Hi everyone,
I followed the configuration instructions in this post, but I still can't get RSPAN to work. Can anyone help, please?
https://extreme-networks.my.site.com/ExtrArticleDetail?an=000080241
Here is my topology and my configurations:
SW2:
create mirror Remote
configure mirror Remote to port 1 remote-tag 100
configure mirror Remote add port 4 ingress-and-egress
enable mirror Remote
SW-Mid:
create vlan remote-mirror
configure vlan remote-mirror tag 100 remote-mirroring
configure vlan remote-mirror add ports 1-2 tagged
SW1:
create vlan remote-mirror
configure vlan remote-mirror tag 100 remote-mirroring
configure vlan remote-mirror add ports 1 tagged
configure vlan remote_mirror add ports 5 untagged
I have Wireshark on analyzer PC and I can catch data when I set up SPAN but I cant capture any data when I set up RSPAN.
Any idea or any mistake I did here?
Solved! Go to Solution.

Hi,
thanks for your message. I also thought this could be a problem, so I created VLAN 100 on SW2 and added it as tagged on port 1, but that didn't help either.

I tried your suggestion today, and the results were better than I expected. The instructions were simple, accurate, and easy to follow. Thank you for taking the time to share them.

I found the troubleshooting discussion helpful because it explains RSPAN clearly. The notes about VLAN tagging, trunk paths, and configuration details make diagnosing missing mirrored traffic much easier for beginners.

Hello, On SW2, you are mirroring port 4 to the remote VLAN, but make sure port 1 is actually connected…

I love how this muffin recipe brings back the classic bakery-style texture. The tips about resting batter and choosing the right ingredients make the method especially useful for home bakers.Visit
