By default, the Failover system nodes use all available network interfaces. 

To limit the number of the used network interfaces, do the following:

  1. Add the following parameter to the C:\Program Files\Grundig\C-Werk\bin\raft\raft-settings.xml file:

    <item key="NGP_IFACE_WHITELIST">172.17.0.0/16</item>


    Use the following interfaces setting format: "IP-address1/number of unit bits in the mask, IP-address2/number of unit bits in the mask".

By default, the stale mode is activated to reduce the network traffic and the load on the CPU. In this mode, any Server in the Failover system can process queries, regardless of whether it is the master Server.

To disable the stale mode, do the following:

  1. Change the value of the following parameter to 0 in the C:\Program Files\Grundig\C-Werk\bin\raft\raft-settings.xml file:

    <item key="SVISOR_CONSUL_STALE_MODE_THRESHOLD_MS">0</item>

To activate the stale mode, change the value of the parameter to 200 in the file.

Note

Effective work in the stale mode is performed in the clusters with a large number of added Servers.
