Table 7 - Configuration Options for Ports 1…8
Configuration Option Description
Transmit & Receive Controls port communication.
Values:
• Both (default)
• Tx
• Rx
• None
Negotiation Indicates whether the port configuration settings are autonegotiated. Select
None to manually configure the port.
Values:
• None
• Auto (default)
Rate Autonegotiates 10 or 100 mbit/s depending on the connected device. The
speed must be manually selected if the negotiation parameter is None.
Values:
• 10
• 100
Duplex Mode Autonegotiates half-duplex or full-duplex mode based on the connected
device. The duplex mode must be manually selected if the negotiation
parameter is changed to None.
Values:
• Half—The switch can either send or receive data, but cannot do both
simultaneously.
• Full—The switch can simultaneously send and receive data.
Flow Control Prevents buffers from over filling.
Values:
• OFF
• ON (default)
TIP
Ports set for autonegotiation default to half-duplex mode if the connected
devices are not configured to autonegotiate.
Turning off autonegotiation disables the auto-MDIX feature. In this case,
crossover cables may be needed to establish communication to the connected
device.
