Hi Priscilla, Hi Group,
I used the SPAN functionality often on remote sites with Catalyst 2924XL
and Catalyst 6000 switches. As sniffer device i used a unix workstation
on the remote network that was able to run a basic protocol analyzer
(tcpdump, snoop). I setup and operated SPAN functionality and the tool
on the workstation all remotely and it worked always fine. So i would say
yes to the question, the sniffer-like device is able to send data. It has
been a while since i used this (previous workplace) but if remember
correctly on the cat6000 was a special parameter that allowed the port used
as SPAN port to send data.
