AutoNegotiation Expansion ParallelDetectionFault is the handshaking scheme in which the link partner
continuously transmit an “idle” data packet using the Fast Ethernet MLT-3
waveform. Equipment that does not support auto-negotiation must be
configured to exactly match the mode of operation as the link partner or else
no link can be established.
1000Base-T Control 1000Base-T requires auto-negotiation. The IEEE Ethernet standard does not
support setting a speed to 1000 Mbps with the speed command without
auto-negotiation. E-Series line cards support both full-duplex and half-duplex
1000BaseT.
