Command History
This guide is platform-specic. For command information about other platforms, see the relevant Dell Networking
OS Command Line Reference Guide.
Version 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 ‘xo’ state for the congured threshold number of polling-intervals,
then it would be detected as PFC storm condition. The ‘xo’ state means no transmission of data happens out of a
port/queue even though there are packets buered in that queue.
Example Use the storm-control pfc command in the conguration mode to enter the ‘storm-control-pfc'
conguration 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
storm-control pfc in queue-drop
When a PFC storm is detected on a port or priority, you can drop the trac meant for the specied port or priority, so that the trac in
other queues is not disturbed. You can apply storm-control pfc in queue-drop on an interface, to enable dropping of the trac
on all the lossless queues of the port.
