Syntax
lldp dcbx port-role {auto-up |auto-down | manual | configuration-source}
• Manual—Ports operating in the ‘Manual’ role do not have their
configuration affected by peer devices or by internal propagation of
configuration. These ports will advertise their configuration to their peer if
DCBX is enabled on that port. The willing bit is set to disabled on manual
role ports.
• Auto-up—Advertises a configuration, but is also willing to accept a
configuration from the link-partner and propagate it internally to the auto-
downstream ports as well as receive configuration propagated internally by
other auto-upstream ports. These ports have the willing bit enabled. These
ports should be connected to FCFs.
• Auto-down—Advertises a configuration but is not willing to accept one
from the link partner. However, the port will accept a configuration
propagated internally by the configuration source. These ports have the
willing bit set to disabled. Selection of a port based upon compatibility of
the received configuration is suppressed. These ports should be connected
to a trusted FCF.
• Configuration Source—In this role, the port has been manually selected
to be the configuration source. Configuration received over this port is
used to configure the switch and is propagated to the other auto-
configuration ports. Selection of a port based upon compatibility of the
received configuration is suppressed. These ports should be connected to a
trusted FCF. These ports have the willing bit enabled.
