Controlling the analysis of wide area networks
In a wide area network (WAN), where multiple logical connections emanate from a single
physical interface, the
IP Manager
performs WAN analysis by default and diagnoses one of the following problems listed in Problems diagnosed by IP Manager in a WAN.Problem | Description |
|---|---|
Interface::Down | If the physical interface is operationally down, which explains why all of the subinterfaces that are layered over the physical interface have failed, along with any
peer interfaces of those subinterfaces. “Interface” in “Interface::Down” represents the physical interface. |
Interface::LogicalConnectionDown |
|
NetworkConnection::Down | If a single network connection at the subinterface level has failed. |
Whether or not the
IP Manager
performs WAN analysis is controlled by the SM_LOGICALCONNECTIONDOWN environment variable.
