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
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
.
