Priority Flow Control Commands

Use the priority-flow-control priority command in Datacenter-Bridging 

Config mode to enable the priority group for lossless (no-drop) or lossy (drop) 

behavior on the selected interface. Up to two lossless priorities can be enabled 

on an interface. 
Use the no form of the command to return all priorities to their default lossy 

behavior. 

no priority-flow-control priority

The default behavior for all priorities is drop.

Datacenter-Bridging Config mode

The administrator must configure the same no-drop priorities across the 

network in order to ensure end-to-end lossless behavior. Ports that are 

configured to use the DCBX auto-configuration roles (auto-up or auto-down) 

have their PFC settings overridden. Only ports configured as DCBX manual 

role utilize the configured PFC settings.

The following example sets priority 3 to no drop behavior.

s1(config)#interface te1/0/1

drop

Disable lossless behavior on the selected priorities.

no-drop

Enable lossless behavior on the selected priorities.
