In brief, for switches, line-rate or wire-speed basically means the device has the forwarding (PPS) capacity to support all ports, concurrently, at 100% capacity (even at minimum packet sizes). Non-blocking often means the switch's internal bandwidth has sufficient capacity to carry all the port bandwidths, concurrently, at full capacity. Non-blocking could also mean the switch's architecture isn't prone to head-of-line blocking.
