Description: The MIB module to track and store the modifications in data of NMS specified MIB tables implemented in an SNMP command responder (traditionally called an SNMP agent).

This MIB allows an NMS to register for change monitoring in the tables it is interested in. This MIB then tracks modifications in those registered tables, allowing the NMS to poll one table to determine if others need to be polled.

This MIB keeps track of all modifications, including adding a new row, deletion of a row, and modification of an object in a row. It can also be configured to send change notifications to an NMS.
