I need to mirror all ports on my 2980 switch to two different ports simultaneously. I thought I'd read that you could have multiple instances of port mirroring set, but when I tried it, the second one just overwrote the first.

TIA
 
no, you cannot port mirror twice. You can however setup 2 ports to montitor the same thing.

How would I do that?

What I currently have is:
set span 2/1-2/45,3/1-3/34 2/48 inpkts enable

I want to set port 3/14 to be mirrored, as well.

I wondered if I could just change the destination to 2/48,3/14

However, 3/14 is in the range of ports to be mirrored to 2/48 so I'm a little confused.

Thanks
