在 vRealize Network Insight 中,可以为 Cisco Nexus 9000 系列交换机配置 NetFlow 收集器。
以下是 Cisco Nexus 9000 的一些设备命令示例:
- 启用 NetFlow 功能
configure terminal
feature netflow
end
- 创建流记录
configure terminal
flow record vrni-record
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
- 创建流导出器
configure terminal
flow exporter vrni-exporter
destination <PROXY_IP>
transport udp 2055
version 9
source <INTERFACE_NAME>
end
- 为每个接口创建流监控器
configure terminal
flow monitor vrni-monitor
record vrni-record
exporter vrni-exporter
end
- 配置超时
configure terminal
cache timeout inactive 30
cache timeout active 60
end
- 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 vrni-monitor input
end
