I only capture in one direction

0

Hi; I configure a switch Catalyst in monitor mode to capture some packets, with my laptop I only capture packets in one direction; I use another laptop with same Wireshark version and I capture traffic in both directions, I can check this with a Ping. In my laptop I just see ICMP (Echo) Requests w/o any filter but when I use the another one I see Echo Requests and Replies.

So I don't know what else I must change in the original laptop to receive and capture traffic in both directions.

I assume you're plugging the two laptops into the same port on the Catalyst switch.

Are you capturing in promiscuous mode on both laptops?

What versions of which operating systems are running on the two laptops?
