VRA Manager as a Call Control Manager
AUTHENTICATION TIMEOUT TIMER
This timer represents the amount of time the CyberSWITCH will wait for the Authentication Agent
to handle a login attempt before timing out. If VRA is enabled as Call Control Manager, this time-
out value must then represent the amount of time for both:
• the Authenticating Agent to respond to the login attempt, and
• the VRA Manager to respond to the login attempt.

ALL CONTROL FAILURE BANNER
If VRA does not permit call connectivity for any reason, the CyberSWITCH will display the
message “VRA Manager Denied Access”. You may change this default message to whatever you
choose through this configuration element.
BACKGROUND INFORMATION
Cabletron’s Virtual Remote Access (VRA) Manager consists of an administration program and a
user interface, and runs with a database and a standard SQL server. It acts as both an authentication
server and call control manager for the CyberSWITCH. This product is described in detail in the
SecureFast Virtual Remote Access Manager User’s Guide which accompanies the product.
If you are interested in call control management without VRA authentication, the VRA Manager as
Call Control Manager is now an available feature. This feature provides call control management
with any authentication agent (e.g., RADIUS, ACE, TACACS).
To use VRA for call control management only, you must enable the feature. The call will be
authenticated through the chosen method, and then call control management will pass to the VRA
manager. Acceptable authentication methods are:
• RADIUS at device level
• VRA at device level
• RADIUS at user level
•ACE at user level
• TACACS at user level
• On-node Device Table at device level
In all cases, the device information is propagated into the CyberSWITCH from the authentication
agent. (This implies that IP static routes and IP pooling are configured on the CyberSWITCH, and
not the VRA manager.) When VRA is not the authenticating agent, the VRA Manager cannot
initiate outgoing calls. To make outgoing calls from the CyberSWITCH, you must use other means
of initiation, based on type of security (e.g., IP route lookup using RADIUS).
C
ALL CONTROL MANAGEMENT
VRA call control management varies depending upon the type of security in use:
• Device Level Security
If you use the On-node Device Table as authentication agent, VRA merely logs call start and
end times. (You do not need to configure devices in the VRA database).
If you use an off-node authentication server for authentication: configure devices on the VRA
manager as well. This will provide access to the following VRA call control management
features: call restrictions, maximum bandwidth, and grouping (in addition to the call logging
feature).
