When you connect to an ESXi host using the VMware Host Client, you can view and configure vSphere standard switches, port groups, physical NICs, VMkernel NICs, and TCP/IP stacks. What to read next Managing Port Groups in the VMware Host ClientYou can manage port group settings to configure traffic management, enhance networking security, and enhance performance." By using the VMware Host Client, you can add and remove port groups, examine port group information, and edit port group settings, such as NIC teaming and traffic shaping. Managing Virtual Switches in the VMware Host ClientIn the VMware Host Client, you can configure various virtual switch settings, such as link discovery, NIC teaming, and traffic shaping. Managing Physical Network Adapters in the VMware Host ClientAssign a physical adapter to a standard switch to provide connectivity to virtual machines and VMkernel adapters on the host that you are managing. Managing VMkernel Network Adapters in the VMware Host ClientIn the VMware Host Client, you can add and remove VMkernel network adapters (NICs), as well as view and modify the VMkernel NIC settings. View TCP/IP Stack Configuration on a Host in the VMware Host ClientYou can view the DNS and routing configuration of a TCP/IP stack on a host. You can also view 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 VMware Host ClientYou can change the DNS and default gateway configuration of a TCP/IP stack on a host.
