auto-upstream | manual} command.
Parameters

manual
Enter the DCBX port role, where:
config-source: congures the port to serve as the conguration source on the
switch.
auto-upstream: congures the port to receive a peer conguration. The
conguration source is elected from auto-upstream ports.
auto-downstream: congures the port to accept the internally propagated DCB
conguration from a conguration source.
manual: congures the port to operate only on administer-congured DCB
parameters. The port does not accept a DCB conguration received form a peer or a
local conguration source.
