Mode Status Displays auto negotiation fault information. When the interface completes auto
negotiation successfully, the autoNegComplete eld and the linkstatus eld read
“True.”
AutoNegotiation
Advertise
Displays the control words the local interface advertises during negotiation. Duplex is
either half or full. Asym- and Sym Pause is the types of ow 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 ow 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 congured 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.
