show interfaces phy

Display auto-negotiation and link partner information.

Syntax
show interfaces gigabitethernet slot/port phy
Parameters
tengigabitethernet
Enter the keyword tengigabitethernet then the slot or port information.
NOTE: This command also enables you to view information corresponding to a range of ports. However, for Open Networking (ON) platforms the notation for specifying port range in the command is different from how you specify in non-ON platforms.
  • For non-ON platforms, you can specify multiple ports as slot/port-range. For example, if you want to display information corresponding to all ports between 1 and 4, specify the port range as show interfaces interface-type 1/1 - 4.
  • For ON platforms, you can specify multiple ports as slot/port/[subport] - slot/port/[subport]. For example, if you want to display information corresponding to all ports between 1 and 4, specify the port range as show interfaces interface-type 1/1/1 - 1/1/4.

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
  • 1000MB
  • 100MB
  • 10MB
