Can someone describe the load balancing algorithm used for Aggregate links?

Not applicable

Reading the documentation and forum posts, it doesn't appear that the PA is using LACP, therefore, it's not using one of the 3 common LACP load balancing algorithms.

Could someone describe how it's making the decision to send traffic down a particular link?  Also, am I able to modify the behavior?  (it doesn't seem like I can through the web interface).

Thanks!

Hi..You are correct and we don't support LACP at this time.  We only support static link aggregation.  To connect to other networking devices, simply set LAG to be static.  Thanks.

So as of today PAN only use srcmac+dstmac as transmit hash?

Which gives that if you setup PA <- 2 cables -> switch <-> server only one of the cables will be used for traffic from PA to the server?

Would be great if this can be tweakable in future updates to at least involve a transmit hash such as srcip+srcport+dstip+dstport for added utilization of the available links in the aggregated group.

Do you have an ETA on when LACP or L4 hashing will be implemented?  I've had several clients bring up the issue.

Please check with your local Palo Alto SE for update on upcoming features.  Thanks.
