I have a Cisco WS-C2960S-24TS-S switch and would like enable a port mirror for network analyzer (such as Snort). I could not see any options in the GUI interface.
Is it possible, and how do I enable it without a reboot?
You use the command line to enable port mirroring/SPAN, and a reboot is not required.
The below example (from the linked document) will mirror the traffic on Gigabit Ethernet port 0/1 to Gigabit Ethernet port 0/2.
