Table 28. show interface DCBx detail Command Description (continued)
Field Description
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-upstream mode, a port can only received a DCBx
version supported on the remote peer.
Local DCBx Configured mode DCBx version configured on the port: CEE, 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.
