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 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.
