You set up VMkernel adapters to provide network connectivity to hosts and to accommodate the traffic of vMotion, IP storage, Fault Tolerance logging, and Virtual SAN. The VMkernel Networking LayerThe VMkernel networking layer provides connectivity to hosts and handles the standard infrastructure traffic of vSphere vMotion, IP storage, Fault Tolerance, and Virtual SAN. You can set up VMkernel adapters for the standard infrastructure traffic on vSphere standard switches and on vSphere distributed switches. View Information About VMkernel Adapters on a Host in the vSphere Web ClientFor each VMkernel adapter, you can view its assigned services, associated switch, port settings, IP settings, TCP/IP stack, VLAN ID, and policies. Create a VMkernel Adapter on a vSphere Standard Switch in the vSphere Web ClientCreate a VMkernel network adapter on a vSphere standard switch to provide network connectivity for hosts and to handle the traffic for vSphere vMotion, IP storage, Fault Tolerance logging, or Virtual SAN. You should dedicate a VMkernel adapter to only one traffic type. Create a VMkernel Adapter on a Host Associated with a vSphere Distributed Switch in the vSphere Web ClientCreate a VMkernel adapter on a host that is associated with a distributed switch to provide network connectivity to the host and to handle the traffic for vSphere vMotion, IP storage, Fault Tolerance logging, and Virtual SAN. You should dedicate a single distributed port group per VMkernel adapter. One VMkernel adapter should handle one traffic type. Edit a VMkernel Adapter Configuration in the vSphere Web ClientYou might need to change the supported traffic type for a VMkernel adapter, or the way IPv4 or IPv6 addresses are obtained. View TCP/IP Stack Configuration on a Host in the vSphere Web ClientYou can view the DNS and routing configuration of a TCP/IP stack on a host, the IPv4 and IPv6 routing tables, the congestion control algorithm, and the maximum number of allowed connections. Change the Configuration of a TCP/IP Stack on a Host in the vSphere Web ClientYou can change the DNS and default gateway configuration of a TCP/IP stack on a host, the congestion control algorithm, the maximum number of connections, and the name of custom TCP/IP stacks. Create a Custom TCP/IP StackYou can create a custom TCP/IP stack on a host to forward VMkernel traffic through a custom application. Remove a VMkernel Adapter in the vSphere Web ClientRemove a VMkernel adapter from a vSphere distributed or a standard switch when you no longer need the adapter. Make sure that you leave at least one VMkernel adapter for management traffic on the host to keep the network connectivity up.
