show lldp dcbx

Displays the DCBX configuration and PFC or ETS TLV status on an interface.

Syntax
show lldp dcbx {detail | ets detail | pfc detail | interface ethernet node/slot/port[:subport] [ets detail | pfc detail]
Parameters
  • detail — Display DCBX configuration information of all the interfaces in detail.
  • interface ethernet node/slot/port[:subport] — Enter interface information.
  • ets detail — Display the ETS TLV status and operation with DCBX peers.
  • pfc detail — Display the PFC TLV status and operation with DCBX peers.
Default
Not configured
Command Mode
EXEC
Usage Information

Enable DCBX before using this command. DCBX advertises all TLVs — PFC, ETS Recommendation, ETS Configuration, DCBXP, and basic TLVs by default.

NOTE In the command output, the Is configuration source parameter always displays False. Configuration source is the type of port role that is not supported.
