I've just installed 2 of these in my workplace on a PLC network.
I'm now looking to set one of the ports up as my diagnostic port and would like to be able to mirror any of the other ports to this port.
I believe it is called SPAN on Cisco switches.
The only reference I can find to it is configuring via Telnet which I haven't got a clue about.
On my old Wiedmuller switches it was just a few clicks away.
Could anyone shine some light on the process for me.
Thanks in advance, Colin

I'd found that page but it made little sense to me.
I can configure port mirroring on the Wiedmuller switches web based interface.
I don't have a clue where to start on these things.
How do I enter the text commands to the switch to enable span?
Do Cisco supply/sell any software which will make it more (not very experienced)user friendly?
Best regards, Colin
You are correct it is called SPAN.
A simple SPAN (or PORT MIRROR) is
to set which port will be monitored and which port will the
from config mode
mon sess 1 source interface g0/22
mon sess 1 destination interface g0/24
show mon sess 1
When you are finished monitoring you
turn it off by
no mon sess 1
