The Device Poll Interval lets you specify how frequently the EPICenter server should
pollthefordetaileddeviceinformation,such assoftwareversion,bootromversion,and
soon.ThisalsoincludesEDPand ESRPinformationfornon-”i”seriesdevices.Toavoid
a potentially large amount of polling traffic, this detailed polling is only done every 30
minutes for core (chassis) devices, and every 90 minutes for edge devices. You can
change this detailed polling interval by entering a different value in this field.
Note that the Device Poll Interval set here is different from the global Poll Interval
you can set in the Administration applet. The global poll interval controls the
basic status polling needed to ensure SNMP reachability, and is typically done
much more frequently than detailed device polling.

If you change the community string for a device so that it no longer matches the
string configured in the device, EPICenter will no longer be able to communicate
with the device. For Extreme devices, EPICenter will display an error message, but
it will not necessarily do so for third-party devices. To avoid this problem, change the
community string on the device first, then change it in EPICenter.
