[edit class-of-service congestion-notification-profile profile-name input dscp] [edit class-of-service congestion-notification-profile profile-name input ieee-802.1]
Description
Enable priority-based flow control (PFC) on an IEEE 802.1p code point (priority) or a Differentiated Services code point (DSCP) value (to implement DSCP-based PFC at Layer 3).
Use this statement to configure PFC to operate based on an IEEE 802.1p code point in the VLAN-tagged packet header at Layer 2, or on a DSCP value from the Layer 3 IP header to support PFC with untagged traffic.
The pfc statement is mandatory when setting this
statement.
Options
code-point-bits—Code point bit pattern corresponding to an IEEE 802.1p 3-bit
priority value when used in the ieee-802.1 hierarchy, or
a 6-bit DSCP value when used in the dscp hierarchy.
The remaining statements are described separately.
Required Privilege Level
interfaces—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
Release Information
Statement introduced in Junos OS Release 11.1.
