TERMINAL SERVERS
Step 2: Define Port as Dedicated PPP and Enable it
Statement 2 specifies that the port will be attached automatically as a PPP host
when the user logs on to the Terminal Server. DEDICATED prevents the user
from using the port as a terminal port and negates the need for any character-
mode communication—except the user name and password (if needed). This
simplifies the script required to connect the PPP device to the Terminal
Server.
Statement 3 enables the port to work in PPP mode. To enter PPP mode, the
user issues a “CONNECT PPP” command or uses the Dedicated definition as
in statement 2. After starting the PPP mode, the Terminal Server will expect
only PPP frames from the attached device.
Step 3: Define the Port Flow Control
We recommend that you disable flow control for directly-attached devices
with PPP connections, such as when a modem is used. Command 4 disables
the flow control that is implemented in any case by the PPP itself.
Step 4: Define the Port IPCP Address
Statement 5 configures the IP address of the port. The IP address can be
configured in one of three different methods:
• Configuration using the Terminal Server command language
(as in this example)
• Configuration by a RADIUS server
• Learning during IPCP negotiation with the connected device
Step 5: Define the port user name
Statement 6 defines a permanent username to the port eliminating the
request-prompt usually displayed when the user logs in. This setting is
overridden if the port log-in is to be authenticated by a RADIUS server.

The following example shows some additional and more advanced settings
available for a PPP defined port. In this example, the same Terminal Server as
in the previous example is configured for a modem connection, but also has
additional settings to restart the LCP protocol if the connection restarts and
