RSPAN on EXOS

Amir90 — Tue, 14 Jul 2026 13:58:38 GMT

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?

Hello,
On SW2, you are mirroring port 4 to the remote VLAN, but make sure port 1 is actually connected to the RSPAN trunk path toward SW-Mid. The remote-tag setting only adds the VLAN tag; it does not automatically create the VLAN transport.

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.
