History
Usage You can configure a maximum of four lossless (PFC) queues. By configuring four
Information lossless queues, you can configure four different priorities and assign a particular
priority to each application that your network is used to process. For example, you
can assign a higher priority for time-sensitive applications and a lower priority for
other services, such as file transfers. You can configure the amount of buffer space
to be allocated for each priority and the pause or resume thresholds for the buffer.
This method of configuration enables you to effectively manage and administer the
behavior of lossless queues.

Introduced on the MXL platform.
Enter the input policy name with the PFC configuration to an
ingress interface.
Introduced on the M I/O Aggregator. This command is
supported in Programmable-Mux (PMUX) mode only.
Introduced on the MXL 10/40GbE Switch IO Module.
You can enable link-level flow control on the interface. To delete the input
policy, first disable link-level flow control. PFC is then automatically enabled on
the interface because an interface is by default PFC-enabled.
PFC still allows you to configure lossless queues on a port to ensure no-drop
handling of lossless traffic.
