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 via 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 via SNMP. The NetFlow MIB request for information is sent from an NMS workstation via SNMP to the router and is retrieved from the router. This information can then be stored or viewed, thus allowing NetFlow information to be easily accessed and transported across a multi-vendor programming environment.
