CSM Sticky replication - how do you know if it is working?

I have two CSMs in a fault tolerant configuration.

If I do a "show module csm 2 conn" on the passive CSM, I can see the connections replicated between the CSMs.

However if I do a "show module csm 2 sticky" on the passive CSM, I cannot see the sticky data in the table. Is this normal, or is the replication not working?

I know I tested it in the lab, and I can't remember if I could ever see the sticky information in the passive CSM.

The config is below:

Re: CSM Sticky replication - how do you know if it is working?

Figured it out myself. I found that the sticky replication stopped after I did a config synch. This appears to be related to a known bug. I upgraded the code and it is now working.

Which CSM version you have? We have CSM V3.2. Will it have the same bug? Thx.
