Command Purpose

Use this command to enable or disable priority-based flow control function on which priority.

Prerequisites

Command Syntax

priority-flow-control enable priority { 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 }

no priority-flow-control enable priority { 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 }

Command Mode

Interface Configuration

Default

Enable priority-based flow control on priority 3

Usage

Use the priority-flow-control enable priority interface Configuration command to set the interface’s ability to send pause frames to on or off on which priorities.
