Verifying DCB and LLDP Configurations
Determine Whether Interfaces Are Active
Determine Whether LLDP is Running and Recognizing Peers
Disable DCB for Each Interface
Enable and Disable a Specific DCB Feature
Configure the Mode for the DCB Feature
Display DCBX Feature Statistics and Control Information
Display Output of Unstarted DCBX Protocol Exchange
Display Output of DCBX TLV Exchange
The following example shows the default configuration values for all three DCB features. Perform the following task to apply the default DCB configuration, enabling all three of the DCB features.
See Default Settings for detailed information about the specifications used in the following example. See other sections in this document for additional details on each command.
