Re: How do I get Ethanalyzer to display the packets in the CLI?
Ethanalyzer will show you control-plane packets (packets destined to the switch or originated from the switch) but it is not meant to be used for troubleshooting data-plane (traffic through the switch). I'm guessing you're attempting the latter which is why it is not capturing them.
Depending on the Nexus platform you are working with and its NX-OS version, you can temporarily configure a SUP SPAN (which essentially mirrors data plane traffic to the supervisor) to troubleshoot but definitely not recommended to leave this on long term.
What platform/NXOS are you running? I can check if supported and provide you with a sample configuration.
As far as how the capture/display filters work, it's essentially Wireshark if you're familiar with that. We do have a good starter guide here for Ethanalyzer as well.
