Usage Information The following describes the show interfaces gigabitethernet command following example.
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 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.
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
Link Status: Up or Down
Speed:
• Auto
