There was one hidden NIC that I have just deleted, however believe that was from me removing and re-adding the network adapters. 1 virtual switch, 2 port groups (1 for VMs and 1 for Management Network), 2 uplinks. the new version is 1.7.11, and can be downloaded for 6.0/6.5/6.7. Network operations on this system may be risrupted as a result. If you are using LLDP, please see my Colleagues blog about Intel X710 and LLDP here: Ī new version has been released that fixes some other problems, also including a new MDD problem.
#VMWARE ESXI 6.7 NIC TEAMING ARP DRIVER#
I have not tested the driver at any customer. from the release notes: Fix for MDD event and TX hang caused by TSO_MSS option smaller than 64 bytes Intel/VMware has released a new driver version 1.7.5 that should fixes this issue. There is a known issue with the i40e driver versions up to 2.0.6, so you should use 2.0.7 or newer. I really hopes that Intel will fix this now, the article from the forum is dated May 23th of 2018. The workaround is to uninstall og disable the native driver “i40en” and have a working version or the Linux style driver installed “i40e”. The problem is fixed in ESXi 6.7 that has a new driver version 1.7.1. I40en: i40en_HandleMddEvent:6521: TX driver issue detected, PF reset issued i40en: i40en_HandleMddEvent:6495: Malicious Driver Detection event 0x02 on TX queue 0 PF number 0x00 VF number 0x00 You need to make sure that a gratuitous ARP (GARP) is sent by the failover server and that this GARP is properly processed by all relevant nodes in the segment. The 'IP hash-based routing' is about L2 load balancing - which egress port is used - and has no relevance for IP routing. I the vmkernet.log file you will see, this lines. The ESXis vSwitch doesnt care about IP addresses, just MACs. The is due to a new function in the driver called “Malicious Driver Detection” or MDD for short. I customer using both Dell, HPE and Lenovo servers where I have seee this problem. This is a huge problem. Now, we are going to simplify NIC teaming to the most. If you need a quick refresher, NIC teaming in VMware vSphere is important for both redundancy and load balancing. 775 Chapter 1: Introducing VMware vSphere 6. It is definitely a good idea to have some sort of NIC teaming configuration on your ESXi host. It also enables passive failover in the event of a hardware or network issue. The switch must be set to perform 802.3ad link aggregation in static mode ON and the virtual switch must have its load balancing method. 771 The Bottom Line 772 Appendix A The Bottom Line. NIC teaming in ESXi allows the hypervisor to share traffic among the physical and virtual networks. Link aggregation is never supported on disparate trunked switches. ESXi/ESX host only supports NIC teaming on a single physical switch or stacked switches. We have briefly talked about NIC teaming in VMware vSphere before, and why it is such a powerful tool in our vSphere aresenal. Link Aggregation for VMWare ESXi and ESX. If you are running ESXi 6.0/6.5 and using a Intel X710 network adapter, the network card port may stop forwarding packets, if you are using the native driver (i40en).
