本节给出了在Juniper设备上配置cflowd/J-Flow导出的步骤。要启用采样并将流记录导出到指定目标地址,请执行以下命令:
forwarding-options { sampling { input { family inet { rate 100; run-length 9; max-packets-per-second 7000; } } { cflowd <destination address>{ port <port number>; source-address <source address>; version <version number>; no-local-dump; autonomous-system-type origin; } } } }
要在特定接口上启用数据包采样,从而进行Flow包分析,请按照以下步骤操作:
interfaces { ge-1/3/0 { vlan-tagging; unit 101 { vlan-id 101; family inet { sampling { input; output; } address 206.80.253.26/25 } } } }
