Polling Interval – Denotes the time the MTU-M waits between successivestarts of the polling cycle. If all of the nest cards can not be polled in thisamount of time they may be skipped. Pollto – Denotes the maximum amount of time, in 256th seconds, that theMTU-M will wait between the polling of each line card.For example, if you have 51 nest cards:1. Set your polling range from 2–51 (slot 1 is the MTU-M).2. Set initial Pollto to 50/256th seconds (.195 seconds).3. Set Polling Interval to10 (51 nest cards * .195 seconds = 9.945)If you find that all of your nest cards are not being polled, you may need toadjust these values.
