Configuring Priority Flow Control
Note For Cisco Nexus 9200 platform switches, Cisco Nexus 9300-EX/FX/FX2 platform switches, and Cisco Nexus
9500 platform switches with -EX or -FX line cards, one of the following calculations is performed to determine
when the queue is moved to the shutdown state:
If the interface multiplier is configured, the following calculation is performed:
priority-flow-control watch-dog interval value * priority-flow-control watch-dog
internal-interface-multiplier multiplier
If the interface multiplier is not configured, the watchdog shutdown multiplier is used instead:
priority-flow-control watch-dog interval value * priority-flow-control watch-dog shutdown-multiplier
multiplier

Configuring a Priority Flow Control Watchdog Interval
Purpose
Enters global configuration mode.
Configures a value for the PFC auto-restore multiplier.
Configures a value for the PFC fixed-restore multiplier.
Globally enables or disables the PFC watchdog interval
for all interfaces. This command should be configured at
global and also at an interface.
See the following example of the command configured at
global:
switch(config)# priority-flow-control
watch-dog-interval on
