prom Port Group Binding

1.3.6.1.4.1.2167.3.6.1.1.1.10

Each port is associated with a port group. Typically, a port will belong to a port group of one and the value of this object will be the same as the port index for this instance. That is, this port will point to itself. The intent of this object is to help manage ports that have hierarchical relationships. For example, an ATM port typically has a physical port and multiple logical ports (e.g. each logical port corresponding to an instance of an emulated LAN). In this case, each LANE instance would refer to the instance of the physical port associated with the ATM front-end. Another example is an FDDI DAS type port. In this case, there is a logical port associated with the FDDI switch port which is connected to the two FDDI physical port connectors. The physical FDDI ports both point to the logical instance of an FDDI port.
