NIC Driver Configuration
Notes:
TOE is supported and enabled by default.
TOE is not supported on LPe16202 CFAs and OCe14000-series adapters.
Configuring NIC Driver Options
The Windows Server NIC driver supports configurable driver options through the
Advanced Property page in Windows Device Manager. For information on how to
configure the options through the Advanced Property page, see “Modifying Advanced
Properties” on page 607.
For more information on NIC driver options, see “Network Driver Performance
Tuning” on page 652.
You can also set configurable driver options using Microsoft PowerShell on Windows
Server 2012. Refer to the documentation that accompanies the Windows Server 2012
operating system for more information on using PowerShell.
See Table 3-3 on page 592 for a list of NIC driver options.
Advisory: PowerShell Behavior
Issues with Capabilities Reported by Standard PowerShell Commands
(Get-NetAdapter)
Driver parameter default registry values are initially populated from the driver
installation INF file. Thereafter, the registry is written to only if the default settings are
explicitly overridden. PowerShell uses these registry values to report capabilities with
the result that the registry values may not always reflect what is supported in the
current configuration.
The default settings can be modified through the Driver Properties page, standard
PowerShell commands, and utilities like occfg (for more information on occfg, see
“Using OCCFG for Windows NIC Driver Options” on page 613).
Standard PowerShell (Get-NetAdapter*) commands behave in the following manner:
If the feature is currently enabled, the driver reports its current capabilities.
PowerShell reports all of the feature capabilities based on what the driver
indicates. These are guaranteed to be what the NIC supports in the current
configuration.
If the feature is not enabled, the driver does not report any current capabilities.
At that point, PowerShell searches the registry for keys related to the feature
and reports their values. These are either the default values (INF) or the last
configured user values (if overwritten by the user). Default values are only
intended as maximum upper bounds; they are not guaranteed resources
supported in every configuration.
