Line Description
Mode Control Indicates if auto negotiation is enabled. If so, indicates the selected
speed and duplex.
Mode Status Displays auto negotiation fault information. When the interface
completes auto negotiation successfully, the autoNegComplete field
and the linkstatus field read “True.”
AutoNegotiation Advertise Displays the control words advertised by the local interface during
negotiation. Duplex is either half or full. Asym- and Sym Pause is the
types of flow control supported by the local interface.
AutoNegotiation Remote
Partner’s Ability
Displays the control words advertised by the remote interface during
negotiation. Duplex is either half or full. Asym- and Sym Pause is the
types of flow control supported by the remote interface
AutoNegotiation

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.
Phy Specific Control Values are:
0 - Manual MDI
1 - Manual MDIX
2 - N/A
3 - Auto MDI/MDIX
Phy Specific Status Displays PHY-specific status information. Cable length represents a
rough estimate in meters:
0 - < 50 meters
1 - 50 - 80 meters
2 - 80 - 110 meters
3 - 110 - 140 meters
4 - 140 meters.
