Abstract:
1. A method comprising steps of: detecting, by a Simple Network Management Protocol (SNMP) agent residing on a managed device, that one or more objects in a management information base (MIB) of said managed device have changed; said SNMP agent generating a bitmap containing a plurality of bits, wherein each bit of the plurality of bits indicates whether an individual object of said MIB has changed or has not changed; wherein generating the bitmap includes at least setting bits, of the plurality of bits, which correspond to the one or more objects to indicate that the one or more objects have changed; and said SNMP agent storing said bitmap on said managed device for later access by a network management system (NMS) that resides on another device that is communicatively coupled to said managed device through a computer network; wherein said steps are performed by one or more computing devices.
