Parameter Description
Default Configuration
The default port role is manual.
Command Mode
Interface Config
Parameter Description
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.
