Load balancing method & Priority group activation

Hi,

 

I started learning LTMs and have the following question:

 

let's suppose that I have a pool has 2 members that is configured as following:

 

Load Balancing Method: least connection

 

Priority Group Activation : less than 1

 

Member A priority 2

 

Member B priority 1

 

How is the loadbalancing going to work in this case ? is it going to load based on least connection or will start withbased on priority group and when it reaches the priority group condition it will start looking at the least connection ?

 

Thanks

  • The 'least connection' LB method will not have any affect since only 1 node exist in each priority group. As long a member A is up it will only us that. If A is down it will only use member B.

      Hi Chad, thanks for the answer, but what if I choose LB method to Round Robin ? will that change the behavior ?

      Nope, you need more than 1 active member for any of the LB methods to matter. Nothing to LB if you only have 1. If you want to use both of those nodes either put them in the same Priority group or turn Priority Group activation off.
