User Guidelines
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.
Examples
This example configures an FCF facing port:
console(config-if-Te1/1/1)#lldp dcbx port-role auto-up
This example configures an FCoE host facing port:
console(config-if-Te1/1/1)#lldp dcbx port-role auto-down
show lldp tlv-select
Use the show lldp tlv-select command in Privileged EXEC mode to display
the per interface TLV configuration.
Syntax
show lldp tlv-select [interface <all | interface-id>]
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.
