Can you mirror ports between two switches in Meraki. eg between a MG250-24 and and a MS 120-8

[TheAlchemist]

Want to take continuous captures on wireshark running on a PC by mirroring port of a remote MS 250 switch port with a local MS 120-8 switch, both on the same network.

Thanks

I don't know the answer, but maybe this can help you.

Hi @TheAlchemist ,

We have a guide for that.

Following the guide, It shows port to mirror on the same switch. Does not give the option to select a port on MS 120-8

In general, you can try to mirror the remote port of the MS250 to the port of your MS120‑8. And then connect your PC to this port using Wireshark. But be sure to make sure that the SPAN settings of the MS250 point to the correct upstream channel. And also that the MS120 transmits the mirrored traffic to your PC without filtering.

I tested it: Remote SPAN seems to be dependent from switch model:
2 C9300-M: no Mirror option
2 MS350-24X: Mirroring possible

2 MS125-48LP: no Mirror option
MS350 and MS125-48LP: no Mirror option

The MS125 does not support RSPAN, so I don't think the 120-8 supports it.

Yes, either same switch or similar model in same network and "stack", will let port mirroring work.
