NimbostratusLTM to GTM communication - difference in big3d versions
Hi All,
Quick question on bigd3 versions.
LTMs are running on 11.6.1 and the GTM is on 11.6.0. These are upgraded a hour ago, at the moment I'm seeing no errors. But as they are in different versions, will the GTM marks the LTM as down in future.?
GTM:
[root@DC1-f5g1:Active:Standalone] config /shared/bin/big3d -v
/shared/bin/big3d version big3d Version 11.6.0.4.0.420 for linux
LTM:
[root@DC1-f5l2:Standby:In Sync] config /shared/bin/big3d -v
/shared/bin/big3d version big3d Version 11.6.1.0.0.317 for linux
Please suggest me how to fix this, I have around 85 application on this LTMs, I don't want this big3d version differences cause any issues.
thanks
Bart_18836Recommendation is actually to have same big3d version on both :

Personally I had different versions running on my VEs but I havent found any issues but do not risk it. You can force update of the bigip3d but I did that only from GTM to LTM not other way around :

If you are unsure what to do you can always check with F5 support.

From SOL13703:
DNS/GTM/BIG-IP communication
Monitored BIG-IP systems must run the same or newer big3d version as the DNS / GTM devices that are monitoring them.From an experience perspective, I have updated LTM first before upgrading GTM. To prevent any unforeseen issues, you are better off upgrading the GTM asap.
GLM_191985Per my experience upgrade your GTM asap
