Configuring Servers
An organization can establish a Terminal Access Controller Access Control
System () server to provide centralized security for all of its devices. In
this way, authentication and authorization can be handled on a single server for all
devices in the organization.
The switch can act as a client that uses the server for the
following services:
•
Authentication
—Provides authentication of administrators logging onto the
switch by using usernames and user-defined passwords.
•
Authorization
—Performed at login. After the authentication session is
completed, an authorization session starts using the authenticated
username. The server then checks user privileges.
The protocol ensures network integrity, through encrypted protocol
exchanges between the device and the server.
is supported only with IPv4.
Some servers support a single connection that enables the device to
receive all information in a single connection. If the server does not
support this, the device reverts back to multiple connections.
Use the page to configure the servers and define the default
parameters that are used for communicating with all servers. A user
must be configured on the to have privilege level 15 to be granted
permission to administer the switch.

Key String
—Enter the default key string in encrypted or plaintext form used
for communicating with all servers. If you do not enter the default
key string here, the key entered on the Add page must match the encryption
key used by the server. If you enter the default key string here and
a key string for an individual server, the key string configured for
the individual server takes precedence.
