Syntax
priority-flow-control priority priority-list {drop | no-drop}
no priority-flow-control priority
• drop—Disable lossless behavior on the selected priorities.
• no-drop—Enable lossless behavior on the selected priorities.
• priority-list —A list of IEEE 802.1p priorities (up to two) which are to be
configured as lossless.
Default Configuration
The default behavior for all priorities is tail-drop.
Command Mode
Datacenter-Bridging Configuration mode
User Guidelines
NOTE: This command is only available on N40xx series switches.
The administrator must configure the same no-drop priorities across the
network in order to ensure end-to-end lossless behavior. Ports that are
configured to use the DCBX auto-configuration roles (auto-up or auto-down)
have their PFC settings overridden. Only ports configured as DCBX manual
role utilize the configured PFC settings.
Example
The following example sets priority 3 to no drop behavior.
s1(config)#interface te1/0/1
s1(config-if-Te1/0/1)#datacenter-bridging
s1(config-if-dcb)#priority-flow-control mode on
s1(config-if-dcb)#priority-flow-control priority 1 no-drop
clear priority-flow-control statistics
Use the clear priority-flow-control statistics command to clear all or interface
Priority-Flow-Control statistics.
