Card Slot and Logical Interface Numbering

Port adapter and cable interface line card slots maintain the same slot number regardless of whether other port adapters or cable interface line cards are installed or removed. However, when you move a port adapter or a line card to a different slot, the logical interface number changes to reflect the new slot number.
