#VCP #Network #WIP #Concept ## vSphere Standard Switch Standard switch is available in all licensing models. Is created on each ESXi host, no vCenter needed. [[vSphere - VMkernel Ports.md]] can be configured directly on a per host basis. [[../../../Concepts/IT/vSphere - Networking concepts.md#Port Group]] can be configured only on Standard switches, [[../../../Concepts/IT/vSphere - Networking concepts.md#Distributed Port Groups]] are only available on [[vSphere - Distributed Switch.md]] ![[_media/vSphere - Standard Switch2024-07-19.png|600]] ### NIC teaming There are different types of Teaming policies on a Standard switch. #### NIC Teaming by originating Port ID Every virtual machine is assigned a Port ID, all traffic on that Port ID is forwarded automatically to a physical adapter. eg. - VM1 (PortID 1) -> vmnic1 - VM2 (PortID 2) -> vmnic2 - VM3 (PortID 3) -> vmnic1 - [...] It is important to keep in mind that with this type of NIC teaming, that no Channel (Etherchannel/Port channel) is configured on the physical environment. #### NIC Teaming by Source MAC hash Almost the same as NIC Teaming by originating Port ID, but it uses MAC Adresses instead of Port IDs #### NIC Teaming by IP Hash Hash of Source and Destination is created, based on that hash the traffic is distributed to the different vmnics. Traffic from the same VM to different sources can be sent through different vmnics eg.: - VM1 192.168.10.10 -> 192.168.20.1 (vmnic1) - VM1 192.168.10.10 -> 192.168.50.1 (vmnic2) For this method Port channel/Ether channel should be used, because of different Interfaces being used for the packets. ## Maximums - 1016 active/ephemeral ports
