lldp tlv-select dcbxp
[pfc | application-
priority]

TLVs on this interface. Entering the command with no
parameters enables transmission of all TLVs.
• pfc—Transmit the PFC configuration TLV.
• application-priority—Transmit the application priority
TLV.
lldp dcbx port-role
{auto-up |auto-down |
manual | configuration-
source}
Configure the DCBx port role on the interface:
• 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.
• 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.
• configuration-source—In this role, the port has been
manually selected to be the configuration source.
Configuration 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.
