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:

Figure 6- 4. Port Configuration window

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 <Enabled>

Toggle the State field to either enable or disable a given port or group of ports.

Speed/Duplex <Auto>

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 Disabled, 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.
