Lldp Dcbx Port-Role - NETGEAR M6100 Series Reference Manual

lldp dcbx port-role

Use the lldp dcbx port-role command in Interface Configuration mode to configure the
port role to manual, auto-upstream, auto-downstream and configuration source. In order to
reduce configuration flapping, ports that obtain configuration information from a configuration
source port will maintain that configuration for 2x the LLDP timeout, even if the configuration
source port becomes operationally disabled.
Default The default port role is manual.

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 In this role, the port has been manually selected to be the configuration source. Configuration
Source received over this port 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.
