The Data Center Bridging Exchange Protocol (DCBx) is used by DCB 

devices to exchange configuration information with directly connected peers. 

The protocol is also used to detect misconfiguration of the peer DCB devices 

and, optionally, for configuration of peer DCB devices. For information about 

configuring DCBx settings, see "Configuring Data Center Bridging Features" 

on page 983. DCBx is a link-local protocol and operates only on individual 

links.

Enhanced Transmission Selection (ETS) allows the switch to allocate 

bandwidth to traffic classes and share unused bandwidth with lower-priority 

traffic classes while coexisting with strict-priority traffic classes. ETS is 

supported on the Dell Networking N4000 series switches and can be 

configured manually or automatically using the auto configuration feature. 

For more information about ETS, see "Enhanced Transmission Selection" on
