There may be times when you need to troubleshoot a survivable core server implementation. To determine what is causing a fault it is important to understand the following:

• The layout and topology of the network

• Where survivable core servers are located on the network

• How you want the design to work during the failure

You can obtain this information from the implementation team or the customer.

By looking at the translation of a particular Survivable core server installation, you can make reasonable predictions as to how the installation will react to server failure and/or a network failure. However, keep in mind that the way the various components are configured and translated may not reflect the original intent of the network design.
