Data Center Bridging Commands

configuration ports. Ports receiving auto-configuration information from the 

configuration source ignore their current settings and utilize the 

configuration source information.
When a configuration source is selected, local ETS and PFC configuration 

for all auto-up, auto-down and config-source ports is overridden by the 

configuration received from the configuration source.
In order to reduce flapping of configuration information, if the configuration 

source port is disabled, disconnected or loses LLDP connectivity, the system 

clears the selection of configuration source port (if not manually selected) 

and enables the willing bit on all auto-upstream ports. The configuration on 

the auto-configuration ports is not cleared (configuration holdover).  If the 

user wishes to clear the configuration on the system in this scenario, the user 

can put the configuration source port into manual mode.
When a new port is selected as configuration source, it is marked as the 

configuration source, the DCBX configuration is refreshed on all auto-

configuration ports and each port may begin configuration negotiation with 

their peer again (if any information has changed).

This chapter explains the following commands:
