I had an issue with the sdwan, wan1 always state dead and the traffic isnt balance, more like 80 wan2 : 20 wan1 (i set 50:50 volume). I tried to research related the issue and find the wan1 overload. Is there any configuration to reset the volume or there might be an other issue?

Note : i did not upgrade the firmware from v7.0.16 to v7.0.17 and my alternative solution so far is make static to wan1 priority and set policy object to wan2 

 

Im begineer and try to gain more knowledge

@azizrizkyd Volume based method will take in account the Cumulative amount of bytes received on the interface and the interface weight when distributing the session to each member interface. Higher the value for weight and target volume, more sessions are distributed to it. So setting the volume ration 50:50 doesn't mean that they are equally distributed as it also accounts for the interface weight and also there is a possibility that one of the session has larger volume of data exchanged (elephant flows). Suitable option is to set the weight and volume percentage according to the available bandwidth of each link. In addition you could make use of SDWAN rules to route traffic to specific WAN interface based on different methods available in the interface selection strategy.
