Notifications Generated by the Optical Transport Manager lists the notifications generated by the Optical Transport Manager for optical network elements and network connections for SONET/SDH networks.
Managed Element |
Notification |
Condition |
---|---|---|
Card or Equipment |
Down |
A Card or Equipment device in a network element has failed. |
PTP |
Down |
A PTP on a network element has failed. |
PTPHardFailureCondition |
A hard failure indication has been observed on this PTP. |
|
OpticalNetworkElement |
Down |
The EMS has lost management connection with the NE. |
TopologicalLink |
Down |
No traffic is passing through the link in one or both directions and symptoms may indicate fiber failure. |
SignalDegrade |
Traffic is passing through the link but symptoms indicate that the signal is degraded. |
|
DropSideTopologicalLink |
Down |
The drop side topological link is down. |
SignalDegrade |
A signal degrade (soft failure) occurs when the signal error rate reaches a threshold. The impact is a function of the device specification; however, if there is an impact, it will be very similar to Fiber Cut. |
|
Conduit |
Down |
No traffic is passing through the link in one or both directions and symptoms may indicate fiber failure. Physical failure of the link bundle that comprises topological links. |
BBTopologicalLink |
Down |
No traffic is passing through the unmanaged segment in one or both directions. |
SignalDegrade |
Traffic is passing through the link but symptoms indicate that the signal is degraded. |
|
BBDropSideTopologicalLink |
Down |
The edge, unmanaged segment is down. |
SignalDegrade |
A signal degrade (soft failure) occurs when the signal error rate reaches a threshold. The impact is a function of the device specification; however, if there is an impact, it will be very similar to Fiber Cut. |
|
HighOrder_Trail |
TrailDown |
This facility is down. |
TrailAtRisk |
One element of a protection group is down. Communication continues, but without the security of redundancy. |
|
HighOrder_Circuit |
ServiceUnavailable |
This facility is down. May be a result of TransportOutgoingFail, TransportIncomingFail, or TransportFail. |
ServiceAtRisk |
One element of a protection group is down. Communication continues, but without the security of redundancy. |
|
EMS |
Disconnected |
There is a loss of communication with the EMS. |
EmsAdapterNotRunning |
The VMware Smart Assurance EMS adapter has shut down. |
|
EmsAdapterDisconnected |
The VMware Smart Assurance EMS adapter is not responding. |
The following sections describe the root-cause problems and related symptoms for some optical network elements and network connections.
