Synopsis

show qos flowcontrol interface [tengigabitethernet rbridge-id/slot/port |
gigabitethernet rbridge-id/slot/port | all]

Operands

tengigabitethernet rbridge-id/slot/port

Specifies a valid 10-gigabit Ethernet interface.

rbridge-id

Specifies the RBridge ID.

slot

Specifies a valid slot number.

port

Specifies a valid port number.

gigabitethernet rbridge-id/slot/port

Specifies a valid 1-gigabit Ethernet interface.

rbridge-id

Specifies the RBridge ID.

slot

Specifies a valid slot number.

port

all

Reports QoS flow control statistics for all interfaces within the system.

Defaults

None

Command Modes

Privileged EXEC mode

Description

Use this command to display the runtime state retrieved from the dataplane reflecting the
operation of 802.3x pause or Priority Flow Control (PFC) on an interface.

Usage Guidelines

The administrative state for pause generation and reception or processing is presented for the
interface (802.3x mode) or for each CoS (PFC mode). TX_Pause frame generation statistics are
always presented for the interface. The RX_Pause BitTimes is presented for the interface
(802.3x mode) or for each CoS (PFC mode). When PFC is deployed under the CEE Provisioning
model, then the command reports whether the Data Center Bridging eXchange protocol (DCBX)
has overridden the user configuration, for example when the DCBX detects a mis-configuration
between CEE peers, it disables PFC operationally.

The gigabitethernet rbridge-id/slot/port parameter is used only on Brocade VDX 6710,
Brocade VDX 8770-4, and Brocade VDX 8770-8 switches.
