seconds
Enter the polling interval in milliseconds. The range is 200 to 1000. The interval
should be entered in multiples of 100. The default interval value is 100 milliseconds.

Usage
Information
The polling—interval command is used to set the interval in milliseconds to poll the queue traffic
and egress counters. You can use the polling results to detect the inconsistencies in the PAUSE frames
received .
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.
DellEMC(conf)#storm-control pfc
DellEMC(conf-storm-control-pfc)#polling-interval 200
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
