Can not capture wireshark

Zawgyi — Mon, 13 Apr 2026 13:13:21 GMT

Hi everyone,
Here is my configuration.

create mirror AnalyzerMirror
enable mirror AnalyzerMirror to port 1 (Destination port)
configure mirror AnalyzerMirror add vlan 10 (Source Vlan)

But I did not received the traffic when captured the traffic wireshark.
Could you please correct my config if something wrong?

Seems like it is configured correctly. https://extreme-networks.my.site.com/ExtrArticleDetail?an=000074211

You may want to contact GTAC and have them take a look.

Your configuration is close, but the issue is likely with how the mirror source and destination are defined. You need to ensure the destination port is not part of the source VLAN and is configured only as the analyzer port. For example:

create mirror AnalyzerMirror
configure mirror AnalyzerMirror add vlan 10
enable mirror AnalyzerMirror to port 1

Make sure port 1 is not in VLAN 10 and is dedicated to Wireshark capture. Mixing source and destination roles on the same port or VLAN will prevent mirrored traffic from being received.
