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.
