Version Description
7.6.1.0 Introduced on the C-Series and S-Series.
6.5.4.0 Introduced on the E-Series.
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
