Re: How to check port mirroring is working or not?
I concur with James, the only way you are 100% positive is:
1-Check your sniffer is receiving data.
2-Even when you see data, remove SPAN port config to make sure the data you see on sniffer is your session (I usually shut the port I am spanning if its not service affecting). The reason is that I have seen that sometimes sniffer is getting all sort of junk you are not really spanning for, especially when using ERSPAN.
