code-point (Input Congestion Notification)


Hierarchy Level


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.


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.
