There are five steps to configure High Availability feature.
Step 1. Set two DFL-1500 devices first. Remember to set the Action Mode for primary device as Active mode and
secondary device as Standby mode.
Step 2. When the primary device crashes, the secondary one will replace it within 30 seconds while detecting by “ping”
command.
Step 3. The secondary device will immediately load the configuration from primary device, and then change its action mode to
Active mode.
Step 4. After rebooting, the primary device will automatically change its action mode to Standby mode if it detects the
secondary device in active mode already.
Step 5. If both of primary and secondary devices crash simultaneously, the one which reboots faster will action as Active
mode, and the other will be in Standby mode.
27.4 Steps
27.4.1 Setup High Availability
Step 1. Enable High Availability
Check the Enable High Availability
checkbox. Select the Action Mode as Active if it
is the primary device and Standby for the
secondary device. And then configure the other
HA device. Select which interface to connect to.
Enter IP Address and Login Password.
Note that you have to configure the Secondary
device as Standby mode and the IP address/
Login Password of the Primary device, so High
Availability can work then.
