Display information on all interfaces on a specific stack member.
Syntax

Parameters
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 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.
