Field Description
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 Version 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 DCBx protocol: ACK
or IN-SYNC.
Peer DCBx Status: DCBx Operational Version DCBx version advertised in Control TLVs received
from peer device.
Peer DCBx Status: DCBx Max Version Supported Highest DCBx version supported in Control TLVs
received from peer device.
Peer DCBx Status: Sequence Number Sequence number transmitted in Control TLVs
received from peer device.
Peer DCBx Status: Acknowledgment Number Acknowledgement number transmitted in Control
TLVs received from peer device.
Total DCBx Frames transmitted Number of DCBx frames sent from local port.
Total DCBx Frames received Number of DCBx frames received from remote
peer port.
Total DCBx Frame errors Number of DCBx frames with errors received.
Total DCBx Frames unrecognized Number of unrecognizable DCBx frames received.
QoS dot1p Traffic Classification and Queue Assignment
The following section describes QoS dot1P traffic classification and assignments.
DCB supports PFC, ETS, and DCBx to handle converged Ethernet traffic that is assigned to an egress
queue according to the following QoS methods:
Honor dot1p You can honor dot1p priorities in ingress traffic at the port or global switch level
(refer to Default dot1p to Queue Mapping) using the service-class dynamic
dot1p command in INTERFACE configuration mode.
Layer 2 class maps You can use dot1p priorities to classify traffic in a class map and apply a service
policy to an ingress port to map traffic to egress queues.
