CISCO-NETFLOW-MIB
SNMP is used to collect network information. SNMP permits retrieval of critical information from
network elements such as routers, switches, and workstations. The CISCO-NETFLOW-MIB feature uses
SNMP to configure NetFlow and to gather NetFlow statistics.
The CISCO-NETFLOW-MIB contains objects that allow NetFlow statistics and other NetFlow data for
the managed devices on your system to be retrieved by SNMP. You can specify retrieval of NetFlow
information from a managed device (for example, a router) either by entering commands on that
managed device or by entering SNMP commands from the NMS workstation to configure the router
through the MIB.
If the NetFlow information is configured from the NMS workstation, no access to the router is required
and all configuration can be performed through SNMP. The CISCO-NETFLOW-MIB request for
information is sent from an NMS workstation through SNMP to the router and is retrieved from the
router. This information is stored or viewed, thus allowing NetFlow information to be easily accessed
and transported across a multivendor programming environment.
The CISCO-NETFLOW-MIB feature defines managed objects that enable a network administrator to
remotely monitor the following NetFlow information:
• Flow cache configuration information
• NetFlow export information
• General NetFlow statistics
