Dell Command Line Reference Guide for the S4048–ON System 9.14.2.5

PDF

show interface dcbx detail

Displays the DCBX configuration on an interface.

Syntax
show interface port-type dcbx detail
Parameters
port-type
Enter the port type along with the port number.
NOTE: This command also enables you to view information corresponding to a range of ports. However, for Open Networking (ON) platforms the notation for specifying port range in the command is different from how you specify in non-ON platforms.
  • For non-ON platforms, you can specify multiple ports as slot/port-range. For example, if you want to display information corresponding to all ports between 1 and 4, specify the port range as show interfaces interface-type 1/1 - 4.
  • For ON platforms, you can specify multiple ports as slot/port/[subport] - slot/port/[subport]. For example, if you want to display information corresponding to all ports between 1 and 4, specify the port range as show interfaces interface-type 1/1/1 - 1/1/4.

Usage Information

To clear DCBX frame counters, use the clear dcbx counters interface stack-unit/port command.

The following describes the show interface dcbx detail command shown in the following example.

Field
Description
Interface
Interface type with chassis slot and port number.
Port-Role
Configured the DCBX port role: auto-upstream, auto-downstream, config-source, or manual.
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 receive 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 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 the DCBX protocol: ACK or IN-SYNC.
Peer DCBX Status: DCBX Operational Version
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.
Total DCBX Frames unrecognized
Number of unrecognizable DCBX frames received.
