FastNetMon’s latest release brings several improvements to our IPFIX and Netflow v9 logic. We’ve migrated away from be_copy_function in IPFIX logic, reworked IPFIX sampling logic, and addressed a bug with 2 byte sampling rate decoder in Netflow v9 for Cisco specific encoding format. See below the full list.
Changes:
- Migrated away from be_copy_function in IPFIX logic and removed this function
- Added pcap for Juniper IPFIX sampling rate encoding to test suite
- Reworked IPFIX sampling logic which used IPFIX_SAMPLING_PACKET_INTERVAL encoding
- Reworked Juniper Netflow v9 sampling decoding logic to explicitly use 2 and 4 byte encoding
- Addressed bug with 2 byte sampling rate decoder in Netflow v9 for Cisco specific encoding format. Bug caused abnormal traffic counter values and was introduced in 2.0.353
