Type of Service (ToS) value
The union of all TCP flags observed over the life of the flow (TCP flows).
Layer 3 Routing information, including:
IP address of the immediate next-hop along the route to the destination
Source and destination IP masks (prefix lengths in CIDR notation)
Configuring Flow sources is a three-part process:
1 Configuring Flow devices to send Flow data to Flow Monitor. For more information, see
Manually configuring devices to export flow data to Flow Monitor (on page 973).
2 Configure Flow Monitor to listen for flow data on the appropriate port. For more
information, see Configuring Flow Monitor to listen for NetFlow data (on page 993).
3 Setting options for the Flow source in Flow Monitor.
SNMP Polling
While Flow Monitor normally receives flow data from a flow source, it can also poll a source
using SNMP to gather data from a network device. Flow Monitor can actively poll a source for
the following data:
Total interface traffic. Provides summary data for incoming and outgoing interface
traffic.
NBAR information. Provides summary data for each application identified using
Cisco Systems Network Based Application Recognition (NBAR) technology.
CBQoS information. Provides summary data for each class in the Quality of Service
class map for the interface. Before you can view meaningful reports, you must
configure Flow Monitor and Flow-enabled devices, such as routers or switches, to
communicate network activity back to the Flow Monitor listener application.
Configuring Flow Monitor to listen for NetFlow data
Use the Listener port settings on the Flow Settings to configure Flow Monitor to listen for
NetFlow data. You can enter the TCP/IP port numbers which the Flow Monitor collector
service should use to listen for flow information in the Listener port box. Flow Monitor can
listen on one or more ports, with port 9999 being the default. The sources sending flow
information to Flow Monitor must send data using one of these ports.
Note: If you configure Flow Monitor to listen on more than one port or on a port other than
the default port, you should verify that the port is not being used by another service and
ensure that an exception is added to the firewall if you are using Windows Firewall.
