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 linkbeat.
(read-only)
Down: The port is not enabled, has no cables connected, or is experiencing a network error. For
troubleshooting information, see the installation manual you received with the switch. See also chapter 11,
“Troubleshooting” (in this manual).
Mode The port’s speed and duplex (data transfer operation) setting.
10/100Base-T ports:
• Auto (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. If “Auto” is used, the device to which the port connects 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 command or the “
3. Port Status” option under “1. Status and Counters” in the menu interface.
• 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 autosensing ports connected with Cat 3 cabling. (Cat 5 cabling is required for 100 Mbps
links.).
