Priority Group

Hello Chaithy,

Based on this article https://support.f5.com/csp/article/K13184

Beginning in BIG-IP 10.1.0, the default value for the Priority Group setting is 0 when a pool member is added to a pool. When a pool member has its Priority Group setting assigned 0, the pool member will have the lowest priority. If a pool has Priority Group Activation enabled and all of the members in the same pool have their Priority Group setting assigned 0, all of the members will have equal priority.

If you activate the "Priority Group Activation" on the Pool, and you didn't changed the default "Priority Group" of some pool members, they will have the lowest priority. So they will handle the traffic if no pool member are UP with a higher priority group.

Hope it helps

Regards
