show interface pfc

Displays the PFC configuration applied to ingress traffic on an interface, including priorities and link delay.

Syntax show interface port-type slot/port pfc {summary | detail}
Parameters
port-type slot/ port pfc Enter the port-type slot and port PFC information.
{summary | detail} Enter the keyword summary for a summary list of results or enter the keyword detail for a full list of results.
  • NOTE: This command also enables you to view information corresponding to a range of ports.
    • 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 .

Supported Modes All Modes
Command History
Version Description
9.9(0.0) Introduced on the FN IOM and added support to display the interface configurations corresponding to a range of ports.
9.4(0.0) Supported on the FN I/O Aggregator.
9.2(0.0) Introduced on the M I/O Aggregator.

Usage Information

To clear the PFC TLV counters, use the clear pfc counters interface port-type slot/port command.

The following describes the show interface pfc summary command shown in the following example.

Field Description
Interface Interface type with stack-unit and port number.
Admin mode is on Admin is enabled PFC admin mode is on or off with a list of the configured PFC priorities. When the PFC admin mode is on, PFC advertisements are enabled to be sent and received from peers; received PFC configuration take effect. The admin operational status for a DCBX exchange of PFC configuration is enabled or disabled.
Remote is enabled, Priority list Remote Willing Status is enabled Operational status (enabled or disabled) of peer device for DCBX exchange of PFC configuration with a list of the configured PFC priorities. Willing status of peer device for DCBX exchange (Willing bit received in PFC TLV): enabled or disable.
Local is enabled DCBX operational status (enabled or disabled) with a list of the configured PFC priorities.
Operational status (local port) Port state for current operational PFC configuration:
  • Init: Local PFC configuration parameters were exchanged with the peer.
  • Recommend: Remote PFC configuration parameters were received from the peer.
  • Internally propagated: PFC configuration parameters were received from the configuration source.
PFC DCBX Oper status Operational status for the exchange of the PFC configuration on the local port: match (up) or mismatch (down).
Reason Reason displayed when the DCBx operational status for PFC on a port is down.
State Machine Type Type of state machine used for DCBX exchanges of the PFC parameters: Feature — for legacy DCBX versions; Symmetric — for an IEEE version.
TLV Tx Status Status of the PFC TLV advertisements: enabled or disabled.
PFC Link Delay Link delay (in quanta) used to pause specified priority traffic.
Application Priority TLV: FCOE TLV Tx Status Status of FCoE advertisements in application priority TLVs from the local DCBX port: enabled or disabled.
Application Priority TLV: SCSI TLV Tx Status Status of ISCSI advertisements in application priority TLVs from the local DCBX port: enabled or disabled.
Application Priority TLV: Local FCOE Priority Map Priority bitmap the local DCBX port uses in FCoE advertisements in application priority TLVs.
Application Priority TLV: Local ISCSI Priority Map Priority bitmap the local DCBX port uses in ISCSI advertisements in application priority TLVs.
Application Priority TLV: Remote FCOE Priority Map Status of FCoE advertisements in application priority TLVs from the remote peer port: enabled or disabled.
Application Priority TLV: Remote ISCSI Priority Map Status of iSCSI advertisements in application priority TLVs from the remote peer port: enabled or disabled.
PFC TLV Statistics: Input TLV pkts Number of PFC TLVs received.
PFC TLV Statistics: Output TLV pkts Number of PFC TLVs transmitted.
PFC TLV Statistics: Error pkts Number of PFC error packets received.
PFC TLV Statistics: Pause Tx pkts Number of PFC pause frames transmitted.
PFC TLV Statistics: Pause Rx pkts Number of PFC pause frames received.
