Forums Technical Forums
1

we have a requirement for Application server SLB as below mentioned scenario

Server-A and Server-B will be in the pool member

Server-A will be active and Server-B will be standby in the pool Member

if Server-A goes down the traffic will go on Server-B and  the traffic could not switch back if Server-A will comes online again. the switch back can happen only if the server-B goes offline.

is there any possibility to achieve the above scenario in BIG-IP LTM.

Hi, 
First, you need to configure Priority Group activation: myF5

This is a great feature when you want apply ( Active/Standby ) scenario on Pool level.

secondly:

you need to enable Manual resume feature to prevent the traffic from being return to the down pool member when it become up again, this feature is configured on health monitor level , so I recommend to create a customized health monitor instead of the default one. 
Here the Manual Resume feature: myF5

IF you don’t want this solution however I recommend to proceed with my first approach , but there is an irule to do that , please review this Article on DevCenteral: Priority Group Activation ( Preemption question) | DevCentral

Thanks
