See this link and search for the section on priority based member activation.

 

http://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm-concepts-11-4-0/5.html?sr=31994673

 

Basically all traffic would go to the member with higher priority unless it goes down.

 

thx

    Thanks again. According to that link "members that are assigned a high priority receive all traffic until the load reaches a certain level or some number of members in the group become unavailable". If I knew what "a certain level" meant... but I guess the "Priority group activation" applies - if set to 0 then traffic only fails over to lower (1) prio groups when *all* servers in high (99) prio groups are unavailable.
