15.3 DCBX Willing Bit
The DCBX willing bit is specified in the DCB specification. If the Willing bit on a device is true, the device is willing to accept
configurations from a remote device through DCBX. If the Willing bit on a device is false, the device rejects any configuration
from a remote device and enforces only the local configurations.
Use the following to set the willing bit to True or False. 1 for enabled, 0 for disabled.
Example
set-netQoSdcbxSetting -Willing 1
Use the following to create a Traffic Class.
C:\> New-NetQosTrafficClass -name "SMB class" -priority 4 -bandwidthPercentage 30 -Algorithm ETS
Note:
By default, all IEEE 802.1p values are mapped to a default traffic class, which has 100% of the bandwidth of the
physical link. The command shown above creates a new traffic class to which any packet tagged with eight IEEE 802.1p
value 4 is mapped, and its Transmission Selection Algorithm (TSA) is ETS and has 30% of the bandwidth. It is possible to
create up to seven new traffic classes. In addition to the default traffic class, there is at most eight traffic classes in the
system.
Use the following in displaying the created Traffic Class:
C:\> Get-NetQoSTrafficClass
Name Algorithm Bandwidth(%) Priority
