Usage
Information
PFC and ETS are enabled by default on the interfaces when DCB is globally enabled
(refer to dcb enable). In some network topology, you may want to disable PFC on
an interface and apply link level flow control; Similarly you may want to disable ETS
on an interface and apply QoS bandwidth configurations.
Limitations

” CLI on interface is mutually exclusive to “
no dcb ets enable
” and

” cannot
coexist at interface level.
• Deprecated CLI “

dcb-policy buffer-threshold (Interface Configuration)
Assign the DCB policy to the DCB buffer threshold profile on interfaces. This setting takes precedence
over the global buffer-threshold setting.

Usage
Information
You can configure a maximum of four lossless (PFC) queues. By configuring four
lossless queues, you can configure four different priorities and assign a particular
priority to each application that your network is used to process. For example, you
can assign a higher priority for time-sensitive applications and a lower priority for
other services, such as file transfers. You can configure the amount of buffer space
