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-100: Uses 100 Mbps and negotiates with the port at the other end of the link for other port
operation features.
• 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
Notes:
• Changing the port speed on a transceiver port requires a reboot of the switch.
• 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 connects must also be configured to "Auto" and
operate in compliance with the IEEE 802.3ab "Auto Negotiation" standard for 1000Base-T networks.
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). 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
• Auto-100: Uses 100 Mbps and negotiates with the port at the other end of the link for other port
operation features.
• 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
