Figure 4-12: Port Configuration
Admin field. Allows you to Enable or Disable the port.
State field. The State field displays the Spanning Tree State of the port (Blocking, Listening,
Learning, Forwarding, or Disabled). You can only observe the status of the ports; you cannot
modify this field. The Spanning Tree Protocol controls this field.
Rate/Duplex field. Offers the choice of Full-duplex, Half-duplex, or Auto negotiation.
Enabling auto-negotiation on a port allows a port to sense the communication speed and negotiate
the duplex mode (full duplex or half duplex) automatically. The ports will select the highest
possible throughput. The port can auto-negotiate with any port that is compliant with IEEE
802.3u. If the other port is not IEEE802.3u compliant, the port will default to half-duplex, 10
Mbps mode. Users can operate the communication speed and duplex mode manually.
Flow Control. Allows you to enable or disable Flow Control.
Flow control is a protocol that prevents packets from being dropped by reducing the amount of
traffic to a level that can be accommodated. If enabled on both ends of a connection, it will
prevent the sender from sending data until the receiver can accept it. This switch complies with
the IEEE802.3x flow control standard.
Comments. Allows you to name the port or make notes.
