Abstract:
1. A networking environment comprising: a network element containing a managed object; a network management station (NMS) generating a request specifying an element in said managed object; a first proxy forwarder receiving a first packet containing said request according to a network management protocol from said NMS, wherein said request specifies an operation on said managed object, wherein said network management protocol comprises simple network management protocol (SNMP); and a last proxy forwarder receiving said request from said first proxy forwarder according to said network management protocol and forwarding said request to said network element in a last packet, wherein said network element receives said request from said last proxy forwarder and performs said request on said managed object to generate a response to said request, wherein said first packet specifies an AuthEngineID equaling an OwnEngineID of said first proxy forwarder and a ContextEngineID equaling an OwnEngineID of said network element, wherein said first proxy forwarder sends said request in a second packet to a third proxy forwarder, said second packet specifying a AuthEngineID equaling said OwnEngineID of said network element, wherein said first proxy forwarder receives from said third proxy forwarder a error PDU containing an OwnEngineID of said third proxy forwarder, said first proxy forwarder re-sending said request in a third packet to said third proxy forwarder, wherein said third packet contains an AuthEngineID equaling said OwnEngineID of said third proxy forwarder.
