Usage Guidelines

The no form of this command removes PCP remarking.

In the interface configuration mode, the command enables PCP remarking for each port. The command
can be configured only on Layer 2 ports. The configuration can be done on a physical port, LAG, and
VE port.

Examples

The following example shows how to globally set the PCP bit value to 4:

Device(config)# ip pcp-remark 4

The following example shows how to set the PCP value to 5 on a specific port:

Device(config)# interface ethernet1/1/1

Device(config-if-e1000-1/1/1)# ip pcp-remark 5

Syntax

priority-flow-control priority-group-number

no priority-flow-control priority-group-number

PFC is globally disabled.

Parameters

priority-group-number

Specifies a priority group. The range is 0-3.

Usage Guidelines

The no form of this restores the default flow-control settings.

To enable global PFC, symmetrical-flow-control must be disabled.

You must enable PFC globally before you configure it for priority groups.

Priority flow control and 802.3x flow control are mutually exclusive; therefore, configuring the priority-
flow-control
command disables 802.3x in both transmit and receive directions.

Examples

The following example shows how to enable PFC for a priority group.

Device(config)# priority-flow-control enable

Device(config)# priority-flow-control 2
