Port Settings

Use the Port Settings window to make sure that the basic port settings are compatible with the devices to be connected. These settings determine how data is received and sent between the switch and the attached device. You can change these settings to fit your network needs and to troubleshoot network problems.

Basic Port Settings

Port	The number of the switch port, including port type (such as Fa for Fast Ethernet and Gi for Gigabit Ethernet), the module slot number (0, 1, or 2), and the specific port number. The Ethernet Management port is Fa0.
Description	The description of the switch port. The limit is 18 characters. We recommend providing a port description to help identify the port during monitoring and troubleshooting. The description can be the location of the connected device or the name of the person using the connected device.
Enable	The state of the switch port. Check Enabled to enable the port. Deselect the check box of a port to administratively (manually) shut down the port. We recommend disabling the port if the port is not in use and is not attached to a device. An example of when to change this setting is during troubleshooting. You can troubleshoot a suspected unauthorized connection by administratively disabling the port.
Speed	The operating speed of the switch port. Select the speed from the drop-down list. You can select Auto (autonegotiation) if the connected device can negotiate the link speed with the switch port. The default is Auto. An example of when to change this setting is during troubleshooting. If you are troubleshooting a connectivity problem, you can change this setting to see if the switch port and connected device have a speed mismatch. Note: Note: You cannot configure the speed setting on the 10-Gigabit module ports.
Duplex	The duplex mode of the switch port. The default is Auto. Choose the duplex mode from the drop-down list: Auto (autonegotiation) if the connected device can negotiate with the switch Full (full duplex) if both devices can send data at the same time Half (half duplex) if one or both devices cannot send data at the same time Note: On Gigabit Ethernet ports only, you cannot set the port to half duplex if the port speed is set to Auto. An example of when to change this setting is during troubleshooting. If you are troubleshooting a connectivity problem, you can change this setting to verify if the switch port and connected device have a duplex mismatch.

An example of when to change this setting is during troubleshooting. If you are troubleshooting a connectivity problem, you can change this setting to verify if the switch port and connected device have a duplex mismatch.
PoE	Whether Power over Ethernet (PoE) will be supplied to a connected device. Select auto or never from the drop-down list. Note: This setting is available on PoE ports.
