You can set up the unit to propagate a fault detected on one port to another port.
Fault propagation can be used to propagate one of the following:
- Link status only
- EVC status (link status is included)
If you are using link status, only a link that is down on one port can bring the other port down.
If you are using EVC status, the status of PAA probe(s) and/or CFM MEP(s) are propagated to the other port. For more information on PAA and CFM MEP, refer to the chapter .
At least one PAA probe or CFM MEP should be free of connectivity errors in order to enable fault propagation on EVC status to the specified port. If there is no PAA probe and no CFM MEP set up in EVC fault propagation mode for the specified port, the port selected for fault propagation will remain down.
To set up port fault propagation
Access the page Port ▶Configuration.
Click the Port Name to edit its settings.
Define port parameters as required by your setup, then click Apply.
