Port Configurations

This section contains information for configuring various attributes and properties for individual physical ports, including port
speed and flow control. Clicking on Port Configurations in the Configuration menu will display the following window for the
user:
To configure switch ports:
1. Choose the port or sequential range of ports using the From...To... port pull-down menus.
2. Use the remaining pull-down menus to configure the parameters described below:
Parameter Description
State Toggle the State field to either enable or disable a given port or group of ports.
Speed/Duplex Toggle the Speed/Duplex field to either select the speed and duplex/half-duplex state of the
port. Auto denotes auto-negotiation between 10 and 100 Mbps devices, in full- or half-duplex.
The Auto setting allows the port to automatically determine the fastest settings the device the
port is connected to can handle, and then to use those settings. The other options are Auto,
10M/Half, 10M/Full, 100M/Half and 100M/Full. There is no automatic adjustment of port settings
with any option other than Auto.
Flow Control Displays the flow control scheme used for the various port configurations. Ports configured for
full-duplex use 802.3x flow control, half-duplex ports use backpressure flow control, and Auto
ports use an automatic selection of the two. The default is Disabled.
Learn Enable or disable MAC address learning for the selected ports. When Enabled, destination and
source MAC addresses are automatically listed in the forwarding table. When learning is Dis-
abled, MAC addresses must be manually entered into the forwarding table. This is sometimes
done for reasons of security or efficiency. See the section on Forwarding/Filtering for
information on entering MAC addresses into the forwarding table. The default setting is
Disabled.
Click Apply to implement the new settings on the Switch.
