32 CHAPTER 4: CONFIGURING THE SWITCH ■ Label - Optional name for the port to help you identify the device connected to it. For example, if an access point is connected to this port, you can label it as Access Point. ■ Status - Enables and disables the port ■ Flow Control - Enables and disables flow control on the port. When flow control is enabled for the port, the Switch regulates the packet flow so that a sending device does not transmit more packets than a receiving device can process. If flow control is disabled, packets may be dropped under certain periods of high traffic. Flow control is enabled by default. ■ Speed Duplex - Sets the speed and duplex mode of the port. Available options include auto, 10 half-duplex, 10 full-duplex, 100-half duplex, and 100 full-duplex. For 1000 Mbps connections, see See "Speed/Duplex for 1000 Mbps Connections" on page 32. Auto (or autonegotiation), which is enabled by default, sets the optimum combination of speed and duplex that can be supported by both ends of the link. ■ Priority - Set the priority for the traffic that passes through this port. Available options include Standard (default), High, Intermediate, and Low. If you modify any of these basic port settings, click Apply to save your changes. Figure 12 Basic Port Configuration Page Speed/Duplex for 1000 Mbps Connections You cannot preset the speed to 1000Mbps. To run a port at 1000Mbps, you must enable autonegotiation for the port. When autonegotiation is enabled, the Switch will automatically connect at 1000Mbps, providing the connected device also supports this speed. 1000Mbps connections are always full-duplex. Half-duplex connections are only available for 10Mbps and 100Mbps settings. CAUTION: Before manually setting a port to full-duplex, verify that the device connected to the port is also manually set to the same speed and duplex setting. If connecting link partners are left to autonegotiate for a link manually set on this switch to full-duplex, they will

Speed/Duplex for 1000 Mbps Connections
You cannot preset the speed to 1000Mbps. To run a
port at 1000Mbps, you must enable autonegotiation for
the port. When autonegotiation is enabled, the Switch
will automatically connect at 1000Mbps, providing the
connected device also supports this speed.
1000Mbps connections are always full-duplex.
Half-duplex connections are only available for 10Mbps
and 100Mbps settings.
CAUTION:
Before manually setting a port to full-duplex,
verify that the device connected to the port is also
manually set to the same speed and duplex setting. If
connecting link partners are left to autonegotiate for a
link manually set on this switch to full-duplex, they will
