Ethanalyzer and SPAN
Ethanalyzer is a tool that collects frames that are destined to, or originate from, the Nexus 5000 control
plane. Node to switch or switch to switch traffic can be seen with this tool.
SPAN is a feature whereby frames that are transient to the switch are copied to a second port for
analysis. Node to switch or node to node traffic can be seen via this method.
Ethanalyzer
Ethanalyzer is a Cisco NX-OS protocol analyzer tool based on the Wireshark open source code. This
tool is a command-line version of Wireshark that captures and decodes packets. You can use Ethanalyzer
to troubleshoot your network and analyze the control-plane traffic.
