(often VLAN 1) for any regular data traffic. It is a common best practice to avoid using native VLAN VLAN 1 or 100, it could be any number depending on your However, in many enterprise networks, the native VLAN is VLAN 1 is the default native VLAN ID for most Cisco switches. Implicitly treat all untagged frames as the native VLAN frame. In many types of switches, and in which case the trunk ports Native VLAN frames are not tagged with VLAN IDs Native VLAN is used for switch control and management Ensure that the native VLAN for an 802.1Q trunk is the same on both ends of the trunk link.ģ) Native VLAN Issue (a.k.a. The native VLAN should also be distinct from all user VLANs. The following table shows the options that the MX Platform provides for NIC teaming: Table 13.

A recommended security practice is to change the native VLAN to a different VLAN than VLAN 1. Note: If using VMware ESXi and LACP, it is recommended to use VMware ESXi 6.7.0 Update 2 or later. Therefore, when the native VLAN is changed to something other than VLAN 1, all control traffic is tagged on IEEE 802.1Q VLAN trunks (tagged with VLAN ID 1).

MAC addresses of all vNICs in VMs - are there any duplicate or manually assigned MAC addresses? VMware vSphere 6.7 VMware ESXi 6.7 vCenter Server 6.7.Asymmetric routing can cause unicast flooding.Do you isolate your VMkernel's vMotion (known to cause unicast flooding otherwise), management, VM and IP storage traffic physically or using VLANs?.Check your physical NICs on the hosts for some weird and unsupported vendor teaming configs.

Are you using Microsoft Network Load Balancing within vSphere at all? It's known to cause unicast flooding.

If your switch doesn't have the frame's destination MAC in its CAM table, it would simply flood the frame out off all but the ingress port regardless of whether the frame is unicast or not. A unicast frame always has a source and a destinatination MAC addresses. Click the NIC Teaming tab, set Notify Switches to No. Your pNIC team (or a single adapter) acts as a simple bridge for any vSwitch it's assigned to so it passes VM traffic through. As a result, an administrator must add a static ARP entry in the router, mapping the cluster IP.

Let's look at L2 where VMKernel unicast traffic flows.
