Release Information
Statement introduced in Junos OS Release 11.1 for the QFX Series.
Description
Configure a congestion notification profile to enable priority-based flow control (PFC) on traffic specified by an IEEE 802.1 code point, and apply the profile to an interface.
 | Note: You must configure PFC for FCoE traffic. Each interface that carries FCoE traffic should be configured for PFC on the FCoE code point (usually 011). |
You can attach a maximum of one congestion notification profile to an interface. There is no limit to the total number of congestion notification profiles you can create.
| Note: Configuring or changing PFC on an interface blocks the entire port until the PFC change is completed. After a PFC change is completed, the port is unblocked and traffic resumes. Blocking the port stops ingress and egress traffic, and causes packet loss on all queues on the port until the port is unblocked. |
Options
profile-name—Name of the congestion notification profile.
The remaining statements are explained separately.
Required Privilege Level
interface—To view this statement in the
configuration.
interface-control—To add this
statement to the configuration.
