流量采样配置
要配置流量采样，请在层次结构级别包含 sampling 语句 [edit forwarding-options] ：
[edit forwarding-options] sampling { disable; family (inet | inet6 | mpls) { disable; output { aggregate-export-interval seconds; extension-service service-name; file { disable; filename filename; files number; size bytes; (stamp | no-stamp); (world-readable | no-world-readable); } flow-active-timeout seconds; flow-inactive-timeout seconds; flow-server hostname { aggregation { autonomous-system; destination-prefix; protocol-port; source-destination-prefix { caida-compliant; } source-prefix; } autonomous-system-type (origin | peer); (local-dump | no-local-dump); port port-number; source-address address; version format; version9 { template template-name; } } interface interface-name { engine-id number; engine-type number; source-address address; } } } input { max-packets-per-second number; maximum-packet-length bytes; rate number; run-length number; } traceoptions { file filename { files number; size bytes; (world-readable | no-world-readable); } } }
