请教: netflow Analyzer收不到数据的问题？

tysai

我在cisco 2600的FastEthernet 0/0 上设置了ip,可以ping 通装有netflow Analyzer的机子。\r\n也开启了netflow 协议\r\nshow ip flow export结果如下：\r\nFlow export is enabled\r\n  Exporting flows to ***.***.***.***(9991)\r\n  Exporting using source IP address ***.***.***.***\r\n  Version 5 flow records\r\n  199 flows exported in 126 udp datagrams\r\n  0 flows failed due to lack of export packet\r\n  126 export packets were sent up to process level\r\n  0 export packets were dropped due to no fib\r\n  0 export packets were dropped due to adjacency issues\r\n但是netflow Analyzer还是显示：\r\n目前没有路由器正在向NetFlow分析仪输出NetFlow数据包。 \r\n请问可能是什么问题啊？\r\n\r\n我在装有netflow Analyzer机子上用sniffer抓包也没有抓到netflow数据
