VMware ESXi, 6.7.0, 15160138.
Earlier many of us had issues with Intel X710 nics having a hardware LLDP agent that made LLDP unavailable from the VMware side of things. There is a similar issue with broadcom nics, but LLDP works fine from the VMware side. From the switch side it does however get announments both from VMware and from the nic itself. While VMware's LLDP agent transmits both the server hostname and vmnic, the hardware nic agent only transmits the physical mac address.
It looks like different switch vendors handle this scenario differently. Cisco seems to only store the last value it received while Arista stores both values.
As we can see here, also from the Arista management UI we see that the MAC address is listed first and in many views only the first line is used.
As far as I can tell there is no parameter available in the ESXi 6.7 bnxtnet driver to disable LLDP in the same way we could on Intel x710:
] esxcli system module parameters list -m bnxtnet

Just encountered this on a VxRail installation. Did you find a solution?
Hi
Just disable "LLDP Nearest bridge" in NIC device settings in server's BIOS
WBR,
Oleksiy
Thanks! I've run into this issue and will try your advise
