356 EPICenter Software Installation and User Guide
Administering EPICenter
• Administrator — users who can create, modify and delete user accounts as well as perform all the
functions of a user with Manager access.
The EPICenter server provides two default users:
• “admin” with Administrator access
• “user” with Monitor access
The two default users do not initially have passwords. All other user names must be added and enabled
by an Administrator user.
Regardless of your access level, you can run the Administration applet and change your own password.
Users with Administrator access can add and delete users and assign user access levels.
NOTE
The EPICenter user accounts are separate from the Extreme switch user accounts. You can configure
both through the EPICenter software, or you can have switch access independently of the EPICenter
software.
ExtremeWare Software Access
Through the EPICenter software, two levels of access to Extreme switches can be enabled:
•
User — Users who can view device status information and statistics, but cannot modify any
parameters.
• Administrator — Users who can modify device parameters as well as view status information and
statistics.
These permissions enable access to Extreme Networks switches through Telnet or ExtremeWare Vista.
The use of the RADIUS server avoids the need to maintain user names, passwords, and access
permissions in each switch, and instead centralizes the configuration in one location in the EPICenter
server.
The EPICenter RADIUS Server
The EPICenter software incorporates a basic RADIUS server for user authentication. RADIUS provides a
standard way for the EPICenter software and Extreme Networks switches to handle user authentication,
permitting the unification of the Extreme Networks CLI, ExtremeWare Vista, and EPICenter user
authentication. The EPICenter server can be configured to act either as a RADIUS server or a RADIUS
client. RADIUS authentication is disabled by default.
ExtremeWare versions 4.1 and later support the RADIUS server for authentication and can act as
RADIUS clients.
Setting EPICenter Server Properties
The server properties interface allows an EPICenter administrator to modify a number of parameters
that affect server performance and function. These include communication parameters such as polling
intervals, time-outs, port usage, number of retries, setting Scalability mode, and a number of other
parameters.
