Description
9.10(0.0)
Introduced on the S6000, S6000–ON, S61000–ON, Z9100–ON.
Usage Information
The
xoff-state threshold polling-count
command is used to set the number of times the polling
should be done. If a port/priority remains in the ‘xoff’ state for the configured threshold number of polling-intervals,
then it would be detected as PFC storm condition. The ‘xoff’ state means no transmission of data happens out of a
port/queue even though there are packets buffered in that queue.
Example
Use the
storm-control pfc
command in the configuration mode to enter the ‘storm-control-pfc'
configuration mode. The commands provisioned in this mode are applicable for all the interfaces that have PFC
storm enabled.
Dell(conf)#storm-control pfc
Dell(conf-storm-control-pfc)#xoff-state threshold polling-count 2
disable storm-control pfc
You can disable the PFC storm globally.

Use the
storm-control pfc
command in the configuration mode to enter the 'storm-control-pfc'
configuration mode. The commands provisioned in this mode are applicable for all the interfaces that have PFC
storm enabled.

Dell(conf-storm-control-pfc)#disable
storm-control pfc in queue-drop
When a PFC storm is detected on a port or priority, you can drop the traffic meant for the specified port or priority, so that the traffic in
other queues is not disturbed. You can apply
storm-control pfc in queue-drop
on an interface, to enable dropping of the traffic
on all the lossless queues of the port.
