Configuring the Switch

Port Settings

Auto-Negotiation Note: This feature complies with the IEEE 802.3u Auto Negotiation standard, and is the default setting for the 10/100TX ports on the switch. Using Auto, the port automatically selects the network speed (10 or 100 Mbps) and the data transfer operation (full- or half-duplex) for the connection to another device, provided that the other device also complies with the IEEE 802.3u Auto Negotiation protocol and is set to Auto. 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.

Flow Control Note:

■IEEE 802.3 Flow Control is applied to ports that are configured to operate in full-duplex mode only. When the switch detects congestion on a port, it transmits a special “pause” (XOFF) packet out the port. The receiving device must support 802.3x flow control in order to interpret this packet. The receiving device will halt transmission of any packets until the switch sends a “resume” (XON) packet.

■Back pressure is applied to ports that are configured to operate in half- duplex mode. When the switch detects congestion on the port, it issues a JAM signal, simulating a collision that prevents other attached stations from transmitting. It is recommended that if you use this flow control method, it should be configured only on those ports that are connected to a single end node, not on ports that are connected to a switch, hub, bridge, or router.
