L. Device HA FAQ

L01. What does the "Preempt" mean?
The "Preempt" means that the Backup with high priority can preempt the Backup with low
priority when the Backup device is online. And Master can always preempt any Backup.

L02. What is the password in Synchronization?

If the Backup wants to synchronize the configuration from Master, both Master and Backup
device must be set the same password.
L03. What is "Link Monitor" and how to enable it?
A new feature enhancement Link Monitor in ZLD 2.0x series. By enabling "Link Monitor"
option, the ZyWALL monitors link status of direct-connected cables constantly. If a master
ZyWALL VRRP interface's link is down, the faulty VRRP interface on master's router remains
in status active and the rest of VRRP interface(s) on the master router will turn into fault. The
purpose of this design is to prevent the backup router interface in the same VRRP group
cannot detect the faulty event encountered on the master router.
You can click on Device HA from the left panel and check the "Enable" checkbox to enable
the link monitor.
