Table 7-1. DCBx Detail Field Descriptions
Field Description
Interface Interface type with chassis slot and port number.
Port-Role Configured DCBX port role: auto-upstream or auto-downstream.
DCBX Operational Status Operational status (enabled or disabled) used to elect a configuration source and
internally propagate a DCB configuration. The DCBX operational status is the
combination of PFC and ETS operational status.
Configuration Source Specifies whether the port serves as the DCBX configuration source on the switch:
true (yes) or false (no).
Local DCBX
Compatibility mode
DCBX version accepted in a DCB configuration as compatible. In auto-detection
mode, a port can only operate on a DCBX version supported on the remote peer.
Local DCBX Configured
mode
DCBX version configured on the port: CEE, CIN, IEEE v2.5, or Auto (port
auto-configures to use the DCBX version received from a peer).
Peer Operating version DCBX version that the peer uses to exchange DCB parameters.
Local DCBX TLVs
Transmitted
Transmission status (enabled or disabled) of advertised DCB TLVs (see TLV code
at the top of the show command output).
Local DCBX Status:
DCBX Operational
Ve rsi on
DCBX version advertised in Control TLVs.
Local DCBX Status:
DCBX Max Version
Supported
Highest DCBX version supported in Control TLVs.
Local DCBX Status:
Sequence Number
Sequence number transmitted in Control TLVs.
Local DCBX Status:
Acknowledgment
Number
Acknowledgement number transmitted in Control TLVs.
Local DCBX Status:
Protocol State
Current operational state of the DCBX protocol: Waiting for ACK or IN-SYNC.
Peer DCBX Status:
DCBX Operational
Ve rsi on
DCBX version advertised in Control TLVs received from the peer device.
Peer DCBX Status:
DCBX Max Version
Supported
Highest DCBX version supported in Control TLVs received from the peer device.
Peer DCBX Status:
Sequence Number
Sequence number transmitted in Control TLVs received from the peer device.
Peer DCBX Status:
Acknowledgment
Number
Acknowledgement number transmitted in Control TLVs received from the peer
device.
Total DCBX Frames
transmitted
Number of DCBX frames sent from the local port.
Total DCBX Frames
received
Number of DCBX frames received from the remote peer port.
Total DCBX Frame errors Number of DCBX frames with errors received.
