Checking High Availability Status 147

If the backup Firewall has taken over for the primary, for example, in the

event of a failure to the primary Firewall, the first line in the status

window indicates that the backup Firewall is currently Active.

Check the status of the backup Firewall by logging into the LAN IP

Address of the backup Firewall. If the primary Firewall is operating

normally, the status window will indicate that the backup Firewall is

currently Idle. If the backup has taken over for the primary, this window

will indicate that the backup is currently Active.

In the event of a failure in the primary Firewall, you may access the Web

interface of the backup Firewall at the primary Firewall’s LAN IP Address

or at the backup Firewall’s LAN IP Address. The primary Firewall will not

be accessible until the primary Firewall has become Active again.

E-Mail Alerts

Indicating Status

Change

If you have configured the primary Firewall to send e-mail alerts, you will

receive an alert e-mail when there is a change in the status of the High

Availability pair. For example, when the backup Firewall takes over from

the primary after a failure, an e-mail alert will be sent indicating that the

backup has transitioned from Idle to Active. If the primary Firewall

subsequently resumes operation after that failure, and Preempt Mode has

been enabled, the primary Firewall will take over and another E-mail alert

will be sent to the administrator indicating that the primary has

preempted the backup.

View Log The Firewall also maintains an event log that displays these High

Availability events in addition to other status messages and possible

security threats. This log may be viewed with a browser using the Firewall

Web interface or it may be automatically sent to the administrator’s

e-mail address.

To view the Firewall log, click the Log button on the left side of the

browser window and then click on the View Log tab at the top of the

window. A window similar to the following will be displayed.
