NIC Teaming not working with Cisco Etherchannel

[sreeve3939]

Simple setup: NIC Teaming on vSwitch0 connected to a Etherchannel on the Cisco side.

Etherchannel spans two Cisco devices.  

All vSwitch0 failover looks like this:

All works good on the esxi hosts using Mellanox adapters.

However, NIC teaming not working on hosts using Broadcom 57414 adapters (at least that's the only difference that we can see)

ICMP Echo requests come in on vmnic0 and are not answered:

Not sure why esxi doesn't send the ICMP Echo Reply.

4 hosts with Mellanox adapters work fine.

2 hosts with Broadcom 57414 adapters: no ICMP Echo Reply.

Not sure how to proceed - looking for some ideas.

Will it work with just one nic that is not teamed ? Do you have the approved driver for your ESXi version ?  I've never used those, but its one of those things that just should work, right ?

Just a guess.
Can you confirm that the physical switch ports are configured exactly the same?
I ran into an issue that I did not expect, where flow control was configured differently on the ports.
