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

Use the following to set the willing bit to True or False. 1 for enabled, 0 for disabled.

C:\> New-NetQosTrafficClass -name "SMB class" -priority 4 -bandwidthPercentage 30 -Algorithm ETS
Note: By default, all 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

(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.
