in a DCBx TLV from a remote peer but received a different, conflicting DCBxversion.DSM_DCBx_PFC_PARAMETERS_MATCH and DSM_DCBx_PFC_PARAMETERS_MISMATCH: A localDCBx port receiveda compatible (match) or incompatible (mismatch) PFC configuration from a peer.DSM_DCBx_ETS_PARAMETERS_MATCH and DSM_DCBx_ETS_PARAMETERS_MISMATCH: A localDCBx port receiveda compatible (match) or incompatible (mismatch) ETS configuration from a peer.LLDP_UNRECOGNISED_DCBx_TLV_RECEIVED: A local DCBx port received an unrecognizedDCBx TLV froma peer.Debugging DCBx on an InterfaceTo enable DCBx debug traces for all or a specific control paths, use the following command.• Enable DCBx debugging.EXEC PRIVILEGE modedebug 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 configuration 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.Verifying the DCB ConfigurationTo display DCB configurations, use the following show commands.Table 20. Displaying DCB ConfigurationsCommand Outputshow qos dot1p-queue mapping Displays the current 802.1p priority-queuemapping.show dcb [stack-unit unit-number] Displays the data center bridging status, number ofPFC-enabled ports, and number of PFC-enabledqueues. On the master switch in a stack, you canspecify a stack-unit number. The range is from 0 to5.show qos priority-groups Displays the ETS priority groups configured on theswitch, including the 802.1p priority classes and IDof each group.270 Data Center Bridging (DCB)
