LLDP information is not shown on Bare Metal Edge configured with Intel 810 XXV Nics with enhanced data path enabled

Products

• VMware NSX

Issue/Introduction

LLDP information is not shown for datpath interfaces (fp-eth0 to fp-eth3) on a Bare metal edge hardware with Intel 810 XXV Nics enabled with Enhanced data path 

However LLDP information is displayed for management interfaces (eth0 and eth1) configured with same Intel Nics.

Environment

4.2.2.1

Cause

When the physical port is bound to the datapath (e.g. fp-eth0), LLDP packets were not received. The driver already adds a switch rule to forward LLDP to the default VSI, but on some adapters (e.g. E810) the
firmware can redirect LLDP before it reaches the switch, so the rule never applies.

Resolution

This issue is fixed with NSX release 4.2.4 and NSX 9.0 releases. Upgrade bare metal NSX Edge nodes to 4.2.4 to resolve the issue 

Note : This fix is exclusively for the "net_ice" driver and does not apply to any other NIC.
