在 VMware Aria Operations for Networks 中,可以為 Cisco 9000 系列交換器設定 NetFlow 收集器。
以下是 Cisco Nexus 9000 的一些裝置命令範例:
- 啟用 NetFlow 功能
configure terminal
feature netflow
end
- 建立流程記錄
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
- 建立流程匯出工具
configure terminal
flow exporter vrni-exporter
destination <PROXY_IP>
transport udp 2055
version 9
source <INTERFACE_NAME>
end
- 為每個介面建立流程監視器
configure terminal
flow monitor vrni-monitor
record vrni-record
exporter vrni-exporter
end
- 設定逾時
configure terminal
cache timeout inactive 30
cache timeout active 60
end
- 在入口模式和出口模式下或至少在入口模式下為每個介面設定流程監視器
configure terminal
interface <INTERFACE_NAME>
ip flow monitor vrni-monitor input
end
