Abstract:
1. A method comprising: accessing, at a network device in a network, information about update frequency of management information base (MIB) object instances that reflects a frequency at which values of the MIB object instances are updated during operation of the network device; selecting, based on the information about the update frequency of the MIB object instances, a subset of the MIB object instances; populating, at the network device, a MIB group with identifiers corresponding to the MIB object instances that are included in the selected subset; receiving, from a network management system (NMS), a request for information about MIB object instances associated with the MIB group; responsive to receiving the request, determining that at least one MIB object instance associated with the MIB group has changed; based on determining the change in the at least one MIB object instance, modifying an existing aggregate change identifier (ACI) for the MIB group to reflect the change in the at least one MIB object instance, wherein an ACI is a checksum computed by aggregating configuration values of the MIB object instances associated with the MIB group, and wherein the existing ACI is computed based on a prior request from the NMS; and sending the updated ACI to the NMS.
