Netflow commands
The BSGX4e implements a Netflow exporter. It monitors incoming traffic
and reports it to the Netflow collector. Netflow versions 1, 5, and 9 are
supported.
The Netflow exporter must be deployed together with a Netflow collector.
The exporter and collector must implement the same Netflow version.
To classify traffic into the flow to be monitored, the Netflow exporter applies
filters to the traffic received on the interfaces. The filters can apply to:
z Port (source or destination)
z IP address (source or destination)
z IP ToS tag value
z IP protocol
z Ethernet protocol
z MAC address (source or destination)
z Interface
When more than one filter is specified, a logical AND is applied.
For the monitored traffic flow, the Netflow exporter reports the following
information to the Netflow collector:
z Source IP address (IPV4_SRC_ADDR)
z Destination IP address (IPV4_DST_ADDR)
z Protocol (PROTOCOL)
z Source port (L4_SRC_PORT)
z Destination port (L4_DST_PORT)
z Number of packets received (IN_PKTS)
z Number of bytes received (IN_BYTES)
z Time since flow creation (FIRST_SWITCHED)
z Time since last update (LAST_SWITCHED)
Use the following commands to configure Netflow:
z netflow agent
z netflow filter
