Small Office Remote Access Switch 313C ONFIGURING C ALL C ONTROLVRA Manager as a Call Control ManagerA UTHENTICATION T IMEOUT T IMERThis timer represents the amount of time the CyberSWITCH will wait for the Authentication Agentto 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.CALL CONTROL FAILURE BANNERIf VRA does not permit call connectivity for any reason, the CyberSWITCH will display themessage “VRA Manager Denied Access”. You may change this default message to whatever youchoose through this configuration element.BACKGROUND I NFORMATIONCabletron’s Virtual Remote Access (VRA) Manager consists of an administration program and auser interface, and runs with a database and a standard SQL server. It acts as both an authenticationserver and call control manager for the CyberSWITCH. This product is described in detail in theSecureFast 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 asCall Control Manager is now an available feature. This feature provides call control managementwith any authentication agent (e.g., RADIUS, ACE, TACACS).To use VRA for call control management only, you must enable the feature. The call will beauthenticated through the chosen method, and then call control management will pass to the VRAmanager. 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 levelIn all cases, the device information is propagated into the CyberSWITCH from the authenticationagent. (This implies that IP static routes and IP pooling are configured on the CyberSWITCH, andnot the VRA manager.) When VRA is not the authenticating agent, the VRA Manager cannotinitiate outgoing calls. To make outgoing calls from the CyberSWITCH, you must use other meansof initiation, based on type of security (e.g., IP route lookup using RADIUS).C ALL C ONTROL M ANAGEMENTVRA call control management varies depending upon the type of security in use:• Device Level SecurityIf you use the On-node Device Table as authentication agent, VRA merely logs call start andend 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 VRAmanager as well. This will provide access to the following VRA call control managementfeatures: call restrictions, maximum bandwidth, and grouping (in addition to the call loggingfeature).
