ethIfOperStatus 1.3.6.1.4.1.2928.2.2.1.3.2.1.8

The actual operational state of the interface. The value should normally follow the administrative state (ethIfAdminStatus). up(1). The interface is up and operational. If the interface is representing a unicast ETS TTP, then both the originating and terminating connections have been established. For a multicast type, the originating connection has been established to all the configured destinations. Note that a multicast ETS TTP does not require terminating connections to be operational. If the interface is representing an interface group, then the operational status of all member interfaces are set to `up(1)'. down(2). The interface is not operational. dormant(5). This value is only applicable for Ethernet Transport Service Trail Termination Points (ETS TTP). The TTP is pending establishment of the terminating connection from the remote node. notPresent(6). The physical interface (and its device) is not present. partial(9). If the interface is representing a multicast ETS TTP, then the connections have been established to some, but not to all the configured destinations. If the interface is representing an interface group, then some but not all member interfaces have their operational status set to `up(1).
