This section gives the steps to configure cflowd/J-Flow export on Juniper devices.To enable sampling and to export the flow records to specific destination address, follow the below command:
forwarding-options { sampling { input { family inet { rate 100; run-length 9; max-packets-per-second 7000; } } output { cflowd <destination address>{ port <port number>; source-address <source address>; version <version number>; no-local-dump; autonomous-system-type origin; } } } } |
To enable packet sampling on the particular interface(s), from which flow analyzis to be done follow the below steps:
interfaces { ge-1/3/0 { vlan-tagging; unit 101 { vlan-id 101; family inet { sampling { input; output; } address 206.80.253.26/25 } } } } |
