Configuring Interface Connections
You can use the Trunk Configuration or Port Configuration page to enable/dis-
able an interface, manually fix the speed and duplex mode, set flow control, set
auto-negotiation, and set the interface capabilities to advertise.
Command Attributes
> Name – Allows you to label an interface. (Range: 1-64 characters)
> Admin – Allows you to manually disable an interface. You can disable an inter-
face 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 reasons.
> 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 IEEE 802.3x
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
>> Sym
- Transmits and receives pause frames for flow control
>> FC
- Supports flow control
