the switch is not even there. It should, I suppose.
The arp cache will only list IPv4 devices that have recently sent traffic to the computer where you're looking at the cache. If nothing happens for a period of time, everything in the cache will expire. The ip neighbor show command lists both IPv4 and IPv6 addresses, but again they will expire.
I will not be able to see them, and also, I don't what packages to look for.
???? Wireshark is included with openSUSE. Just install it. You can then use it to monitor network traffic. I suggested using it to display only those link local packets and then see what happens when you disconnect one device at a time from your switch.
ISP--fibre--[Main router]---[switch]---[R-W-A.P.]-- R-W-A.P. is Router used as "WiFi-Access Point" My computer is connected to the switch. If, as I believe, the traffic is between the router and the R-W-A.P. (see Florian post and my response), the switch may not send those packages to my computer.
You might not even see the switch. While they do have MAC addresses, unmanaged switches don't normally communicate with other devices. They just pass traffic, with the original MAC intact. However, you should be able to see spanning tree protocol frames, from most switches, with Wireshark. Spanning tree is a method that switches use to avoid loops. All but low end switches use it. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
