Displays the control words the local interface advertises during negotiation. Duplex
is either half or full. Asym- and Sym Pause is the types of flow control the local
interface supports.
AutoNegotiation
Remote Partner’s
Ability
Displays the control words the remote interface advertises during negotiation.
Duplex is either half or full. Asym- and Sym Pause is the types of flow control
the remote interface supports.
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.
