Polling-interval configuration
The polling interval for an interface is the number of seconds between successive samples of counters sent to the collector. You
can configure the duration for polled interface statistics. Unless there is a specific deployment need to configure a lower polling
interval value, configure the polling interval to the maximum value.
● Change the default counter polling interval in CONFIGURATION mode, from 10 to 300. The default is 20.

Sample-rate configuration
Sampling rate is the number of packets skipped before the sample is taken. If the sampling rate is 4096, one sample generates
for every 4096 packets observed.
