Hi Tiaan,

 

 

Have you tested and found a problem? If so, could you elaborate on what you configured, tested and found?

 

 

As you quoted from the wiki page, I think PERSIST_DOWN will be triggered if the selected pool member has been "marked down". If a node is disabled, it will still accept requests from clients with a valid persistence record. So I wouldn't expect the PERSIST_DOWN event to be triggered. If the pool member is Forced Offline (Only active connections allowed), then I would think the event would be triggered.

 

 

Also, note that the solution describes a known issue with the triggering of this event:

 

 

PERSIST_DOWN is not triggered on failed persistence when cookie persistence or MSRDP persistence is the configured persistence method. F5 Product development is tracking this issue under CR104960 (SOL9115).
