Port Status and Configuration
Viewing Port Status and Configuring Port Parameters
Table 10-1. Status and Parameters for Each Port Type
Status or
Parameter Description
Enabled Yes (default): The port is ready for a network connection.
No: The port will not operate, even if properly connected in a network. Use this setting, for example, if
the port needs to be shut down for diagnostic purposes or while you are making topology changes.
Status
(read-only) Up : The port senses a link beat.
Down : The port is not enabled, has no cables connected, or is experiencing a network error. For
troubleshooting information, refer to the Installation and Getting Started Guide you received with the
switch. Refer also to Appendix C, “Troubleshooting” (in this manual).
Mode The port’s speed and duplex (data transfer operation) setting.
10/100/1000Base-T Ports:
• Auto-MDIX (default): Senses speed and negotiates with the port at the other end of the link for port
operation (MDI-X or MDI).
To see what the switch negotiates for the Auto setting, use the CLI
show interfaces brief command
or the “ 3. Port Status” option under “ 1. Status and Counters” in the menu interface.
• MDI: Sets the port to connect with a PC using a crossover cable (Manual mode—applies only to
copper port switches using twisted-pair copper Ethernet cables)
• MDIX: Sets the port to connect with a PC using a straight-through cable (Manual mode—applies only
to copper port switches using twisted-pair copper Ethernet cables)
• Auto-10: Allows the port to negotiate between half-duplex (HDx) and full-duplex (FDx) while keeping
speed at 10 Mbps. Also negotiates flow control (enabled or disabled). ProCurve recommends Auto­
10 for links between 10/100 auto-sensing ports connected with Cat 3 cabling. (Cat 5 cabling is required
for 100 Mbps links.).
• 10HDx: 10 Mbps, Half-Duplex
• 10FDx: 10 Mbps, Full-Duplex
• Auto-100: Uses 100 Mbps and negotiates with the port at the other end of the link for other port
operation features.
• Auto-10-100 : Allows the port to establish a link with the port at the other end at either 10 Mbps or 100
Mbps, using the highest mutual speed and duplex mode available. Only these speeds are allowed with
this setting.
• Auto-1000: Uses 1000 Mbps and negotiates with the port at the other end of the link for other port
operation features.
• 100Hdx: Uses 100 Mbps, half-duplex.
• 100Fdx: Uses 100 Mbps, Full-Duplex
