Maximum Mask Aggregate Output NetFlow

The Maximum Mask Aggregate Output NetFlow feature is an extension of NetFlow accounting that allows one to capture Internet Protocol (IP) flow information on Cisco 12000 series IP Services Engine (ISE) line cards by specifying a maximum source prefix or destination prefix mask that filters flows for the Prefix-Type of Service (ToS) aggregation scheme. NetFlow data is collected on output flows for packets that arrive on a provider edge (PE) router in either Multiprotocol Label Switching (MPLS) or IP format and are transmitted on an egress ISE interface in IP format to a Customer Edge (CE) device.
