Usage
Information
By default, PFC is enabled on S5000 Ethernet ports and 802.1p priorities are included in DCBx
negotiation with peer PFC devices
Use the no pfc mode on command in a DCB map and apply the map to an interface to
disable PFC before you configure lossless queues on a port on which PFC is not required. To
configure lossless queues, use the pfc no-drop queues command
To re-enable PFC operation on an interface, open the DCB map for editing (dcb-map
command), enter the pfc mode on command, and re-apply the map on the interface.
You cannot enable PFC and link-level flow control at the same time on an interface.
