Persistence time-out and Connection time-out

Hello, Everyone

 

I have a one question.

 

I use tcp profile that has idle time-out 300 seconds and use source address affinity Persistence profile that has idle time-out 200 seconds.

 

  1. when I send data using connection for 300 seconds, is persistence table gone at 200 seconds ?

     

  2. Is persistence table re-created at 200 seconds ( I'm use connection continuously) ?

     

Thank you.

    The persistence table is constantly updated so if you maintain a connection with active traffic then you will see the persistence table being refreshed throughout the period of connection. You can see this in the GUI under the Persistence statistics and also at the CLI 

    tmsh show /ltm persistence persist-records

    My suggestion would be the persistence timeout be longer than the TCP idle time out.

    Hope this helps,
