Two agents will be running on the Active and Redundant servers, "stunnel" and
"VMSWebServer." Make sure they are not blocked out by your firewall. These agents can be
found in the default folders below:
C:\Program Files (x86)\VIVOTEK Inc\sTunnel\stunnel.exe
C:\Program Files (x86)\VIVOTEK Inc\VAST\Server\VMSWebServer.exe
Click on the Add button to create a Redundant server group. The Active and Redundant
servers you enlisted on the Sites page should all be listed below. Select the members of the
Redundant group, and click Add to complete.
The default for the network disconnection timeout is 30 seconds. It is not recommended to
configure a very short timeout, e.g., 5 seconds, because if doing so, a temporary network
disorder can make servers consider the Active server(s) have failed.
