Regarding timeout and persistence value

Hi All,

 

I am confused with tcp and session persistencetimeout values.. In LTM we are defining 5 min as timeout while persistence timeout value is either defined manually or it expires with browser closing.. So I am confused if the session is idle for 5 min will the LTM delete the connection and persistence record or it will just delete the session from session table and keep the persistence record?

 

thanks.

    Hi,

     

    • tcp timeout is for tcp connection. It is like the connection table in firewalls.
    • persistence record is to store selected pool member for next tcp connection. this record is stored in LTM memory. the timeout is to clear old records and reduce RAM usage.
    • cookie persistence is to store selected pool member for next tcp connection. this record is sent by the LTM in a cookie. no record is stored in LTM. As records are not stored in LTM RAM, the record can be stored indefinitely until the browser is closed.
