Flow Support

The current version of CA Network Flow Analysis supports NetFlow versions 5, 7, and 9 and the following flow types, provided that they conform to the standards for NetFlow v5, v7, or v9:

• sFlow version 5
• IPFIX
• J-Flow
• cFlow
• Huawei NetStream flow

In order for data from non-sampled flows to appear in reports of 15-minute (historical) data, the following minimum fields are required:

• One of the following: 1 - IN_BYTES, 85 - IN_PERMANENT_BYTES, 231 - FW_INITIATOR_OCTETS, or 232 - FW_RESPONDER_OCTETS
• 4 - PROTOCOL
• 7 - L4_SRC_PORT
• 8 - IPV4_SRC_ADDR
• 10 - INPUT_SNMP
• 11 - L4_DST_PORT
• 12 - IPV4_DST_ADDR

  14 - OUTPUT_SNMP

Note: NetFlow provides a broad view of your network packet streams by creating flow records for all packets. The data from these flow records represents all packets. Sampled NetFlow/IPFIX and sFlow take samples from your packet streams, producing fewer flow records and lessening the impact to a collector. The lower your sampling rate, the less precise the data is likely to be.
