4-82 MAX 6000/3000 Network Configuration Guide
Configuring Individual WAN Connections
Configuring terminal-server connections
Following is a sample RADIUS profile:
tcpapp1 Password = "localpw"
Service-Type = Login-User,
Login-Service = TCP-Clear,
Login-IP-Host = 10.10.10.1,
Login-TCP-Port = 23,
Login-IP-Host = 10.10.10.2,
Login-TCP-Port = 125
TCP-modem connections (DNIS Login)
The TCP-modem feature enables the MAX unit to accept connections through the Ethernet
interface though as they were modem connections. You can enable or disable TCP-modem
access to the unit, and you can configure the default port for TCP modem access. You can
disable TCP-modem connections to the unit. In addition, you can change the TCP port used for
these connections. The default port for TCP-modem is 6150.
Figure 4-15 illustrates an example of a TCP-modem setup. A user dialing into an ISP first
connects to the telephone switch and then establishes a connection to MAX 1. MAX 1 has a
TCP-Clear connection configured in RADIUS to a unit at an ISP. Typically, this connection is
over Frame Relay. The remote user appears to be directly connected to the ISP MAX. MAX 1
merely passes the data through. The ISP MAX typically authenticates remote users.

The terminal-server interface
The terminal server can provide a command-line interface (terminal mode) or a menu of Telnet
hosts that dial-in users can log into (menu mode). Or, you can configure an immediate mode to
automatically present the user with a login prompt to a host, bypassing the terminal-server
interface altogether.
Terminal mode
In terminal mode, users have access to the command line and can see information about your
network by using administrative terminal-server commands. You can also enable them to
initiate their own Telnet, Rlogin, or TCP connections to hosts.
