After you have configured NPAR mode, you can modify the minimum and
maximum bandwidth per NPAR. The changes take effect immediately; no reboot
is required. The minimum and maximum bandwidths are specified as percentages
of the link bandwidth, where:

Minimum bandwidth is the minimum guaranteed bandwidth to a partition.
Maximum bandwidth is the maximum value that a partition is permitted to use.
NPAR mode supports iSCSI boot, FCoE boot, and PXE boot in their respective
partitions.

Using NPAR under ESX
VMware vSphere provides a CIM monitoring framework for both classic ESX and
ESXi. Use this framework to configure and manage Ethernet interfaces. On an
ESX Server, you can configure and manage Ethernet interfaces using a command
line interface. On an ESXi Server, use the remote command line interfaces
(remote CLIs).

(remote CLIs).
All NPAR Ethernet functions are enumerated by the hypervisor, controlled by the
driver running in the hypervisor, and configured similar to other Ethernet
interfaces. For more details, see

You would typically create a virtual switch (vSwitch) for each NPAR interface. You
can configure virtual machines (VMs) to use the standard virtual network devices,
such as VMXNET 3 adapters. On each interface, you can configure features such
as NetQueue. Although it is possible to configure all standard aggregation and
failover configurations supported by ESX using NPAR interfaces as uplinks, it is
not useful to have multiple uplinks with NPARs belonging to the same physical
port.

The vSwitch switches the packets when VMs are assigned to share the same
NPAR. The embedded switch (eSwitch) on the adapter switches packets when
packets are sent by a VM on an NPAR destined to another VM that is connected
to a vSwitch on a different NPAR belonging to the same physical port. If the two
NPARs are associated with different physical ports, the external switch forwards
packets between them.

Perform vSwitch configuration using either standard service console commands
or RCLI commands. For specific command options, refer to the VMware
