vSphere Standard Switch
A software-based switch that resides in the VMkernel and provides traffic management for VMs. Managed independently on each ESXi host.
vSphere Distributed Switch
A software-based switch that resides in the VMkernel and provides traffic management for VMs and the VMkernel. Shared by and managed across ESXi hosts and clusters within a vSphere datacenter.
Port/Port Group
A logical object on a vSwitch that provides specialized services for the VMkernel or VMs.
VMkernel Port
A specialized virtual switch port type that is configured with an IP address to allow hypervisor traffic, vMotion, iSCSI storage access, VMware Virtual SAN traffic, NAS or NFS access, and Fault Tolerance (FT) logging. VMkernel ports are also created for VXLAN tunneling endpoints (VTEPs) as used by the VMware NSX network virtualization and security platform. A VMkernel port is also called a vmknic.
VM Port Group
A group of virtual switch ports that share a common configuration and allow VMs that are configured on the same port group or accessible PVLAN or on the physical network.
Virtual LAN
A logical LAN configured on a virtual or physical switch that provides efficient traffic segmentation, broadcast control, security, and effective bandwidth utilization by providing traffic only to the ports configured for that VLAN.
Trunk Port
A port on a physical switch that listens for and knows how to pass traffic for multiple VLANs. It does so by maintaining the 802.1q VLAN tagging for traffic moving through the trunk port to the connected device(s). Trunk ports are typically used for switch-to-switch connections to allow VLANs to pass freely between switches.
Access Port
A port on a physical switch that passes traffic for only a single VLAN. Unlike a trunk port which maintains the VLAN identification for traffic moving through the port, an access port strips away the VLAN information for traffic moving through the port.
NIC Teaming
The aggregation of physical network interface cards (NICs) to form a single logical communication channel.
VMXNET Adapter
A virtualized network adapter operating inside a guest operating system (guest OS). The VMXNET adapter is a high performance, 1 Gbps virtual network adapter that operates only if VMware Tools has been installed.
Vlance Adapter
A virtualized network adapter operating inside a guest OS. The Vlance adapter is a 10/100 Mbps network adapter that is widely compatible with a range of operating systems. It is the default adapter used until the VMware Tools installation is completed.
e1000 Adapter
A virtualized network adapter that emulates the Intel e1000 network adapter. The Intel e1000 is a 1 Gbps network adapter. Most common in 64-bit VMs.
