Hi Extreme Community,

We followed the configuration from manual, but when we tried, the Synchronization is successful in status but nothing config from Primary has been sync to Standby ADSP Controller. Please help 

It only downloaded a sync file after clicking the sync now.

Can you share a screenshot like the one below from your redundant appliance

Hi Robert,

I already disabled the config backup from standby ADSP, then type the correct synchronization details.
I tried to test if it is working by click "sync now" and also tried to scheduled sync. Still it doesn't work.

Please see screenshot below for the status:

Make sure that the backup appliance has ip route to the primary, as there is a keep-alive between the two appliances. if they can not talk to each other then you will have issues as you do. 

login to the backup appliance via CLI 
type in "letmeout"
then see if you can Ping the primary appliance, do the same from the primary

Hi Robert,

Yes, they have network reachability. Please see below screenshots from cli>letmeout>PING each ADSP.
Primary-192.168.254.111
Standby-192.168.254.112

They are actually installed on the same VMware.

In the config screenshot, you used to open this thread the IP address is different "192.168.24.50", maybe this is the issue since your IP addresses are 
Primary-192.168.254.111
Standby-192.168.254.112

Hi Robert,

Sorry to confuse. I have actually two different Lab. The first screenshot is the configuration from the first lab secondary ADSP. 
I experienced the same on my two different ADSP lab. 

What is the expected behavior of Secondary ADSP once successful synchronization?
When scheduled synchronization is successful, is it automatically copy the configurations from the Primary? or do we need additional manual steps?

After the sync completes the redundant appliance copies the config from the primary and restores it. 

The proper way to synchronize servers is to configure your primary server first and then synchronize your secondary server with your primary server. All configuration settings are copied from your primary server to your secondary server so that the two servers have the same configuration. Configuration settings from the primary server will override any configuration settings on the secondary server.

Hi Robert,

Our synchronization issue is now resolved. We corrected the date and time of the controllers and it worked. Thank you so much.

Best Regards,

Gerald
