The title already says a lot, so we have 3 3com Switches type 3870 stacked together at the back. I want to monitor a pc with wireshark. My own pc is on unit 2 port6 and the pc I try to monitor is on Unit2 port 7. When I go to the mangement website from the switch I try to setyp the roving analysis as described but I get a error saying "invalid data"? Any ideas on this

I am not sure on using the Web interface in setting this up as I have never used their GUI (Always seemed to run into a bug somewhere).  Have you tried configuring this from the CLI?

Should be under ports settings.  From the menu you should be able to set up the port mirroring. I believe the settings would be similar to the following depending on the software version the switch is running:

feature --> rovingAnalysis ---> add

Thx for your input, we indeed also tried to use the CLI, but that didn't work either.

It seems that you cannot enable LACP on the ports on which you are monitoring. Case solved
