port bonding LACP information needed

[Johnny Wong]

My understanding is that SONiC port over teamd for network bonding.  But I am unable to find what algorithm it is using and if it is possible to change the load balancing algorithm.  

Can anyone point me to the right direction?

There are different types of runners and load balance is also included

According to the content of https://github.com/Azure/sonic-buildimage/blob/master/src/sonic-yang-models/yang-models/sonic-portchannel.yang

Currently SONiC config would only support lacp runner. If you would like to use other type of runner, you can enter the team container and use 

teamdctl to launch a new portchannel

would it be beneficial for the community to request a feature where the administrator be able to change teamd in a more configurable/automated way?

I am running into an issue (or limitation) where I need to bond two links possibly three links in VMWare environment.  But it only support 802.3ad in STATIC mode.

Like to revisit this... as I have found out that SONiC only does L2 and L3 and not L4.  But I couldn't figure out how to add L4 to the configuration
