Nexus 7000系列交换机ERSPAN配置示例目录简介先决条件要求使用的组件规则背景信息关于ERSPAN配置网络图配置验证相关信息简介本文档介绍如何在Nexus 7000系列交换机上配置封装的远程交换端口分析器(ERSPAN)会话,该会话监控两个不同Nexus 7000系列交换机上以太网端口之间的流量。
先决条件要求尝试进行此配置之前,请确保满足以下要求:具有 Nexus 7000 系列交换机的配置基础知识q具备ERSPAN的基本知识q使用的组件本文档中的信息基于Cisco NX-OS软件版本5.1(3)上的Nexus 7018系列交换机。
本文档中的信息都是基于特定实验室环境中的设备编写的。
本文档中使用的所有设备最初均采用原始(默认)配置。
如果您使用的是真实网络,请确保您已经了解所有命令的潜在影响。
规则有关文档约定的更多信息,请参考 Cisco 技术提示约定。
背景信息关于ERSPANERSPAN支持远程监控网络中的多台交换机。
qERSPAN将镜像流量从不同交换机的源端口传输到网络分析器连接的目的端口。
q流量在源交换机上封装,并传输到目的交换机,在目的交换机上解封数据包,然后发送到目的q端口。
ERSPAN包括ERSPAN源会话、可路由的ERSPAN通用路由封装(GRE)封装流量和ERSPAN目q标会话。
您可以在不同的交换机上单独配置ERSPAN源会话和目标会话。
qERSPAN不监控管理引擎生成的任何数据包,无论其来源如何。
qERSPAN源可监控流量的接口称为ERSPAN源。
q您可以监控源端口的所有数据包,这些数据包接收(入口)、传输(出口)或双向(两者)。
qERSPAN源包括源端口、源VLAN或源VSAN。
当VLAN指定为ERSPAN源时,VLAN中所有支q持的接口都是ERSPAN源。
ERSPAN目标目的端口从ERSPAN源接收复制的流量。
q目的端口是连接到设备(如SwitchProbe设备或其他远程监控(RMON)探测或安全设备)的端口q,可以从单个或多个源端口接收和分析复制的数据包。
