Description: An entry containing information about a single VSI logical interface. Entries are instantiated and removed as signalled by the slave which controls the external interface. Each entry contains information about the capacity of cross-connects the interface can bear, cell rate, merge capability, vpi/vci ranges, and statistics. Pairs of logical interfaces support potential cross-connects that, when actualized, are represented by the vsiXCEntrys in the vsiXCTable. Logical interfaces are controlled by a designated slave, as determined by the switch. The slave is in the domain of the controller whose identity is given by vsiLogicalIfControllerIndex. This object is an opaque identifier, provided by the slave, and used as a key to identify the entry.
