Version Description
9.3 (0.1) Introduced on S6000, S4810, and S4820T.
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
• “dcb-map” CLI on interface is mutually exclusive to “no dcb ets enable” and
“no dcb pfc enable”.
• “pfc priority” CLI is mutually exclusive to “no dcb pfc enable” command.
