Traffic-Group Behaviour
I have been testing traffic-group on my vLabs and I still do not quite understand the behaviour during failover times. The vLab I am working on has the following configuration:
- BIGIP_A - Traffic-Group-A
-
BIGIP_A - Traffic-Group-B
-
BIGIP_B - Traffic-Group-C
- BIGIP_B - Traffic-Group-D
This configuration makes both devices become an Active-Active pair, which is fine. I expected that. I have added virtual addresses objects on all traffic-groups for testing purposes and enabled SNAT auto-map as well. The question I have is regarding the failover between them. When I simply unplug the network cable, the traffic-groups are not floating to the other device; however, if I power the device off, the traffic-group floats right away. The only situation, which I managed to make the traffic-group to failover after unplugging the network cable is by enabling the VLAN-Failsafe feature, which then automatically failover the traffic group to the other device.
Can someone explain the reason for such behaviour or if it is just he way it supposed to be?
Thanks
