Persistence question

Hi,

 

 

Let say that I have1 VS and 4 nodes in the pool + source persistence.

 

Let say that all nodes are going down and us again.

 

Is the persistence table will be flushed, or the nodes will go back and connections will be handled as were before the nodes/VS were down?

 

 

I'm 99% that the persistence table will be flushed for a node the went down.

 

I don't know the details since they might use persistence timeout instead?

    Hi Lipos,

     

     

    I believe that once a pool member is marked down, LTM removes all persistence table entries pointing to that pool member. I tested this on 10.1.0 with UIE persistence and saw the entries removed. I haven't done the same test with source address persistence, but I expect the behavior would be the same.
