Data Center Technology Commands 1156
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).
