294 Advanced configuration Establishing high availability failover restart also fail, then Symantec Network Security shifts or fails over to the standby node. Watchdog processes are advanced configurations that employ advanced parameters. Make sure that sufficient RAM exists on the system. When deploying failover groups, keep in mind that the failover system is designed to work best for nodes that have a fast, reliable network interconnection between their administration interfaces. An example configuration would be two nodes in close proximity, connected through the Ethernet. Note: Do not confuse failover with fail-open, which is the state that permits (fail-open) or blocks (fail-closed) traffic from flowing through a sensor that is placed in-line with a firewall. Note: SuperUsers can configure watchdog processes; Administrators, StandardUsers, and RestrictedUsers cannot. See "User groups reference" on page 319 for more about permissions. Set up and enable watchdog processes by configuring the following parameters: ■ Setting Enable Watchdog Process ■ Setting Watchdog Process Stop Window ■ Setting Watchdog Process Maximum Resets ■ Setting Watchdog Process Restart Only ■ Setting Watchdog Process Email Setting Enable Watchdog Process Enable Watchdog Process serves as the on/off switch for the watchdog process.
