Introduced on the MXL platform.
Usage
Information
You can configure a maximum of four lossless (PFC) queues. By configuring four
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.
Example
Dell(conf-if-te-0/0)#dcb-policy buffer-threshold test
dcb-policy input
Apply the input policy with the PFC configuration to an ingress interface.
Syntax
dcb-policy input
policy-name
To delete the input policy, use the
no dcb-policy input
command.
Parameters
policy-name
Enter the input policy name with the PFC configuration to an
ingress interface.

Usage
Information
If you apply an input policy with PFC disabled (
no pfc mode on
):
• 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.
When you apply an input policy to an interface, an error message is displayed if:
