Configuring The Console Port Of The Switch - IBM 8271 Nways F12 User Manual

Configuring the
Console Port of the
Switch
Half Duplex Flow Control Enabled / Disabled
Allows you to enable or disable the Intelligent Flow Management flow
control that can be used when the port is operating in half duplex.
Flow control prevents any packet loss that may occur on congested
ports.
The Half Duplex Flow Control field should be disabled if the port is
connected to multiple devices using a repeater.
Port State Enabled / Disabled
Allows you enable or disable the port (that is, turn the port on or off).
Security Enabled / Disabled
Allows you to specify whether the port uses Security to guard against
unauthorized users connecting devices to your network. When Security
is enabled on a port, it enters Single Address Learning Mode. In this
mode, the Switch removes all the MAC (Ethernet) addresses stored for
the port in the Switch Database and then learns the address of the first
packet it receives on the port.
Once the first address is learned, no other endstation is allowed to
access the network through the port. If an endstation with a different
address attempts to transmit packets through the port, the port is
automatically disabled until it is enabled using the Port State field.
By default, the console port is configured for direct connection to a
terminal. You only need to change this configuration if you are
connecting a modem to the port. You can configure the console port
of the Switch using the Console Port Configuration page.
To access the page:
1 Click the Unit icon on the side-bar.
2 Click the console port on the Switch graphic. The Console Port
Configuration page is displayed as shown in shown in Figure 4-10.
