Managing login permissions

You can manage login permissions to enable different privilege levels for each user and to
operate the security mechanism.

Security overview

The Avaya G250/G350 Media Gateway includes a security mechanism through which the
system administrator defines users and assigns each user a username, password, and a
privilege level. The user's privilege level determines which commands the user can perform.
In addition to its basic security mechanism, the G250/G350 supports secure data transfer via
SSH and SCP.
The G250/G350 can be configured to work with an external RADIUS server to provide user
authentication. When RADIUS authentication is enabled on the G250/G350, the RADIUS server
operates in conjunction with the G250/G350 security mechanism. When the user enters a
username, the G250/G350 first searches its own database for the username. If the G250/G350
does not find the username in its own database, it establishes a connection with the RADIUS
server, and the RADIUS server provides the necessary authentication services.
