Patch a Host Transport Node

Transport nodes are hypervisor hosts that will participate
in an NSX-T overlay. For a hypervisor host, this means that it hosts
VMs that will communicate over NSX-T logical switches.

This API creates transport node for a host node (hypervisor) in the transport network.

When you run this command for a host, NSX Manager attempts to install the
NSX kernel modules, which are packaged as VIB, RPM, or DEB files. For the
installation to succeed, you must provide the host login credentials and the
host thumbprint.

To get the ESXi host thumbprint, SSH to the host and run the
openssl x509 -in /etc/vmware/ssl/rui.crt -fingerprint -sha256 -noout
command.

To generate host key thumbprint using SHA-256 algorithm please follow the
steps below.

Log into the host, making sure that the connection is not vulnerable to a
man in the middle attack. Check whether a public key already exists.
Host public key is generally located at '/etc/ssh/ssh_host_rsa_key.pub'.
If the key is not present then generate a new key by running the following
command and follow the instructions.

ssh-keygen -t rsa

Now generate a SHA256 hash of the key using the following command. Please
make sure to pass the appropriate file name if the public key is stored with
a different file name other than the default 'id_rsa.pub'.

awk '{print $2}' id_rsa.pub | base64 -d | sha256sum -b | sed 's/ .*$//' | xxd -r -p | base64

Additional documentation on creating a transport node can be found
in the NSX-T Installation Guide.

In order for the transport node to forward packets,
the host_switch_spec property must be specified.

Host switches (called bridges in OVS on KVM hypervisors) are the
individual switches within the host virtual switch. Virtual machines
are connected to the host switches.

When creating a transport node, you need to specify if the host switches
are already manually preconfigured on the node, or if NSX should create
and manage the host switches. You specify this choice by the type
of host switches you pass in the host_switch_spec property of the
TransportNode request payload.

For a KVM host, you can preconfigure the host switch, or you can have
NSX Manager perform the configuration. For an ESXi host NSX Manager always
configures the host switch.

To preconfigure the host switches on a KVM host, pass an array
of PreconfiguredHostSwitchSpec objects that describes those host
switches. In the current NSX-T release, only one prefonfigured host
switch can be specified. See the PreconfiguredHostSwitchSpec schema
definition for documentation on the properties that must be provided.
Preconfigured host switches are only supported on KVM hosts, not on
ESXi hosts.

To allow NSX to manage the host switch configuration on KVM hosts,
ESXi hosts, pass an array of StandardHostSwitchSpec objects in the
host_switch_spec property, and NSX will automatically
create host switches with the properties you provide. In the current
NSX-T release, up to 16 host switches can be automatically managed.
See the StandardHostSwitchSpec schema definition for documentation on
the properties that must be provided.

The request should provide node_deployement_info.
This API is available when using VMware Cloud (AWS, Dell-EMC, Outpost, Hyperscalers) or VMware NSX-T.

(Deprecated)

Name	Description	Type	Notes
esx_mgmt_if_migration_dest	The network ids to which the ESX vmk interfaces will be migrated A comma separated list of network ids. When migrating vmks into logical switches, the ids are the logical switches's ids. When migrating out of logical switches, the ids are vSphere Standard Switch portgroup names in a single vSphere Standard Switch, or distributed virtual portgroup names in a single distributed virtual switch (DVS). This property can only used together with 'if_id'.	string
if_id	The ESX vmk interfaces to migrate A comma separated list of vmk interfaces (for example, vmk0,vmk1). This property can only used along with 'esx_mgmt_if_migration_dest'. If all vmk interfaces will be migrated into the same logical switch or DV portgroup, the 'esx_mgmt_if_migration_dest' can be just one logical switch id or DV portgroup name. Otherwise the number of vmks in this list must equal the number of ids in 'esx_mgmt_if_migration_dest' list, and the orders of the two lists are important because the vmks match the network ids one by one in the same order.	string
ping_ip	IP Addresses to ping right after ESX vmk interfaces were migrated. A comma separated list of IP addresses that match the vmk interfaces given in property 'if_id" or 'vnic' one-by-one in the same order. '0.0.0.0' is a special IP that indicates the pre-migration gateway of the vmk will be pinged post-migration. If a VMK does not need the ping ip or a VM NIC is given inside 'vnic', the ping ip must be skipped but the comma has to stay. For example, '0.0.0.0,,10.1.1.1' indicates the vmk or VM NIC at the 2nd position does not need ping post-migration. Right after all ESX vmk interfaces are migrated, ping packets will be sent through each vmk to its given ping_ip to check if the migraton will break the network connectivity or not. If any vmk_ping fails, the whole migration of all vmks will be rolled back and transport-node will be in failed state.	string
skip_validation	Whether to skip front-end validation for vmk/vnic/pnic migration If this property is set true, all front-end validation for vmk, vnic, and/or pnic migration will be skipped. This is useful when the remote host becomes unreachable as a result of a migration; in which case the front-end validation will always fail because data from the remote host is no longer available. Skipping the validation will allow user to undo the migration by updating the transport node first and then restoring the host network connectivity.	boolean	Default: "False"
vnic	The ESX vmk interfaces and/or VM NIC to migrate A comma separated list of vmk interfaces and/or one VM NIC. Only one VM NIC is allowed in the list; the format must be vmInstanceUuid:DeviceId like '50ca5f2d-1fa2-432d-991e-f01e0e16d182:4000'. An example list is 'vmk0,vmk1,50ca5f2d-1fa2-432d-991e-f01e0e16d182:4000'. The property can only be used along with 'vnic_migration_dest'.	string
vnic_migration_dest	The migration destinations of ESX vmk interfaces and/or VM NIC A comma separated list of vif ids, or port group names. When migrating into logical switches, the ids are vif ids in the logical ports created in the logical switches. When migrating out of logical switches, the ids are vSphere Standard Switch portgroup names in a single vSphere Standard Switch, or distributed virtual portgroup names in a single distributed virtual switch (DVS). The property can only be used in combination with property 'vnic'. The number of vnic interfaces in 'vnic' must equal the number of vif ids or port-group names in this list. The items in the two lists match by the the order.	string
