Why some interfaces are unmanaged
An interface may be shown in OpManager as unmanaged due to the following reasons:
- The user has manually chosen to unmanage the interface
- The interface is discovered / listed as a sub-interface.
A subinterface is a virtual interface created by dividing one physical interface into multiple logical interfaces. A sub-interface in a Router uses the parent physical interface for sending and receiving data.OpManager does not manage those interfaces which are listed as sub-interfaces.
Hence, If the interface is discovered/listed as an sub-interface, it will be shown as unmanaged.
