I have a rather large home network with dozens upon dozens of devices, a router in AP mode, and 5 or 6 unmanaged switches. At least 20 wired devices and 30 wireless devices.
About once a month, the whole wired part of the network goes down (my openwrt router's wifi still works, AP does not).
Plugging in wireshark into one the ports on the central unmanaged switch, I get almost all MAC-specific-ctrl-proto-01 packets / MAC CTRL / Pause packets. I suspect I'm getting into an ARP storm and eventually one of the unmanaged switches has hit its limits.
I'd like to begin segmenting my network, but I don't have any idea on how to start. I learned about the OSI model in school, but never really dove into it in practice.
Is a VLAN what I would want? I would still like layer 3 communications to work between VLANs, but want to isolate layer 2 traffic into smaller segments.
If a VLAN is what I want, is there a way to do that in OpenWRT 21 with Luci? I watched some videos on setting up VLANs, but it looks like the settings in OpenWRT have since changed.
Thanks, any advice appreciated.
