xoff-state threshold polling-count
When a lossless queue in an interface is not able to forward traffic for a particular duration of time, it is detected as PFC storm. You can
set the duration by providing the number of polling intervals. If a port/priority remains in xoff state for the specified duration, then it is
detected as PFC storm condition.
Syntax
xoff-state threshold polling-count {number of polling-interval}
Parameters
number of polling
interval
Enter the number of polling intervals. The range is from 2 to 10.
Defaults 2
Command Modes CONFIGURATION (conf-storm-control-pfc)

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.
