Introduced on the E-Series. Usage Information The following describes the show interfaces tengigabitethernet 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 AutoNegotiation Remote Partner's Ability AutoNegotiation Expansion 1000Base-T Control 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. 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. 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 requires auto-negotiation. The IEEE Ethernet standard does not support setting a speed to 1000 Mbps with the speed command without autonegotiation. 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.
