Accessing the Avaya G450 Media Gateway

SCP configuration

Enter clear ssh-client known-hosts to clear the client's list of SCP server fingerprints.
Each SCP client maintains a list of server fingerprints. If a key changes, the client's verification
of the server's fingerprint will fail, thereby preventing the client's access to the SCP server. If
this happens, you can enter clear ssh-client known-hosts to erase the client's server
fingerprint list. This enables the client to access the server and begin to recreate its list of
fingerprints with the SCP server's new fingerprint.

RADIUS authentication

If your network has a RADIUS server, you can configure the G450 to use RADIUS
authentication. A RADIUS server provides centralized authentication service for many devices
on a network. When you use RADIUS authentication, you do not need to configure usernames
and passwords on the G450. When you try to access the G450, the G450 searches for your
username and password in its own database first. If it does not find them, it activates RADIUS
authentication.
For additional information on RADIUS configuration and authentication, go to the Avaya website
at http://www.avaya.com/support, and perform a search for the document Avaya G700/G350
RADIUS Configuration Overview, 104207.

Using RADIUS authentication

1. Configure your RADIUS server with the usernames, passwords, and privilege levels that
you want to use on the G450.
2. Configure RADIUS authentication on the G450.

Configuring RADIUS authentication

1. Enter set radius authentication enable to enable RADIUS authentication.
