does persistence is cleared for down pool member ?

Hi team,

 

i have a pool with 2 members enabled with persistence when one of the server A is down, does the persist connections are sent stil to server A which is down? I understand it should not but please confirm.

 

i have same setup with gtm wip as well does this same applies to gtm tooo ?

    Thanks Dareuja.

     

    I was wondering if the same case applies for gtm as well when applied with persistence.

    GTM persistence works different from LTM pools;

     

    see following:

     

    Persistence TTL: Persistence TTL specifies, in seconds, the length of time for which the persistence entry is valid. The default is 3600.

     

    Drain Persistent Requests

     

    Drain Persistent Requests is an additional global configuration that affects persistence behavior for all wide IPs with persistence enabled. Enabled by default, this setting is specifies that when you disable a pool or data center, load-balanced persistent requests will continue until the time-to-live (TTL) interval expires.
