGE_CFM_CC_CONFIG_EXP_INTERVAL.
IFLA_BRIDGE_CFM_CC_PEER_STATUS_RDI:
The last received CCM PDU RDI.
The type is NLA_U32 (bool).
IFLA_BRIDGE_CFM_CC_PEER_STATUS_PORT_TLV_VALUE:
The last received CCM PDU Port Status TLV value field.
The type is NLA_U8.
IFLA_BRIDGE_CFM_CC_PEER_STATUS_IF_TLV_VALUE:
The last received CCM PDU Interface Status TLV value field.
The type is NLA_U8.
IFLA_BRIDGE_CFM_CC_PEER_STATUS_SEEN:
A CCM frame has been received from Peer MEP.
The type is NLA_U32 (bool).
This is cleared after GETLINK IFLA_BRIDGE_CFM_CC_PEER_STATUS_INFO.
IFLA_BRIDGE_CFM_CC_PEER_STATUS_TLV_SEEN:
A CCM frame with TLV has been received from Peer MEP.
The type is NLA_U32 (bool).
This is cleared after GETLINK IFLA_BRIDGE_CFM_CC_PEER_STATUS_INFO.
IFLA_BRIDGE_CFM_CC_PEER_STATUS_SEQ_UNEXP_SEEN:
A CCM frame with unexpected sequence number has been received
from Peer MEP.
The type is NLA_U32 (bool).
When a sequence number is not one higher than previously received
then it is unexpected.
This is cleared after GETLINK IFLA_BRIDGE_CFM_CC_PEER_STATUS_INFO.
