    2 Some third−party NIC cards can fall back to half−duplex operation mode, even though both the switchport and NIC configuration are manually configured for 100 Mbps, full−duplex. This is because NIC autonegotiation link detection still operates when the NIC is manually configured. This causes duplex inconsistency between the switchport and th ...
