为 Cisco 4500 系列交换机配置 NetFlow 收集器

在 vRealize Network Insight 中，可以为 Cisco 4500 系列交换机配置 NetFlow 收集器。

1. 创建流记录

   configure terminal

   flow record netflow-original

   match ipv4 protocol

   match ipv4 source address

   match ipv4 destination address

   match transport source-port

   match transport destination-port

   match interface input

   collect transport tcp flags

   collect counter bytes

   collect counter packets

   collect timestamp sys-uptime first

   collect timestamp sys-uptime last

   End

2. 创建流导出器

   configure terminal

   flow exporter e1

   destination <PROXY_IP>

   transport udp 2055

   end

3. 创建流监控器

   configure terminal

   flow monitor m1

   record netflow-original

   exporter e1

   end

4. 配置超时

   configure terminal

   cache timeout inactive 30

   cache timeout active 60

   end

5. 在输入模式和输出模式下或者至少在输入模式下为每个接口配置流监控器

   configure terminal

   interface <INTERFACE_NAME>

   ip flow monitor m1 unicast input

   end
