The next step involves editing the RADIUS server’s user data file (called the

Users file). Since different RADIUS servers implement their security features

differently, this FAQ will provide only a general answer to cover most RADIUS

servers. In RADIUS, each user must have a Service-Type of “Framed” and

Framed-Protocol of “PPP.” Add the attribute Framed-IP-Address to each user

entry, if it doesn’t exist. If a user requires a static address, set Framed-IP-

Address to the static address. Otherwise, set Framed-IP-Address to

255.255.255.254. This “address” tells RADIUS to let RASExpress assign the

user an IP address. RASExpress will assign the user an address from its

address pool.

Q55. How do I set up my RADIUS server to communicate with my

CommPlete’s RASExpress servers?

A55. Since different RADIUS software vendors implement their security features

differently, this FAQ can only provide a general answer. In RADIUS, a RAS

server is considered to be a “client” of the RADIUS server. Each client, when it

sends an authentication request to RADIUS, must provide a Shared Secret,

which is essentially a password that only the RAS server and RADIUS server

know. When the RADIUS server receives an authentication request, it checks its

client database to validate the RAS server. In most cases, the client database is

contained in a file called Clients, where the IP addresses and the Shared Secrets

of valid clients are stored. If the RADIUS server receives a request from a client

that does not exist in the Clients file, the RADIUS server discards the request.

Q56. How do I distinguish a problem with the CommPlete Server

from a problem on the network to which it is connected?

A56. There are three questions that you can ask yourself when troubleshooting this

situation:

1. Are any devices on the network having the same trouble that the CommPlete

is having? If so, then the problem is most likely on the network, not the

CommPlete Server.

2. If the CommPlete Server is disconnected from the network, does the problem

disappear from the network? If so, then the problem most likely lies in the

CommPlete Server.

3. Were any changes made to the network prior to the problem occurring?

Check the history of the network before the problem appeared to find out if

any changes were made to the CommPlete Server or the network. This will

narrow your search for the cause of the problem.

Q57. What do I need to do as pre-installation site preparation?

A57. There are two resources that you should refer to before installing your

CommPlete Server. First, the CommPlete Documentation Set includes a System

Installation and Quick Start Guide. Read through this guide to determine which

settings are affected by the network and by the T1 or PRI line(s) you have

installed or have ordered. Second, read the CommPlete Site Planning Guide

found on the CommPlete Resources web page at
