Deploying Device Ha Pro; Configuring Device Ha Pro - ZyXEL Communications ZyWall ATP series User Manual

After failover, the initial active Zyxel Device becomes the passive Zyxel Device after it recovers.

35.3.1 Deploying Device HA Pro

Register either the active or passive Zyxel Device with a Device HA Pro license at myZyxel. Check that it's
1
properly licensed in Licensing > Registration > Service in the active Zyxel Device.
Make sure the passive Zyxel Device is offline, then enable Device HA in Device HA > General in the
2
passive Zyxel Device.
Must make sure the FTP port in System > FTP (default 21) is the same on both Zyxel Devices. FTP is used for
3
transferring files in the event of failover from active to passive Zyxel Device.
Connect the passive Zyxel Device to the active Zyxel Device using the highest-numbered ports on both
4
Zyxel Devices. This is the heartbeat interface. Make sure that this interface is not already configured for
other features such as LAG, VLAN, Bridge.
If both Zyxel Devices are turned on at the same time with Device HA enabled, then they may send the
5
heartbeat at the same time. In this case, the Zyxel Device with the bigger MAC address becomes the
passive Zyxel Device.
When using Device HA Pro to synchronize firmware, the location of the running firmware must be the
6
same in both active and passive Zyxel Devices. For example, if the running firmware is in partition 1 in the
active Zyxel Device (standby firmware in partition 2), then the running firmware must also be in partition
1 in the passive Zyxel Device (standby firmware in partition 2).
