Can you schedule Load Balancing on LTM?

I don't think it can be done, but I was asked if there is a way to schedule load balancing so that the LTM will only load balance across the pool at specific dates/times?

 

 

Thanks!

    Scheduling is not built into the GUI, but you could build an iRule that used the "clock" command to build logic around times. You could tailor the LTMMaintenanceWindow entry in the CodeShare to do specific load balancing during time windows and disable it during others.

    Hi,

     

     

    You can check "SOL119: Terminology: persistence" for details on persistence:

     

     

    https://support.f5.com/kb/en-us/solutions/public/0000/100/sol119.html

     

     

     

    Often described as the opposite of load balancing, persistence ensures that once a client is load balanced to a node, all future connections from that client are directed to the same node.

     

     

    Persistence is required to successfully track client information. The most common application for persistence is in electronic commerce sites, where a client that is initially directed to a particular node address for HTTP requires a connection to the same node address for HTTPS.

     

     

    Persistence is offered in a several different forms on BIG-IP and 3-DNS.
