Port Status and Basic 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 Up: The port senses a link beat.

(read-only)

Down: The port is not enabled, has no cables connected, or is experiencing a network error. For

troubleshooting information, refer to the installation manual 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.

10/100Base-T ports:

• auto-mdix (default): Senses speed and negotiates with the port at the other end of the link for data

transfer operation (half-duplex or full-duplex).

Note: Ensure that the device attached to the port is configured for the same setting that you select

here. Also, if “Auto” is used, the device to which the port is connected must operate in compliance

with the IEEE 802.3u “Auto Negotiation” standard for 100Base-T networks. If the other device does

not comply with the 802.3u standard, or is not set to Auto, then the port configuration on the switch

must be manually set to match the port configuration on the other device.

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). HP 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

• 100HDx: 100 Mbps, Half-Duplex

• 100FDx: 100 Mbps, Full-Duplex

100FX ports:

• 100HDx: 100 Mbps, Half-Duplex

• 100FDx (default): 100 Mbps, Full-Duplex
