You can do this - I just checked on my UC520 here in the lab on 12.4(20)T. I believe the functionality existed before, but don't have a UC520 on 12.4(11)XW to confirm.
Also - on the CE520, you can also run it.
Go to: http://192.168.1.1/exec/
From there you can 'conf t' and configure it via CLI, like any other IOS switch. It has reduced capabilities, but it can still SPAN.
Not sure what you are suggesting. I know how to get to the CLI. What I am looking for are the commands needed to turn on SPAN. It doesn't look like the UC520 hardware/software support them.
What Nick is saying, he can enter span commands with a newer IOS.
I'm also surprised by that, but it's something certainly worth a try.
yes, you are right, the commands are there. Not sure what I was doing that I didn't see them before.
Thank you very much.
