2-28Configuring Interface Connections
Use the Port Configuration and Trunk Configuration pages to
enable/disable an interface, manually set the speed and duplex mode, set
flow control, and set auto-negotiation parameters.
Fields and Attributes
•Name – Allows you to label an interface. (Range: 1-64 characters)
•Admin – Allows you to manually disable an interface. You can disable
an interface due to abnormal behavior (e.g., excessive collisions), and
then reenable it after the problem has been resolved. You may also
disable an interface for security rea sons.
•Speed/Duplex – Allows manual selection of port speed and duplex
mode (i.e., with auto-negotiation disabled.)
•Flow Control – Allows automatic or manual selection of flow control.
• Flow control can eliminate frame loss by “blocking” traffic from
end stations or segments connected directly to the switch when its
buffers fill. When enabled, back pressure is used for half-duplex
operation and IEEE802.3x for full-duplex operation.
• Flow control should not be used if a port is connected to a hub.
Otherwise flow control signals will be propagated throughout the
segment.
•Autonegotiation/Port Capabilities – Allows auto-negotiation to be
enabled/disabled. Specifies the capabilities to be advertised for a port
during auto-negotiation. The following capabilities are supported:
•10half - Supports 10 Mbps half-duplex operation
•10full - Supports 10 Mbps full-duplex operation
•100half - Supports 100 Mbps half-duplex operation
•100full - Supports 100 Mbps full-duplex operation
•1000full - Supports 1000 Mbps full-duplex operation
