self IP's, floating IP's and config sync

New to the F5 world. I'm learning the product by putting documentation and experience together with setting up F5 LTM 11.3 from installation to configuration in our lab environment.   The end goal...

Josh,

 

QU. What does config sync actually sync? I've read it sync's only the self/floating IP's to the other. I guess it doesn't include virtual server configs?

 

Ans. It syncs shared configurations, so floating self-ips and listener objects like virtual servers, snats, nats etc. And, of course, the configuration objects that make up these objects e.g. nodes/pools/monitors etc.

 

QU. Once configsync is done, shouldn't I see all the configs on the standby device?

 

Ans. Yes

 

QU. Do I need to create the virtual servers on both LTM's in order to have the standby to take effect?

 

Ans. the config sync process will do this but, yes, you need the same VS configuration on both boxes.

 

Check out askf5 for terms like DSC (HA basically) and traffic-groups (what is logically shared between bigips).

 

Hope this helps,
