Learn how to set up VMkernel adapters to provide network connectivity to hosts and to accommodate system traffic of vMotion, IP storage, Fault Tolerance logging, vSAN , and so on.
What to read next
VMkernel Networking Layer The VMkernel networking layer provides connectivity to hosts and handles the standard system traffic of vSphere vMotion, IP storage, Fault Tolerance, vSAN , and others. You can also create VMkernel adapters on the source and target vSphere Replication hosts to isolate the replication data traffic.
Create a VMkernel Adapter on a vSphere Standard Switch Learn how to create a VMkernel network adapter on a vSphere standard switch to provide network connectivity for hosts and to handle the system traffic for vSphere vMotion, IP storage, Fault Tolerance logging, vSAN , and so on. You can also create VMkernel adapters on the source and target vSphere Replication hosts to isolate the replication data traffic. Dedicate a VMkernel adapter to only one traffic type.
Create a VMkernel Adapter on a Host Associated with a vSphere Distributed Switch Learn how to create 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, vSAN , and others. You can set up VMkernel adapters for the standard system traffic on vSphere standard switches and on vSphere distributed switches.
Edit a VMkernel Adapter Configuration Learn how to modify the supported traffic type for a VMkernel adapter, or the way IPv4 or IPv6 addresses are obtained.
Override the Default Gateway of a VMkernel Adapter Learn how to override the default gateway for a VMkernel adapter to provide a different gateway for vSphere vMotion.
Configure the VMkernel Adapter Gateway by Using esxcli Commands Learn how to override the default gateway of a VMkernel adapter to provide a different gateway for vSphere vMotion by using esxcli commands.
Configure the resolv.conf File by Using esxcli Commands The resolv.conf
file is used to configure centrally managed DNS servers. You can configure entries in the /etc/resolv.conf
file using esxcli commands, which allows the modification to remain when rebooting the ESXi host. The property can be set explicitly if DHCP is not enabled.
Configure the DNS Hosts File by Using ESXCLI Commands The DNS hosts file is used for mapping hostnames or domain names to IP addresses. You can configure entries in the /etc/hosts
file using esxcli commands, which allows the modifications to remain unchanged while rebooting the ESXi host.
View TCP/IP Stack Configuration on a Host You 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 Learn how to modify the DNS and default gateway configuration of a TCP/IP stack on a host. You can also change the congestion control algorithm, the maximum number of connections, and the name of custom TCP/IP stacks.
Create a Custom TCP/IP Stack Learn how to create a custom TCP/IP stack on a host to forward networking traffic through a custom application.
Remove a VMkernel Adapter Learn how to remove 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.
