As choose the F5 BIG-IP device to Active?

Hi guys;

 

Good day, I am new to the F5 platform, so I have the question of how make the F5 to select the Master or Active device. This in a configuration of Active-standby redundancy.

 

I have the following:

 

BIG-IP01 ==> device currently in production and working properly. BIG-IP02 ==> Recently purchased device

 

All the parameters described in the guide was successful. In both devices. - Licensing and provisioning the BIG-IP system - Configuring a device certificate - Configuring the management port and administrative user accounts - Enabling ConfigSync and high availability - Configuring the internal network - Configuring the external network - Configuring the network for high availability - Configuring a ConfigSync address - Configuring failover and mirroring addresses - Discovering a peer device - Configure device group

 

But the problem is always the BIG-IP 02 is the one who puts as the active device and the BIG-IP01 is set as Standby. But that is not desired.

 

When the BIG-IP02 is placed as active at the time of arming redundancy, overwrites the configuration to BIG-IP01.

 

Therefore, the query is, that F5 takes to set parameters to a device as master or active.

 

Regards, John

    Until you have everything configured and working as expected I would suggest you not allow automatic syncing. To make the current standby device active, you must go to the active unit and click force to standby. You can find this under Device Management, Devices, .

     

    If the device will not remain standby you have configured something incorrectly for the desired behavior, or you have a communications issue between the boxes.
