NOTE: To disable TLV transmission, use the no form of the command; for example, no advertise DCBx-appln-
tlv.
6 Congure the FCoE priority advertised for the FCoE protocol in Application Priority TLVs.
PROTOCOL LLDP mode
[no] fcoe priority-bits priority-bitmap
The priority-bitmap range is from 1 to FF.
The default is 0x8.
DCBx Error Messages
The following syslog messages appear when an error in DCBx operation occurs.
LLDP_MULTIPLE_PEER_DETECTED: DCBx is operationally disabled after detecting more than one DCBx
peer on the port interface.
LLDP_PEER_AGE_OUT: DCBx is disabled as a result of LLDP timing out on a DCBx peer interface.
DSM_DCBx_PEER_VERSION_CONFLICT: A local port expected to receive the IEEE or CEE version
in a DCBx TLV from a remote peer but received a different, conflicting DCBx version.
DSM_DCBx_PFC_PARAMETERS_MATCH and DSM_DCBx_PFC_PARAMETERS_MISMATCH: A local DCBx port received
a compatible (match) or incompatible (mismatch) PFC configuration from a peer.
DSM_DCBx_ETS_PARAMETERS_MATCH and DSM_DCBx_ETS_PARAMETERS_MISMATCH: A local DCBx port received

Debugging DCBx on an Interface
To enable DCBx debug traces for all or a specic control paths, use the following command.
• Enable DCBx debugging.
EXEC PRIVILEGE mode
debug DCBx {all | auto-detect-timer | config-exchng | fail | mgmt | resource | sem | tlv}
• all: enables all DCBx debugging operations.
• auto-detect-timer: enables traces for DCBx auto-detect timers.
• config-exchng: enables traces for DCBx conguration exchanges.
• fail: enables traces for DCBx failures.
• mgmt: enables traces for DCBx management frames.
• resource: enables traces for DCBx system resource frames.
• sem: enables traces for the DCBx state machine.
• tlv: enables traces for DCBx TLVs.
