三层核心交换机的TRUNK端口作为镜像的源端口,应该能抓到ARP包。设过滤器,抓包时间可以长一点。
思科文档的monitor session 命令,关于source:
Specify the SPAN or RSPAN source. A source can be a physical port, a port channel, or a VLAN.
On a trunk interface used as a source port, all VLANs are monitored.
You can monitor traffic on a single port or VLAN or on a series or range of ports or VLANs.
可惜我没有环境测试。
