Enter the scan interval to be assigned to the device (default is 1000). The scan
interval is the target time in milliseconds at which the current device will be scanned;
it is the scan time which could be achieved under optimal circumstances. This will
vary greatly from network to network, depending upon the number and type of
devices being managed, the amount of data being requested by the client
applications, and even the architecture of the network itself. The valid range for scan
interval is 1 to 9999999; scan intervals less than 100 milliseconds are usually
impossible due to network timing constraints.
