Field Description
DCBx Operational Status Operational status (enabled or disabled) used to elect a
conguration source and internally propagate a DCB
conguration. The DCBx operational status is the combination of
PFC and ETS operational status.
Conguration Source Species whether the port serves as the DCBx conguration
source on the switch: true (yes) or false (no).
Local DCBx Compatibility mode DCBx version accepted in a DCB conguration as compatible. In
auto-upstream mode, a port can only received a DCBx version
supported on the remote peer.
Local DCBx Congured mode DCBx version congured on the port: CEE, CIN, IEEE v2.5, or
Auto (port auto-congures 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.
PFC and ETS Conguration Examples
This section contains examples of how to congure and apply DCB input and output policies on an interface.
Using PFC and ETS to Manage Data Center Trac
The following shows examples of using PFC and ETS to manage your data center trac.
In the following example:
• Incoming SAN trac is congured for priority-based ow control.
• Outbound LAN, IPC, and SAN trac is mapped into three ETS priority groups and congured for enhanced trac selection
(bandwidth allocation and scheduling).
