76 Configuring & Monitoring the Switch VH-2402S
Configuring Port Operation
You can configure switch ports for operational parameters such as auto-
negotiation, duplex mode, port speed and flow control. The 100Base-FX
fiber ports always operate in full duplex mode and 100Mbps speed.
Therefore, these two parameters, along with auto-negotiation, are not
configurable on these fiber ports.
To configure port operation, do the following:
1. Select Device Control Menu from the Main Menu.
2. Select Port Configuration and press [Enter].
3. Select the stack unit and port number to configure.
4. In the Admin column, select ENABLED. You can also disable the port
due to abnormal behavior or for security reasons.
5. In the Flow Control column, select ENABLED to enable flow control
or DISABLED to disable it. When enabled, the switch uses back
pressure for half duplex and IEEE 802.3x for full duplex. These flow
control methods can also be set directly by selecting
BACK_PRESSURE or 802.3X. Note that flow control should not be
used of the port is connected to a hub.
6. In the Speed and Duplex column, select AUTO to enable Auto-
negotiation for the port, or select 1000_FULL, 1000_HALF,
100_FULL, 100_HALF, 10_FULL, or 10_HALF.
If Auto-negotiation is not enabled, the duplex mode and port
speed needs to be configured.
