Avaya P332GT-ML User’s Guide
All transactions between the RADIUS client and server are authenticated through 
the use of a “shared secret” which is not sent over the network. The shared secret is 
an authentication password configured on both the RADIUS client and its RADIUS 
servers. The shared secret is stored as clear text in the client’s file on the RADIUS 
server, and in the non-volatile memory of the P330. In addition, user passwords are 
sent between the client and server are encrypted for increased security.
Figure 8.1 illustrates the RADIUS authentication procedure:
