Persistence and system conection

show sys connections | grep a.b.c.d does not show the user with the IP address a.b.c.d to be connected through LTM. But when I check the persistence record, this IP is shown in the results. I have used source address affinity for persistence.The connection persists for the time set in the persistence profile but during all this duration, the user connection does not get listed. I am not sure what I am missing, please suggest.

  • The connection record shows existing connection. If the connection no longer exists, you won't be able to see it in the "show sys conn" output.

     

    Persistence table can hold records even after the connection is dropped depending on timeout interval for that persistence record. So, a connection that is no longer active will not exist in the connection table but can exist as a persistence record in the persistence table till the persistence timeout is reached.

     

    When the same client IP initiates a connection before the persistence timeout, it will be sent to the same backend server based on the persistence record.
