Description: The value of the instance of the ifIndex object, defined in MIB-II, for the interface corresponding to this port. In the case of a non-atm port this is the physical ifIndex of that port, in the case of an atm port it is the virtual ifIndex that represents the LEC.

IMPORTANT: By adding a port here, that port will now be part of any VLAN(s) that this port group is associated with. In addition, if the port is a virtual interface that represents a LEC, the ELAN that that LEC represents will also be part of the VLAN that this port group is associated with. Control of the LECs (creating and assignment) is handled by the ATMF Lan Emulation Client MIB, specifically the lecConfigTable in Configuration Group
