Products

Issue/Introduction

Symptoms:
NIC will be unstable with firmware 20.0.17
NIC will be completely down with firmware 20.5.13

Environment

VMware NSX-T Data Center 3.x
VMware NSX-T Data Center

Cause

DPDK firmware support matrix for X710/XL710/XXV710 has
18.05 6.01
19.11 7.0

NSX 3.1 uses DPDK 18.05, but some driver updates have been backported, so 7.1 does work.

NSX 3.2 will use DPDK 19.11.

Resolution

Customers running Bare Metal Edges in NSX-T 3.1 should not upgrade Intel XXV710 firmware above 19.5.12 (driver 7.1) 

Newer firmware will work with later versions of NSX-T.

Workaround:
Downgrade firmware to 19.5.12
