In some example embodiments, a apparatus and method are shown that include receiving a subscription instruction identifying a subscription to management information from a network device. Additionally, the apparatus and method includes periodically retrieving the management information from the network device. Further, the apparatus and method includes formatting the management information according to an export template. The apparatus and method also includes transmitting the management information utilizing a protocol. A apparatus and network device are also shown that include receiving a management information snapshot as part of a periodic subscription. This apparatus and method includes processing the management information snapshot based upon an export template, the export template defined as part of an IPFIX protocol.

Particular embodiments provide a virtual responder that can be contacted by any number of senders. When a sender wants to perform a measurement test with a real responder, the sender sends a control message to a virtual responder. The virtual responder is configured to determine a real responder based on real responder selection metrics. The virtual responder may poll the real responders at certain times to receive the real responder selection metrics. The virtual responder then selects a real responder from a plurality of real responders based on the real responder's selection metrics. The virtual responder then sends contact information for the selected real responder to the sender device. This allows the sender device to contact the selected real responder to perform the measurement test with a real responder.

In one embodiment, a networking device includes logic encoded in one or more tangible media for execution and when executed operable to cause performing receiving a command to collect a unique object identifier that represents a unique management information base (MIB) object; retrieving, in response to receiving the command, a Simple Network Management Protocol (SNMP) MIB variable or table that corresponds to the MIB object; creating an Internet Protocol Flow Information Export (IPFIX) template data structure that includes the object identifier; in which the object identifier is encoded in the IPFIX template data structure as a string that has a variable length; and exporting the encoded object identifier with the variable length string.
摘要:
A method of persisting SNMP (Simple Network Management Protocol) variable values associated with SNMP object IDs for an SNMP managed network element across network element reloads comprises implementing a generic persist operation at the network element; and defining, in conjunction with the generic persist operation, at least one object ID for which a value is to be persisted.
