C ONFIGURING C YBER SWITCH - U SER G ROUPS
OVERVIEW
Groups of CyberSWITCH systems and users may be configured, in order to allow the SFVRA
Connection Manager to better manage its devices. By grouping the CyberSWITCH systems and
users, you can not only limit which users can call which CyberSWITCH, but you can manage which
CyberSWITCH can call which users. This can reduce costs by eliminating calls from CyberSWITCH
systems that may not have the cheapest direct connection to certain users.
A CyberSWITCH may only belong to one group. However, users may be a part of many groups.
There is no limit to the number of CyberSWITCH systems or users in a group. CyberSWITCH
systems and users that do not belong to any group are classified by SFVRA-CONN into a group
with no name, designated by <No Group>.
Only devices of the same group may call each other. If a user attempts a connection to a Remote
Access Switch not in its group, SFVRA-CONN will reject the call and enter in the database Problem
Log table an entry with the Failure Type “Connect Failed” and the Reason “User not part of this
group.” For outgoing calls, SFVRA-CONN determines to which user the call is to be made and then
searches the database for a Remote Access Switch in the same group. If there is no Remote Access
Switch in the group, SFVRA-CONN will not make the call and enter in the database Problem Log
table an entry with the Failure Type “Connect Failed” and Reason “No Remote Access Switch for
this users group.”
Note: Configuring a user in multiple groups can adversely affect the behavior of the network.
Users that are remote hosts and are dynamically assigned an IP address should not have a
problem. SFVRA-CONN will not check for the following situations where problems may
occur.
1. A user that is a RLAN attached bridge with a permanently assigned IP address. This
address would only be relevant to a single-site CyberSWITCH.
2. A user that has static routes configured and these routes are being advertised by
multiple systems without the SFVRA RIP service being used.
3. IP users with call out enabled will have their routes advertised by multiple groups.
Multiple CyberSWITCH systems may try to reach the user at the same time.
Groups may be assigned individually to devices within the configuration utilities of the SFVRA
Connection Manager for the CyberSWITCH or the user. Refer to CyberSWITCH Properties or
Grouping Users for more information. Groups may also be assigned collectively on the
CyberSWITCH - User Groups configuration utility, as described in the following sections.
