VDS 6.0 - Determine output NIC from LACP Hash/Algorithm

We are currently building a vSphere architecture based for networking side on VDS and LACP aggregates under vSphere 6.0.

We are seeking a command/tips/whatever to determine the output NIC name choosed by a selected LACP algorithm (for outbound traffic of course, since the inbound link is selected by the switchs).

Example: for Source and destination IP address, TCP/UDP port and VLAN load balancing mode with the correct input (source IP / dest IP / Port / VLAN) and LACP ID the command will return which NIC from the LACP aggregate is used for routing the flow.

I think this might be usefull for debugging purposes...

Anyone know if such thing exists ?

If there is, it's not documented anywhere. Unlike Cisco, which has the hash-result command.

This article appears to be the most in-depth one covering VMware hash selection, and it only focuses on IP Hash: Troubleshooting Network Teaming Problems with IP Hash | Support Insider - VMware Blogs
